8D Problem Solving is a systematic and structured approach used to solve business related problems. It names has been given by the fact there are 8 steps or 8 disciplines that are followed to identify, correct and eliminate recurring problems.

8D Problem Solving is regarded as robust methodology that has proven its worth across multiple industries and manufacturing in particular. The methodology was Initially developed within the automotive industry, it has since been widely adopted in manufacturing, logistics and health care to name a few. The 8D approach goes beyond helping team just identify the root cause of problem but also provides a structured approach for implementing and verifying corrective actions.

What is 8d problem solving.

The 8D Problem-Solving methodology was developed in the late 1980s  by Ford Motor Company. The term “8D” stands for “Eight Disciplines,” which represent the eight critical steps in problem-solving.

Initially it was only intended to resolve issues within the automotive manufacturing process. However, over the year since then the methodology has gained universal acceptance and is now applied across various sectors. The 8D approach was heavily influenced by quality management systems like Total Quality Management (TQM) and methodologies like Six Sigma and forms a key part of quality roles and Six sigma qualifications.

8D is also encourages collaborative team based approach to addressing issues in the workplace This methodology was purposefully designed to be a cross-functional effort, ensuring to bring together expertise from different departments or disciplines to comprehensively address an issue by looking at it from all point of view. Here are the key components:

Preparation : Before diving into problem-solving, the team gathers all necessary resources and tools.

Team Establishment : A cross-functional team is assembled, each member having a specific role and responsibility.

Problem Description : The issue at hand is clearly defined to ensure everyone has a shared understanding.

Interim Actions : Short-term solutions are implemented to contain the problem and prevent further damage.

Root Cause Analysis : Various tools and methods are used to identify the real cause of the problem.

Permanent Corrective Actions : Long-term solutions are selected and verified to eliminate the root cause.

Implementation : The long-term solutions are implemented across the board, including necessary changes to policies and procedures.

Prevent Recurrence : Measures are taken to ensure that the problem does not occur again.

Team Recognition : The team is congratulated and acknowledged for their efforts.

How does 8D Compare to over Problem-Solving Methods?

Between quality management systems and lean six sigma there are several problem-solving methodologies such as PDCA (Plan-Do-Check-Act), DMAIC (Define-Measure-Analyze-Improve-Control), and A3 . However the combination of the 8D steps results in a comprehensive frame work that is:

Team-Oriented : Unlike some methodologies that can be carried out by individuals, 8D strongly emphasizes team collaboration as a core principle as seen in steps D1 and D8.

Structured Framework : 8D provides a very detailed, step-by-step guide for solving complex problems, by breaking it down in to logical steps making it easier to manage and track progress.

Broad Applicability : While some methodologies like DMAIC are closely tied to Six Sigma, 8D can be applied in various contexts without being tied to a particular quality management system.

Focus on Prevention : 8D not only aims to solve the problem but also focuses on implementing changes to prevent its recurrence, making it a complete approach to problem solving.

The 8 Disciplines Explained

D0: prepare for the process.

Before you start 8D you should prepare for the 8D process. This phase sets the foundation for the entire methodology, ensuring that the team is able to tackle the problem effectively. Therefore, effective preparation helps in avoiding unnecessary delays and ensures that you’re not solving the wrong problem.

Within the initial preparation step you should also the time to think about what knowledge, expertise and experience you need within the team. Cross-functional teams are important, as they bring alternative perspectives and skills to the table rather than everyone looking at the problem from one point of view. Make sure you consider expertise, availability, and interest when selecting team members.

D1: Establish the Team

In D1 you should establish the team by clearly defining the roles and responsibilities for each team member. This includes assigning a team leader, subject matter experts, and roles for data collection , analysis, and communication this helps to provide the team members clarity on how they will be involved and contribute to the success of the problems solving activity.

Team Composition

Once roles are defined, where possible ensure that the team is balanced in terms of skills and expertise. A well-rounded team will be more effective in tackling various aspects of the problem.

Communication

Establish clear methods communication, both within the team and with external stakeholders. Such as deciding on regular meeting schedules that everyone can attend, reporting formats, and tools for collaboration.

D2: Describe the Problem

In D2 it is time to create a well formed problem statement. This step is key as it provides a foundation for understanding the problem which will lead to generally more successful problem-solving. It ensures that everyone clearly understands what needs to be addressed, setting the scope for the entire process. Ensure that the problem is clearly understood by everyone in the team at this stage to prevent confusion later on in the process.

5W1H Method of creating a Problem Definition

Use data gathering techniques such as observations, interviews, and document reviews can help to precisely identify the problem. A useful tool to use at this stage could be the 5W1H Problem definition method.

You can find out more about this method with our 5W1H guide .

Problem Definition – is / is not template

When creating your problem definition ensure to be specific, measurable, and unambiguous when stating the problem. You should avoid generalities and ensure that the problem statement is understandable to someone unfamiliar with the issue. If you are new to this process it may be helpful to give the statement to someone unfamiliar to the process and see if they understand it or if they have questions. You can then clarify any questions by adjusting the problem description to improve the claity.

D3: Implement and Verify Interim Actions

In D3 while the team is investigating the root cause, interim actions are must be implement to contain the problem and minimize its impact. This is particularly important in critical situations affecting safety, compliance, or customer satisfaction. 

In this step you should identify, plan, and execute short-term fixes that can quickly contain the problem. This could include quarantining the product to ensure it is not sent out to the customer or even pausing production lines that continue to product defects. Ensure these actions are documented for future reference.

Use metrics and KPIs to gauge the effectiveness of the interim actions. Make adjustments as necessary.

D4: Root Cause Analysis

D4 is where you start to understand what is causing the issue by identifying the underlying reason for the problem. The objective is to find the root cause, not just the symptoms.

At this stage there are a range of quality and lean six sigma tools that can be used to conduct root cause analysis , which can include the Fishbone Diagram for structured brainstorming and the 5 Whys technique for causal chain analysis.

We have a range of guides on all of these techniques for you to use.

Once identified, it is important validate the root cause through experimentation or additional data analysis to ensure it’s the actual cause and not a symptom, this can often be an overlook critical step in the root cause process.

D5: Choose and Verify Permanent Corrective Actions

In D5 you need to choose what actions to be taken to prevent the problem reoccurring and any solutions implemented should be verified that the actions correct the problem this can involve trial runs, further data collection and inspections of product or services being produced.

You should also consider factors like cost, impact, and feasibility when choosing a permanent corrective action and should also conduct a risk assessment to evaluate potential negative outcomes of the actions taken

An implementation or action plan is often useful to document at this stage to detail the steps for implementation, assign responsibilities, and set timelines.

D6: Implement Permanent Corrective Actions

Once verified, implement the corrective actions across all relevant departments or processes. This can involved documenting the new process and training out to all stakeholders involved to ensure the new process is followed and that the stakeholders understand the reason for the change.

At this point you should continue to regularly monitor the situation to ensure the corrective actions are sustained and effective, this could be for a period of 30, 60 or 90 days after the problem was resolved to ensure the new process has become a sustained and issues do not reoccur. 

D7: Prevent Recurrence

In D7 to prevent recurrent you should review and update organizational policies or standard operating procedures (SOPs) to prevent a recurrence of the problem and document the new standard process

It is important to conduct regular reviews to continuously monitor the process and ensure procedures are being followed but also to identify further opportunities for process improvement.

D8: Congratulate the Team

The final step D8, after the hard work and successful problem resolution, it is important to acknowledging and congratulating the team is vital for morale and future engagement. With the recognition of a successful 8D Problem-solving activity complete you are more likely to encourage future participation as the method gets a reputation as being useful and successful at solving problems. 

Whether it’s a team lunch, certificates of achievement, or simply a public acknowledgment, celebrate the success in a way that resonates with your team.

Finally it is always important to conduct a lessons-learned session and document the insights gained during the process for future reference. This can be used as a future point of reference for problem solving activities.

Mastering the art of problem-solving is crucial in today’s complex and fast-paced environment. The 8D Problem-Solving methodology offers a structured, team-based approach to tackling challenges that can arise in any sector, be it manufacturing, public services, or logistics. This guide has walked you through each of the eight disciplines, offering best practices and highlighting common pitfalls to avoid. We’ve also enriched your understanding through real-world case studies that demonstrate the methodology’s versatility and effectiveness. Remember, the strength of 8D lies not just in identifying and resolving problems, but also in preventing their recurrence through systemic improvements. By adhering to the principles and steps outlined in this guide, you’re well on your way to becoming an adept problem solver, capable of driving continuous improvement in your organization.

8D Problem Solving Process

Solving major problems in a disciplined way.

By the Mind Tools Content Team

(Also known as Global 8D Problem Solving)

When your company runs into a major problem, you need to address it quickly. However, you also need to deal with it thoroughly and ensure that it doesn't recur – and this can take a lot of effort and elapsed time.

The 8D Problem Solving Process helps you do both of these seemingly-contradictory things, in a professional and controlled way. In this article, we'll look at the 8D Problem Solving Process, and we'll discuss how you can use it to help your team solve major problems.

Origins of the Tool

The Ford Motor Company® developed the 8D (8 Disciplines) Problem Solving Process, and published it in their 1987 manual, "Team Oriented Problem Solving (TOPS)." In the mid-90s, Ford added an additional discipline, D0: Plan. The process is now Ford's global standard, and is called Global 8D.

Ford created the 8D Process to help teams deal with quality control and safety issues; develop customized, permanent solutions to problems; and prevent problems from recurring. Although the 8D Process was initially applied in the manufacturing, engineering, and aerospace industries, it's useful and relevant in any industry.

The eight disciplines are shown in figure 1, below:

Figure 1: The 8D Problem Solving Process

The 8D Process works best in teams tasked with solving a complex problem with identifiable symptoms. However, you can also use this process on an individual level, as well.

Applying the Tool

To use the 8D Process, address each of the disciplines listed below, in order. Take care not to skip steps, even when time is limited; the process is only effective when you follow every step.

Discipline 0: Plan

Before you begin to assemble a team to address the problem, you need to plan your approach. This means thinking about who will be on the team, what your time frame is, and what resources you'll need to address the problem at hand.

Discipline 1: Build the Team

You should aim to put together a team that has the skills needed to solve the problem, and that has the time and energy to commit to the problem solving process.

Keep in mind that a diverse team is more likely to find a creative solution than a team of people with the same outlook (although if outlooks are too diverse, people can spend so much time disagreeing that nothing gets done).

Create a team charter that outlines the team's goal and identifies each person's role. Then, do what you can to build trust and get everyone involved in the process that's about to happen.

If your team is made up of professionals who haven't worked together before, consider beginning with team-building activities to ensure that everyone is comfortable working with one another.

Discipline 2: Describe the Problem

Once your team has settled in, describe the problem in detail. Specify the who, what, when, where, why, how, and how many; and use techniques like CATWOE and the Problem-Definition Process to ensure that you're focusing on the right problem.

Start by doing a Risk Analysis – if the problem is causing serious risks, for example, to people's health or life, then you need to take appropriate action. (This may include stopping people using a product or process until the problem is resolved.)

If the problem is with a process, use a Flow Chart , Swim Lane Diagram , or Storyboard to map each step out; these tools will help your team members understand how the process works, and, later on, think about how they can best fix it.

Discovering the root cause of the problem comes later in the process, so don't spend time on this here. Right now, your goal is to look at what's going wrong and to make sure that your team understands the full extent of the problem.

Discipline 3: Implement a Temporary Fix

Once your team understands the problem, come up with a temporary fix. This is particularly important if the problem is affecting customers, reducing product quality, or slowing down work processes.

Harness the knowledge of everyone on the team. To ensure that each person's ideas are heard, consider using brainstorming techniques such as Round Robin Brainstorming or Crawford's Slip Writing Method , alongside more traditional team problem solving discussions.

Once the group has identified possible temporary fixes, address issues such as cost, implementation time, and relevancy. The short-term solution should be quick, easy to implement, and worth the effort.

Discipline 4: Identify and Eliminate the Root Cause

Once your temporary fix is in place, it's time to discover the root cause of the problem.

Conduct a Cause and Effect Analysis to identify the likely causes of the problem. This tool is useful because it helps you uncover many possible causes, and it can highlight other problems that you might not have been aware of. Next, apply Root Cause Analysis to find the root causes of the problems you've identified.

Once you identify the source of the problem, develop several permanent solutions to it.

If your team members are having trouble coming up with viable permanent solutions, use the Straw Man Concept to generate prototype solutions that you can then discuss, tear apart, and rebuild into stronger solutions.

Discipline 5: Verify the Solution

Once your team agrees on a permanent solution, make sure that you test it thoroughly before you fully implement it, in the next step.

• Conducting a Failure Mode and Effects Analysis (FMEA) to spot any potential problems.
• Using Impact Analysis to make sure that there will be no unexpected future consequences.
• Using Six Thinking Hats to examine the fix from several different emotional perspectives.

Last, conduct a Blind Spot Analysis to confirm that you and your team haven't overlooked a key factor, or made an incorrect assumption about this solution.

Discipline 6: Implement a Permanent Solution

Once your team reaches a consensus on the solution, roll your fix out. Monitor this new solution closely for an appropriate period of time to make sure that it's working correctly, and ensure that there are no unexpected side effects.

Discipline 7: Prevent the Problem From Recurring

When you're sure that the permanent solution has solved the problem, gather your team together again to identify how you'll prevent the problem from recurring in the future.

You might need to update your organization's standards, policies, procedures, or training manual to reflect the new fix. You'll likely also need to train others on the new process or standard. Finally, you'll need to consider whether to change your management practices or procedures to prevent a recurrence.

Discipline 8: Celebrate Team Success

The last step in the process is to celebrate and reward your team's success . Say "thank you" to everyone involved, and be specific about how each person's hard work has made a difference. If appropriate, plan a party or celebration to communicate your appreciation.

Before the team disbands, conduct a Post-Implementation Review to analyze whether your solution is working as you thought, and to improve the way that you solve problems in the future.

In the late 1980s, Ford Motor Company developed the 8D (8 Disciplines) Problem Solving Process to help manufacturing and engineering teams diagnose, treat, and eliminate quality problems. However, teams in any industry can use this problem solving process.

The eight disciplines are:

• Build the Team.
• Describe the Problem.
• Implement a Temporary Fix.
• Identify and Eliminate the Root Cause.
• Verify the Solution.
• Implement a Permanent Solution.
• Prevent the Problem From Recurring.
• Celebrate Team Success.

The 8D Problem Solving Process is best used with a team solving complex problems; however, individuals can also use it to solve problems on their own.

What is 8D? A template for efficient problem-solving

How you respond when problems arise is one of the most defining qualities of a manager. Luckily, there are tools you can use to master problem-solving. The 8D method of problem-solving combines teamwork and basic statistics to help you reach a logical solution and prevent new issues from arising.

You’ve spent months overseeing the development of your company's newest project. From initiation, planning, and execution, you’re confident this may be your best work yet.

Until the feedback starts rolling in.

There’s no sugar-coating it—things don’t always go as planned. But production or process issues are hardly a signal to throw in the towel. Instead, focus on honing your problem-solving skills to find a solution that keeps it from happening again. 

The 8D method of problem solving emphasizes the importance of teamwork to not only solve your process woes but prevent new ones from occurring. In this guide, we’ll break down what 8D is, how to use this methodology, and the benefits it can give to you and your team. Plus, get an 8D template to make solving your issue easier. 

What is 8D?

The eight disciplines (8D) method is a problem-solving approach that identifies, corrects, and eliminates recurring problems. By determining the root causes of a problem, managers can use this method to establish a permanent corrective action and prevent recurring issues. 

How do you use the 8D method?

The 8D method is a proven strategy for avoiding long-term damage from recurring problems. If you’re noticing issues in your workflow or processes, then it’s a good time to give this problem-solving method a try. 

To complete an 8D analysis, follow “the eight disciplines” to construct a statistical analysis of the problem and determine the best solution.

The eight disciplines of problem-solving

8D stands for the eight disciplines you will use to establish an 8D report. As you may notice, this outline starts with zero, which makes nine total disciplines. The “zero stage” was developed later as an initial planning stage. 

To illustrate these steps, imagine your organization experienced a decline in team innovation and productivity this past year. Your stakeholders have noticed and want to see changes implemented within the next six months. Below, we’ll use the 8D process to uncover a morale-boosting solution.

D0: Prepare and plan

Before starting the problem-solving process, evaluate the problem you want to solve. Understanding the background of the problem will help you identify the root cause in later steps. 

Collect information about how the problem has affected a process or product and what the most severe consequences may be. Planning can include:

Gathering data

Determining the prerequisites for solving the problem

Collecting feedback from others involved

If we look back at our example, you may want to figure out whether this decline in morale is organization-wide or only applies to a few departments. Consider interviewing a few employees from different departments and levels of management to gain some perspective. Next, determine what knowledge and skills you will need to solve this lapse in productivity. 

D1: Form your team

Create a cross-functional team made up of people who have knowledge of the various products and workflows involved. These team members should have the skills needed to solve the problem and put corrective actions in place. 

Steps in this discipline may include:

Appointing a team leader

Developing and implementing team guidelines

Determining team goals and priorities

Assigning individual roles

Arranging team-building activities

From our example, a solid team would consist of people with first-hand experience with the issues—like representatives from all departments and key people close to workshop-level work. You may also want to pull someone in from your HR department to help design and implement a solution. Most importantly, make sure the people you choose want to be involved and contribute to the solution.

D2: Identify the problem

You may have a good understanding of your problem by now, but this phase aims to break it down into clear and quantifiable terms by identifying the five W’s a and two H’s (5W2H):

Who first reported the problem?

What is the problem about?

When did it occur and how often?

Where did it occur (relating to the sector, supplier, machine, or production line involved)?

Why is solving the problem important?

How was the problem first detected?

How many parts/units/customers are affected?

Use your team’s insights to answer these questions. From our example, your team may conclude that: 

Employees feel overwhelmed with their current workload. 

There is no real structure or opportunity to share new ideas.

Managers have had no training for meetings or innovation settings.

Disgruntled employees know they can achieve more—and want to achieve more—even if they seem disengaged.

Once you answer these questions, record an official problem statement to describe the issue. If possible, include photos, videos, and diagrams to ensure all parties have a clear understanding of the problem. It may also help to create a flowchart of the process that includes various steps related to the problem description.

D3: Develop an interim containment plan

Much like we can expect speedy first aid after an accident, your team should take immediate actions to ensure you contain the problem—especially if the problem is related to customer safety. 

An interim containment plan will provide a temporary solution to isolate the problem from customers and clients while your team works to develop a permanent corrective action. This band-aid will help keep your customers informed and safe—and your reputation intact.

Because your findings revealed workers were overworked and managers lacked training, your team suggests scheduling a few mandatory training sessions for leaders of each department covering time and stress management and combating burnout . You may also want to have a presentation outlining the topics of this training to get key managers and stakeholders interested and primed for positive upcoming changes. 

D4: Verify root causes and escape points

Refer back to your findings and consult with your team about how the problem may have occurred. The root cause analysis involves mapping each potential root cause against the problem statement and its related test data. Make sure to test all potential causes—fuzzy brainstorming and sloppy analyses may cause you to overlook vital information. 

In our example, focus on the “why” portion of the 5W2H. You and your team identify six root causes:

Managers have never had any training

There is a lack of trust and psychological safety

Employees don’t understand the objectives and goals

Communication is poor

Time management is poor

Employees lack confidence

In addition to identifying the root causes, try to pinpoint where you first detected the problem in the process, and why it went unnoticed. This is called the escape point, and there may be more than one. 

D5: Choose permanent corrective actions

Work with your team to determine the most likely solution to remove the root cause of the problem and address the issues with the escape points. Quantitatively confirm that the selected permanent corrective action(s) (PCA) will resolve the problem for the customer. 

Steps to choosing a PCA may include:

Determining if you require further expertise

Ensuring the 5W2Hs are defined correctly

Carrying out a decision analysis and risk assessment

Considering alternative measures

Collecting evidence to prove the PCA will be effective

Your team decides to roll out the training used in the interim plan to all employees, with monthly company-wide workshops on improving well-being. You also plan to implement meetings, innovation sessions, and team-coaching training for managers. Lastly, you suggest adopting software to improve communication and collaboration. 

D6: Implement your corrective actions

Once all parties have agreed on a solution, the next step is to create an action plan to remove the root causes and escape points. Once the solution is in effect, you can remove your interim containment actions.

After seeing success with the training in the interim phase, your stakeholders approve all of your team’s proposed PCAs. Your representative from HR also plans to implement periodic employee wellness checks to track employee morale .

To ensure your corrective action was a success, monitor the results, customer, or employee feedback over a long period of time and take note of any negative effects. Setting up “controls” like employee wellness checks will help you validate whether your solution is working or more needs to be done. 

D7: Take preventive measures

One of the main benefits of using the 8D method is the improved ability to identify necessary systematic changes to prevent future issues from occurring. Look for ways to improve your management systems, operating methods, and procedures to not only eliminate your current problem, but stop similar problems from developing later on.

Based on our example, the training your team suggested is now adopted in the new manager onboarding curriculum. Every manager now has a “meeting system” that all meetings must be guided by, and workloads and projects are managed as a team within your new collaboration software . Innovation is improving, and morale is at an all-time high!

D8: Celebrate with your team

The 8D method of problem-solving is impossible to accomplish without dedicated team members and first-class collaboration.

8D report template and example

Check out our 8D report template below to help you record your findings as you navigate through the eight disciplines of problem solving. This is a formal report that can be used as a means of communication within companies, which makes for transparent problem-solving that you can apply to the entire production or process chain.

Benefits of using the 8D method

The 8D method is one of the most popular problem-solving strategies for good reason. Its strength lies in teamwork and fact-based analyses to create a culture of continuous improvement —making it one of the most effective tools for quality managers. The benefits of using the 8D method include: 

Improved team-oriented problem-solving skills rather than relying on an individual to provide a solution

Increased familiarity with a problem-solving structure

A better understanding of how to use basic statistical tools for problem-solving

Open and honest communication in problem-solving discussions

Prevent future problems from occurring by identifying system weaknesses and solutions

Improved effectiveness and efficiency at problem-solving

Better collaboration = better problem solving

No matter how good a manager you are, production and process issues are inevitable. It’s how you solve them that separates the good from the great. The 8D method of problem solving allows you to not only solve the problem at hand but improve team collaboration, improve processes, and prevent future issues from arising.

What is the 8D Problem Solving? And How to use the 8D Report?

The 8D problem-solving process (also known as the 8 Disciplines) is very different from previous processes we explored previously, such as the Double Diamond process or the IBM Design Thinking. The 8D process works in a rigid standardised nature to address the crisis caused by problems. The 8D process aims to walk with the team to highlight the problem, its root causes and propose a long-term solution. The process is documented in an 8D report which includes details of each of the eight stages. At the end of this article, we will explore an example report, and you can find a free 8D report template to download.

In times of crisis, companies face the challenge of analysing and solving problems efficiently in a short time to save developed projects. Problem-solving techniques such as the  TRIZ method  and  Hurson’s Production Thinking Model  allow companies to overcome crises and solve problems using less effort and time.

Brief History of the 8D Problem Solving

The 8D method was first implemented by the US government during WW II as a military standard and was referred to as the Army Directive 1520, “Remedies and disposal of nonconforming materials.” In 1987, the demand for a team-oriented problem-solving method increased among the management organisation in the automotive industry to find a way to eliminate recurring issues.

Ford Motor Company published their manual,  Team Oriented Problem Solving (TOPS),  which includes their 8 Disciplines of the problem-solving process. The process was initially used to deal with quality control and safety issues inside the company but later expanded its role to a team approach problem-solving method. The 8D process is employed by engineers and designers to identify, analyse, and correct problems by eliminating the primary source that caused the problem.

So, what are the eight steps in the 8D methodology? The 8D problem solving process includes 8 Disciplines. In the mid-90s, a D0 step for planning was added to the process. The 8D steps include the following:

• D1: Team formation
• D2: Describe the problem
• D3: Develop a temporary containment plan
• D4: Determine and verify root causes
• D5: Verify the permanent solution
• D6: Implement the permanent solution
• D7: Prevent recurrence
• D8: Congratulate your team

The 8 Disciplines aim to achieve the following targets while solving the specified problem:

• Think as a team while solving the problem
• Isolate the situation and understand its causes
• Identify the factors that contribute to the problem
• Provide a temporary solution to halt the impact of the problem
• Eliminate the causes of the problem and the factors contributing to it
• Prevent the problem from recurring

When Should the 8D Problem Solving be Used?

Based on the above targets, the 8D problem solving process is designed for complex problems whose solution exceeds the ability of one expert. Also, it aims to establish communication for problem resolution through different levels inside the company. In some situations, the consumer or the management team requests the application of the 8D process through several forms or documentation.

While 8D problem solving is suitable for recurring problems that may repeatedly occur within a project or company, it is not ideal for simple issues that can be solved quickly by individual efforts. The process is unsuitable for a problem that can be solved with a straightforward solution. The 8D process is designed for complex issues, which require several weeks to solve and the involvement of at least four people.

8D problem solving provides a systematic process to find and solve problems. Therefore, if the situation requires choosing between alternative solutions, 8D acknowledges that other tools may help solve the problem better than the 8D process.

How to Apply the 8D Problem Solving Process?

The steps below form the 8 Discipline process to achieve targeted problem solving through the eight steps.

This discipline is also known as the Pre 8D because it aims to understand the problem and determine if the 8D process is the correct method to use. At this stage, the team aims to answer general questions such as:

• Is this a new problem, or has it happened before?
• Is this a recurring problem?
• What is the history of this issue?
• What was the method used to solve the problem before?

At this stage, the target is to learn about the problem’s history and decide if the 8D process is the best tool to solve the problem.

D1: Team Formation

Thinking as a team can produce more efficient solutions than trying to solve a problem alone. The team includes all the stakeholders involved in the situation. The team communicates with each other and performs brainstorming to solve the problem (check  Design Thinking Tools: Reverse Brainstorming ). If the team does not know each other, the brainstorming time can be used to learn how to teach members to explore ideas together. Methods can be used in brainstorming sessions such as mind mapping , Six Thinking Hats , and  Lego Serious Play.

D2: Describe the Problem

After team formation, the second step is to understand the problem and its risks. This stage starts with a risk analysis to identify the situation and how it can affect the project flow. Several methods can be used to analyse the problem from different perspectives, including  SWOT analysis ,  SCAMPER technique , and similar tools. This stage is essential to building a clear vision of the problem and ensuring all stakeholders have the same understanding of the situation.

D3: Develop a Temporary Containment Plan

While solving the problem, there should be a temporary containment plan to prevent the problem from affecting the rest of the project or the final product. This temporary containment solution is a short-term operation such as adding more labour, increasing the quality measurements, applying a risk plan, etc.

It is essential to understand that the containment action is not the real solution and can only be used for the short term. Therefore, this action can be applied internally and not affect the process of reaching a permanent solution.

D4: Determine and Verify Root Causes

This stage aims to investigate the root causes of the problem; it can be considered the core of the 8D problem solving process. In many problems, what we see as causes are symptoms of other root causes. This misunderstanding can lead to inaccurate attempts at solutions that can have negative consequences in the future and leave the underlying problem unsolved.

An intensive investigation should be implemented because, in many cases, the root cause is hidden inside the process and covered by many symptoms, which is confusing. Some tools can be used to define the root causes of the problem, such as  brainstorming , statistical analysis, flow charts, audits, etc.

D5: Verify the Permanent Solution

Once the root cause is defined, the solution becomes apparent, and the team better understands how to solve the problem. However, the symptoms and other related factors may create difficulties deciding how best to apply the solution. So, these other factors should be considered when determining the permanent solution to the dilemma.

When choosing the permanent solution to the problem, it should meet the following criteria to ensure it is the ideal solution for the problem:

• The solution should be practical
• The solution should be feasible
• The solution should be cost-effective
• The solution should not fail during production
• The solution should be implemented in all affected facilities in the company

D6: Implement the Permanent Solution

Once the solution is approved, this step tends to work as an action plan. This plan aims to outline the steps to implement the solution. It is common to ask questions in this stage: What should be done? Who should be involved in the correction plan?

More documentation and detailed plans should be created if the solution is complex and needs further procedures. The method may include training the team and checking the plan’s progress for further development and improvement.

D7: Prevent Recurrence

Once the action plan is set and ready to be implemented, the team should establish a plan to prevent the problem from occurring in the future. The action plan should be tested and documented as part of the process to avoid the recurrence of the problem. Some of the tools that can achieve this goal are Control Charts, Capabilities Analysis, and Control Plans.

D8: Congratulate the Team

After completing the task and implementing the solution, the team deserves an acknowledgement of their work and a celebration. This event will positively impact the stakeholders and reflect recognition of employees’ efforts from the management inside the company.

How do you Write an 8D Report?

The primary documentation used in the problem solving process is the 8D report. Korenko et al. (2013) presented an example of the 8D problem-solving application, Application 8D Method For Problems Solving . After this example, you can find a free 8D Report template that you can download and use for both commercial and noncommercial applications. The first part of the report, D0, includes information about the problem and the project details related to the project. D1 section contains details of the team involved in the project, roles, titles and contact information. D2 part of the report includes a detailed description of the problem and possible visual images to show the problem clearly. The report can consist of the type of damage of the failure and the function where the problem occurs (Figure 2).  

D3 includes details of the temporary solution for the problem required to stop the damage rapidly. In this part, the temporary remedy is described, particularly the symptoms affect, the responsibility, and the validation of the action. In D4, the team uses a root-cause method such as the 5WHYs or the Cause-Effect analysis (Fish Bone method). These methods help the team to identify the root causes of the problem. In Figure 3, the 5WHYs method is used several times to identify the root cause of the problem. 

D5 of the report provides details about the permanent solution to fix the problem. Unlike the temporary solution, this aims to element the root causes of the problem. This section includes the procedure’s name, the reason to use it, the responsibility, the management approval to apply it and the expected date of completing the utilisation of the solution, as seen in Figure 4. In the following stage, D6, the team provides details on the implementation and validation of the permanent action.

D7 provides details about preventing the recurrent problem, such as the name of the action after the validation process in the previous stage. Also, this stage provides details of the cause behind this action and elements about its responsibility and implementing details. Finally, in D8, the report includes a summary of the procedure and the proper approvals related to the procedure implementation (Figure 5).

You can download the below 8D report, which you can use for commercial and noncommercial projects. Don’t forget to mention Designorate as the source of this free 8D report.

The 8D Problem Solving process provides a reliable and systematic method that ensures that the problems inside a company or project are solved by eliminating their root causes and preventing recurrence. However, it is most suitable for complex problems that can take weeks or even months to solve. Therefore, the first stage aims to determine if the 8D process is ideal for the problem or if more straightforward tools should be implemented. If the 8D problem solving method is appropriate for your business problem, you have a step-by-step template to guide you through your attempts to find a suitable solution to the obstacle you need to overcome.

It’s easy to feel overwhelmed by the number of different approaches to problem solving. Some of the most common ones are PDCA , DMAIC , A3, 6S , Agile , 5 Whys , fishbone diagrams , and others. In this article, we’ll look at the 8D process for problem-solving and process improvement. We will present the benefits of 8D along with some best practices and an example of how to use it. This will provide you with some practical applications for use in your own organization.

Overview: What is the 8D process? 

The history of 8D is somewhat controversial. While everyone seems to agree that the popularity of the approach can be credited to Ford Motor company, the basis of the process is a little less clear. Senior leadership at Ford saw the need for the Powertrain division to have a methodology where teams could work on recurring problems. 

In 1986, work began to develop a manual and training course that would create a new approach to solving engineering design and manufacturing problems. The title of this manual was Team Oriented Problem Solving (TOPS), and it was first published in 1987. But where did the original idea come from?

Many give credit to the U.S. War Production Board, which developed a simple, four-step approach in 1945 for improving job methods. Here’s what they looked like.

Image source: allaboutlean.com .

In reality, the 8D process is officially known as the Eight Disciplines of Problem-Solving. To make things a little more confusing, it’s really nine steps. While originally developed as 8 steps or disciplines, it was subsequently revised to include a step zero, which was to plan and prepare for solving the problem.

Image source: ASQ.org .

Let’s provide a little more detail for each step.

• D0 — Plan: Collect information and data on the problem symptoms. Decide what preparations will be needed to complete the 8D process. Decide whether you will need an Emergency Response Plan to minimize or mitigate the immediate impact of your problem on the customer.
• D1 — Create a team: Put together a cross-functional team consisting of a core group plus a selection of subject matter experts ( SMEs ). Be sure to provide everything the team will need to be successful, including any training needed to properly execute the process.
• D2 — Define and describe the problem: Using relevant data, describe the problem in as detail as possible. Be sure to focus on your problem at this point, not your solution.
• D3 — Contain the problem: Protect your customer by creating containment actions to prevent any further negative impact to them.
• D4 — Identify, describe, and verify root causes: You can use a multitude of tools such as the 5 Whys, fishbone diagrams, brainstorming , and others to identify potential root causes. Use data to validate your root causes.
• D5 — Choose corrective actions: Select the most appropriate actions to resolve and eliminate the root causes of your problem. 
• D6 — Implement and validate your corrective actions: Implement your recommended solutions and corrective actions, and continue to monitor to assure yourself that they actually solved your problem.
• D7 — Take preventative measures: Revise your systems to proactively try to prevent these and similar problems from arising in the future.
• D8 — Congratulate your team: Communicate the work of the team and celebrate their efforts.

3 benefits of the 8D process 

It goes without saying that removing problems, improving your process, and preventing future problems will provide many benefits to your organization. Here are a few.

1. Simple and effective 

The 8D process has been compared to the PDCA model. Like PDCA, 8D is structured, organized, and simple in concept. 

2. Drives you to the root cause 

By following the sequential steps, this process should lead you to the elimination of your problem and prevent it from arising again. 

3. Team approach 

The use of a cross-functional team composed of a core group of people working in the problem area as well as subject matter experts contributing on an as needed basis will give you the synergy of combined knowledge and experience that should lead you to a solution. 

Why is the 8D process important to understand? 

While simple in concept, there are a number of things you should understand that will make this process both effective and efficient.

Elimination of the root cause

If you understand and follow the 8D steps, you will be able to eliminate — or at least mitigate — the negative impact of your problem.

Discipline 

The 8D steps are sequential and build on each other. If you have the discipline to stay on track, you will optimize the use of the 8D process. 

Problem-solving tools 

8D is a process and methodology. You will need to understand the purpose of each step so you can apply the proper problem-solving tools in each step.  

An industry example of 8D

A consumer product company located in Mexico City was experiencing an increase in its delivery trucks returning without having made product deliveries to its customers. There did not seem to be an obvious reason or solution, so the president of the company chartered a team to look into the problem. He assigned the company’s Lean Six Sigma Master Black Belt to put together and facilitate a team and chose to use the 8D problem-solving methodology.

He followed the process by first having a planning and preparation meeting to lay out the plan for analyzing the problem. He suggested that some of the delivery supervisors go out into the field to see if they can observe any unusual conditions. They also collected some data and recorded their observations.

A vigorous brainstorming session ensued in which the team listed all the possible reasons the problem was occuring. These potential root causes were validated by the data that was collected and the observations of the supervisors. They discovered the trucks were coming back without delivering all of the product because the customers didn’t have enough money to pay for the product. These were very small customers who had to pay cash on delivery.

The question then became: Why didn’t they have enough money? The next root cause was that the trucks were arriving later in the day, after the customer had already paid for most of their other deliveries and thus had no money left. Why were the trucks arriving so late? Because they got stuck in traffic because they left the yard too late. Why were they leaving so late? Because they were loading the trucks and doing the paperwork in the morning.

Eventually, the team arrived at a solution that had the trucks loaded, prepped, and ready to go when the drivers arrived early in the morning. The result was a dramatic reduction in returned goods and a significant increase in cash flow. The president was confident that the use of the 8D process got them to the right solution quickly and efficiently.

3 best practices when thinking about the 8D process

Like most of the other problem-solving approaches, there are some recommended practices that will help you and your team be successful. Here are a few that will help you stay on track. 

1. Pick the best team that you can 

Don’t seek volunteers, but hand-select the best team members that are available. It will be their knowledge and expertise that will make the team successful. Likewise for the team facilitator or leader.

2. Take your time 

Don’t rush to solutions or what you think is the root cause of your problem. Thoroughly explore your problem so that the solutions that you eventually come up with will resolve the problem and prevent future occurrences. Think creatively.

3. Be specific about what your problem is

Use data to help you understand your problem. Don’t just rely on anecdotal stories or assumptions to decide the root cause of your problem.

Frequently Asked Questions (FAQ) about 8D

1. when should i use the 8d process.

Use this process when you’re trying to solve for safety or regulatory issues, increasing customer complaints, warranty costs (which indicate greater-than-expected failure rates), internal rejects, waste, scrap, and poor performance or test results.

2. Can the 8D process be used in non-manufacturing processes?

Yes. While the 8D process was developed in the manufacturing function of Ford Motor Company, it can just as easily be applied in any type of process or function where you are experiencing problems.

3. What is the difference between the 8D and 5D process? 

For a less complex problem, you may decide to use a 5D process. This simplified process will have you form a team, identify your problem, implement containment actions, identify the root cause, and implement corrective actions to eliminate the problem.

So, what is the 8D process? 

The 8D process, also known as the Eight Disciplines of Problem Solving, is a method developed at Ford Motor Company used to resolve problems. It is focused on product and process improvement. 

The purpose of 8D is to identify, correct, and eliminate recurring problems. It establishes a permanent corrective action based on a problem analysis and determination of the root causes. Although it was originally comprised of eight stages, or “disciplines,” it was later revised to nine to include a planning and preparation stage.

8D Chess: How to Use The 8 Disciplines for Problem Solving

Hospitals have developed something of a reputation for being rife with bad processes . When processes aren’t adequate, the result is an abundance of “workarounds”.

For example, when equipment or supplies are missing, a nurse might waste time running around searching for what is needed, and once the item is found, return to their previous duties.

One study indicates that nurses spend 33 minutes of a 7.5-hour shift completing workarounds that are not part of their job description.

This may well “put out the fire” so-to-speak, but really it is just a hastily applied band-aid that does nothing to treat the root cause of the problem.

More time is wasted and more problems will arise in the future because nothing has been done to prevent the initial problem from happening again.

Individual nurses are not at fault here; workplace culture often values expertise in the form of those who “get the job done”, which tends to pull against the notion of spending time building good processes (time in which the job is perhaps not “getting done”).

So how to approach the problem of problem solving ?

In a lean context, problem solving can be distilled into two simple questions:

• What is the problem and how did it happen?
• How can we make sure that it doesn’t happen again?

The 8D, or eight disciplines methodology, is a problem solving process – most likely one of the most widely used problem solving processes out there. It is used by many different countries, in many different industries, and many different organizations.

8D is designed to help you put out those fires, and make sure they don’t happen again.

In this article, I’ll introduce you to the 8D problem solving methodology and provide you with an outline of the basic process that you can hopefully apply in your own business, plus how you can enhance 8D with other tools and methodologies like Six Sigma , FMEA , and Process Street .

Here’s what I hope you’ll take away after reading:

• An understanding of the basics of 8D
• Advantages of using 8D
• The purpose and objectives of each phase of the 8D process
• An understanding of how to use 8D for problem solving
• How 8D works with other problem solving tools
• How you can use Process Street to maximize the potential of the 8D framework

Let’s begin with the origins of 8D – what is it, and where did it come from?

What is 8D?

8D (sometimes Global 8D or G8D) stands for eight disciplines, and is a problem solving methodology. It’s basically a process for understanding and preventing problems.

Much like how risk management seeks to take a proactive, preventative stance, 8D aims to gain insight into the root causes of why the problems happen, so they won’t happen again.

The 8D process involves eight (sometimes nine) steps to solve difficult, recurring problems. It’s a transparent, team-based approach that will help you solve more problems in your business.

8D origins: Where did it come from?

Despite the popular story that 8D originated at Ford, it was in fact developed in 1974 by the US Department of Defence, ultimately taking the form of the military standard 1520 Corrective Action and Disposition System for Nonconforming Material .

Ford took this military standard, which was essentially a process for quality management , and expanded on it to include more robust problem solving methods.

In 1987, Ford Motor Company published their manual, Team Oriented Problem Solving (TOPS) , which included their first iteration of the 8D methodology.

Initially termed Global 8D (or G8D) standard, it is currently used by Ford and many other companies in the automotive supply chain.

8D, PDSA, & other problem solving processes

The disciplines of 8D follow the same logic as the Deming Cycle (also known as PDSA, and sometimes PDCA).

PDSA stands for Plan, Do, Study, Act (or Check, in the case of PDCA).

The similarity lies in the fact that both PDSA and 8D are designed to be used to improve processes. They’re both examples of cycles of continuous improvement.

Whereas 8D may be painted as a more generic problem-solving framework, structurally speaking both 8D and PDSA share a lot in common.

The simple idea of beginning with a clear objective, or desired output, and then testing, analyzing , and iteratively tweaking in a continuous cycle is the basis for both methodologies.

There are, of course, differences. We’ll cover the different applications of both 8D and PDSA in this article.

8D advantages

One of the main strengths of 8D is its focus on teamwork. 8D philosophy encourages the idea that teams, as a whole, are more powerful than the sum of the individual qualities of each team member.

It’s also an empirical methodology; that is to say that it is a fact-based problem solving process.

A branch of continuous improvement, proper use of 8D will help you coordinate your entire team for effective problem solving and improved implementation of just about all of the processes used in your business.

The 8 disciplines for problem solving

As you may have noticed, we’re starting with zero, which makes nine total disciplines. This “zero” stage was developed as an initial planning step.

D0: Plan adequately

Make comprehensive plans for solving the problem including any prerequisites you might determine.

Be sure to include emergency response actions.

D1: Establish your team

Establish your core team with relevant product or process knowledge. This team will provide you with the perspective and ideas needed for the problem solving process.

The team should consist of about five people, from various cross-functional departments. All individuals should have relevant process knowledge.

A varied group will offer you a variety of different perspectives from which to observe the problem.

It is advisable to establish team structure, roles, and objectives as far ahead in advance as possible so that corrective action can begin as quickly and effectively as possible.

D2: Describe the problem

Have your team gather information and data related to the problem or symptom. Using clear, quantifiable terms, unpack the problem by asking:

D3: Contain the problem (temporary damage control)

Depending on the circumstances, you may need to mobilize some kind of temporary fix, or “firefighting”.

The focus of this stage should be on preventing the problem from getting worse, until a more permanent solution can be identified and implemented.

D4: Identify, describe, and verify root causes

In preparation for permanent corrective action, you must identify, describe, and verify all possible causes that could contribute to the problem happening.

You can use various techniques for this, including a Failure Modes and Effects Analysis , or Ishikawa (fishbone) diagram .

It’s important that the root causes are systematically identified, described in detail, and promptly verified (or proved). How each cause is verified will depend on the data type and the nature of the problem.

Take a look at the section towards the end of this article for some more problem solving tools to help you decide the right approach.

D5: Identify corrective actions

You must verify that the corrective action you identified will in fact solve the problem and prevent it from happening again in the future (or whatever is your desired threshold of recurrence).

The best way to do this is to collect as much data as possible and by performing smaller-scale “pilot” tests to get an idea of the corrective action’s impact.

You can’t begin to identify the optimal corrective action until you have identified the root cause(s) of the problem.

D6: Implement and validate corrective actions

Carry out the corrective actions, and monitor short and long term effects. During this stage, you should assess and validate the corrective actions with empirical evidence.

Discuss and review results with your team.

D7: Take preventative measures (to avoid the problem happening again)

Here is where you make any necessary changes to your processes, standard operating procedures , policies , and anything else to make sure the problem does not happen again.

It may not be possible to completely eliminate any chance of the problem recurring; in that case, efforts should focus on minimizing possibility of recurrence as much as possible.

D8: Congratulate your team

It’s important to recognize the joint contribution of each and every one of the individuals that were involved in the process.

Team members should feel valued and rewarded for their efforts; this is crucial and perhaps the most important step – after all, without the team, the problem would not have been fixed.

Providing positive feedback and expressing appreciation helps to keep motivation high, which in turn improves the sense of process ownership and simply increases the likelihood your team will actually want to improve internal processes in the future.

How to use 8D for problem solving

The 8D method above outlines a proven strategy for identifying and dealing with problems. It’s an effective problem solving and problem prevention process.

In addition to avoiding long-term damage from recurring problems, 8D also helps to mitigate customer impact as much as possible.

More than just a problem-solving methodology, 8D sits alongside Six Sigma and other lean frameworks and can easily be integrated with them to minimize training and maximize efficacy.

8D is definitely a powerful framework on its own, but it really shines when combined with other synergistic concepts of lean and continuous improvement.

More problem solving tools that synergize well with 8D

8D has become a leading framework for process improvement, and in many ways it is more prescriptive and robust than other more simplistic Six Sigma approaches.

However, there are many Six Sigma methodologies, and even more frameworks for problem solving and process improvement .

The following improvement tools are often used within or alongside the 8D methodology.

DMAIC: Lean Six Sigma

DMAIC stands for:

The DMAIC process is a data-driven cycle of process improvement designed for businesses to help identify flaws or inefficiencies in processes.

Simply put, the goal with DMAIC is to improve and optimize existing processes.

Interestingly, the development of the DMAIC framework is credited to Motorola , whose work built upon the systems initially developed by Toyota .

In terms of working alongside 8D, you could use DMAIC to identify root causes as in D4; you could also implement the same techniques to better understand prospects for corrective actions as in D5, and D6.

We have a whole article on the DMAIC process, if you’re interested.

SWOT analysis

Strengths, Weaknesses, Opportunities, and Threats. You can use a SWOT analysis to gain insight into your organization as a whole, or on individual processes.

The main synergy with 8D is in the identification of opportunities, threats, and weaknesses.

These can represent opportunities for process improvements, weaknesses in your process that could produce problems further down the line, and threats, both internal and external, that may be out of your direct control but that could cause problems for you.

Here’s a SWOT analysis checklist you can use to structure your own analysis:

FMEA: Failure Mode and Effects Analysis

FMEA (Failure Mode and Effects Analysis) is a way of understanding the potential for problems and making preemptive preparations in order to avoid them. It is a method of risk management .

It is a type of preventative risk management process, and so works well in the context of identifying causes of problems so you can better deal with them.

FMEA and 8D work well together because:

• 8D can make use of information gathered during an FMEA process, like brainstorming sessions, to identify potential problems and their root causes.
• You can reuse possible cause information gathered during an FMEA process to feed into different representational diagrams like the Ishikawa (fishbone) diagram, which will help in the 8D process.
• 8D brainstorming data is useful for new process design. This allows the FMEA to take actual process failures into account, which produces more effective results.
• FMEA completed in the past can be used as databases of potential root causes of problems to inform 8D process development.

Here’s a free FMEA template for you to get started ASAP:

The Pareto Chart

The Pareto Chart helps us understand the impact of different variations of input on our output.

In relation to 8D, Pareto Charts can help us prioritize which root cause to target, based on which will have the greatest impact on improvement (where improvement is the desired output of the 8D process).

Here’s the Six Sigma Institute’s example Pareto Chart :

Here we have a simple deductive reasoning technique that asks “why?” five times to dig into the root cause of a problem.

The logic here is that by asking the same question five times, you work progressively “deeper” into the complexity of the problem from a single point of focus.

Ideally, by the fifth question you should have something that has a high likelihood of being a root cause.

This example from Wikipedia does a great job of conveying how the process works:

• The vehicle will not start. (the problem)
• Why? – The battery is dead. (First why)
• Why? – The alternator is not functioning. (Second why)
• Why? – The alternator belt has broken. (Third why)
• Why? – The alternator belt was well beyond its useful service life and not replaced. (Fourth why)
• Why? – The vehicle was not maintained according to the recommended service schedule. (Fifth why, a root cause)

Ishikawa diagrams (fishbone diagrams)

Sometimes called “cause-and-effect diagrams”, they are as such used to visualize the cause and effect of problems.

The approach takes six different categories and places information about the problem into different categories to help you understand what factors could be contributing to the problem.

One advantage over the 5 Whys approach is the way this method forces a more holistic perspective, as opposed to the potentially narrow vantage point offered by zooming in on a single aspect or question.

According to the Six Sigma Institute, the 6 key variables pertaining to root causes of problems are:

• Machine: Root causes related to tools used to execute the process.
• Material: Root causes related to information and forms needed to execute the process.
• Nature: Root causes related to our work environment, market conditions, and regulatory issues.
• Measure: Root causes related to the process measurement.
• Method: Root causes related to procedures, hand-offs, input-output issues.
• People: Root causes related people and organizations.

There’s also this useful illustration of a company using a fishbone diagram to better understand what factors contribute to a company’s high turn around time.

Gap analysis

A gap analysis is concerned with three key elements:

• The current situation, or “performance”
• The ideal situation, or “potential”
• What needs to be done in order to get from performance to potential, or “bridging the gap”

The “gap” is what separates your current situation from your ideal situation.

Businesses that perform a gap analysis can improve their efficiency and better understand how to improve processes and products.

They can help to better optimize how time, money, and human resources are spent in business.

There’s a lot that goes into a gap analysis, and quite a few different ways to approach it. Check out our article for a deeper dive into the gap analysis process.

8D Problem Solving: Comprehensive Breakdown and Practical Applications

The 8D problem-solving process stands as a beacon of structured analysis and corrective action within the complexities of operational pitfalls and quality control discrepancies across industries. Originating from the automotive industry and since adopted widely, the methodology offers a meticulous step-by-step approach that fosters team cohesion, addresses problems at their roots, and implements sustainable solutions.

This article seeks to delve into the nuances of the 8D problem-solving framework, presenting a lucid exposition of its origins, a detailed foray into each step enriched by practical examples, and concluding with the unequivocal benefit bouquet it presents to the organization adopting it.

The Origins of the 8D Problem Solving Methodology

The 8D, or "Eight Disciplines," problem-solving approach germinated from the fertile grounds of collaborative efforts to ensure superior quality and reliability in manufacturing. Initially developed by the Ford Motor Company in the 1980s, this systematic method was a response to a confluence of quality and operational issues that were pervasive in the automotive industry. It drew broader appeal as its efficacy became apparent - functioning as an amalgam of logic, analytics, and teamwork to tackle problems methodically.

The wide reach of the 8D methodology is evident in industries ranging from manufacturing to healthcare, aerospace to IT, and beyond. Its universal applicability stems from a foundational adherence to principle over process, transcending the intricacies of industry-specific challenges. By combining reactive and proactive measures, the 8D method helps in not just extinguishing the fire, but also preventing its outbreak, making it an enduring asset in the organizational toolkit.

The 8 Steps of Problem Solving

An incursion into the 8D methodology reveals a framework that is both systematic and flexible. Each step is sequenced to ensure that issues are not merely patched but genuinely resolved, implementing robust preventive measures to curtail recurrences. This section expounds on each disciplinary step and serves as a substrate for practical implementation examples, supplementing theoretical insights with real-world applicability.

Step 1: Establish a Team

The cornerstone of any formidable 8D approach begins with assembling a competent team. The wisdom embedded in this initial phase is the recognition that effective problem-solving is not a solitary venture but a collaborative pursuit. A multidisciplinary team brings diverse perspectives that are critical in diagnosing issues accurately and devising solutions effectively.

When determining team composition, the emphasis should be on a mix of skills and expertise relevant to the problem at hand. Roles within the team should be clearly defined to streamline activities and foster accountability. Each member should be well-versed in their responsibilities, from those leading the problem-solving charge to those executing and tracking actions.

Step 2: Describe the Problem

Clarity is vital in the second step, which necessitates delineating the problem with precision. A meticulous description sets the foundation for targeted analysis and actionable solutions. It involves accruing information that is factual, quantifiable, and devoid of assumptions – the cornerstone of an accurate problem portrayal.

Techniques like '5W2H' (who, what, when, where, why, how, how much) can galvanize teams into crafting detailed problem descriptions. An exemplar of a well-articulated problem statement might state, "Machine X has experienced a 15% decline in output quality, resulting in a monthly loss of 200 units of product Y since January due to recurrent mechanical inaccuracies."

Step 3: Develop Interim Containment Actions

Addressing a problem's immediate impact is pivotal to prevent exacerbation as a root cause analysis is conducted. Interim containment actions can be likened to first aid – essential, though not the definitive cure. These measures should be rigorously designed to quell the problem's spread or intensification without creating new issues.

An interim action for the aforementioned issue with Machine X could involve adjusting the production schedule to mitigate output loss while the machine is under examination. This demonstrates a temperate solution, buying time for a comprehensive fix without severely disrupting the production chain.

Step 4: Define and Verify the Root Cause(s)

Singular in its focus yet pluralistic in its approach, this phase is committed to uncovering the underlying reasons for the problem. Root cause identification is a task of surgical precision, necessitating a deep dive into the problem without the constraints of predetermined notions.

Techniques such as the "5 Whys" and "Fishbone Diagram" guide problem solvers through a structured investigation of potential causes. Verification is as crucial as identification, ensuring that purported root causes stand up to scrutiny and testing.

Step 5: Verify Permanent Corrective Action(s)

Once root causes have been established, attention shifts to devising and validating long-term corrective actions. This step traverses the path from theory to practice. It requires a judicious appraisal of potential solutions with a clear-eyed view of their feasibility, effectiveness, and sustainability.

Best practices in this step incorporate piloting solutions on a smaller scale, enabling refinement before full-scale implementation. A well-considered corrective action for Machine X might involve upgrading mechanical components identified as failure points, subject to cost-benefit analysis and potential disruption to the production line.

Step 6: Implementing and Validating Permanent Corrective Actions

This step transitions the plan into reality, pushing the corrective actions beyond the threshold into the operational environment. Careful implementation is the linchpin, with detailed plans and schedules ensuring that actions are well-executed and efficacious.

The validation process is a keystone in affirming that corrective actions deliver the intended improvements. For Machine X, this could entail monitoring post-repair performance metrics over a defined period against pre-issue levels to authenticate the efficacy of the improvements.

Step 7: Preventive Measures

Armed with insights gleaned, the 7th step propels the methodology into preventative mode. Here, the onus is on forestalling a problem’s resurgence by ingraining the lessons learned into the organizational fabric. The aim is to encapsulate these insights in policies, procedures, or system changes.

This could mean revising maintenance schedules or worker training programs for Machine X to include the specific nuances that led to the mechanical inaccuracies, thereby shielding against repeat episodes.

Step 8: Congratulate Your Team

The final step encompasses a human-centered focus on recognition and commendation. Acknowledgment of the team’s efforts reinforces motivation, fosters a positive culture, and encourages engagement in future problem-solving initiatives.

Celebrating the success could manifest in a ceremonious recognition of the team’s achievements, an internal announcement of their contributions, or a tangible expression of appreciation. This not only cements the accomplishment but also propels a sense of camaraderie and collective purpose.

The Importance of the 8D Problem Solving Process

A mature consideration of the 8D problem-solving process corroborates its contributory significance in unraveling complex issues and instituting consequential improvements. The benefits it confers are manifest in enhanced product quality, heightened customer satisfaction, and the stimulation of a proactive problem-solving culture. Challenges do persist, mainly in the form of resistance to change or insufficient training; nevertheless, with a conscientious implementation, these can be navigated.

Moreover, the 8D approach aligns seamlessly with the pursuit of continuous improvement – a cornerstone of many business philosophies such as Lean and Six Sigma. It thus serves not only as a solution framework but also as a catalyst for organizational growth and learning.

In summary, the 8D problem-solving methodology stands out for its disciplined, team-driven, and methodical approach to tackling complex problems. From its historical roots in the automotive industry to its implementation in modern enterprises, its efficacy in achieving sustainable solutions is undoubted. Online certificate programs and problem-solving courses often feature 8D due to its relevance and value across industries.

As this article delineates each step, with practical applications and advice, the message is clear: mastery of 8D is not just for immediate problem resolution – it is a pathway to building a resilient and adaptive organization capable of facing the challenges of an ever-changing business landscape.

What are the Eight Disciplines of Problem Solving (8D)?

The Eight Disciplines of Problem Solving (8D) is a systematic, holistic and proven methodology designed to identify the root cause of a problem, plan a quick fix, and implement corrective actions and preventive actions to avoid their recurrence. If your product is defective or not meeting your customer requirements, then 8D is an excellent first step to improve Quality and Reliability.

8D has become very popular among manufacturers, assembly, and services around the globe because it is effective and comparatively easy to teach.

Why Apply Eight Disciplines of Problem Solving (8D)

The 8D methodology, developed to represent the best practices in problem-solving, provides the engineering teams with an effective and efficient team-oriented problem-solving skill, a better understanding of Root Cause Analysis (RCA) and how to use basic statistical tools required for problem-solving. 8D helps the management understand and resolve problems better, identify necessary systemic changes and inputs for change , and facilitate a more candid and open communication in problem-solving discussions.

8D improves the Quality and Reliability of your products, and if performed correctly, prepares the engineering team for future problems.

When to Apply Eight Disciplines of Problem Solving (8D)

The 8D problem-solving process is used to solve major, critical, chronic, and recurring problems. The 8D is typically required during safety or regulatory issues, customer complaints , warranty concerns, poor performance or test failures, internal rejects, and to minimize waste and scrap.

How to Use Root Cause Analysis to Transform Your Safety Program

How to apply eight disciplines of problem solving (8d).

The 8D is a systematic process for the introduction and improvement of quality, and elimination of problems. Here we will show you the step by step approach of the problem-solving tools that can make you proficient at identifying causes of problems, defining problems, and errors. Additionally, it helps identify root causes and take actions to solve and prevent identified problems in processes. So, let’s take a peep inside:

D0: Planning and preparing for the 8D

Proper planning and preparation are always a good start before taking any action. So, you need to consider the following before forming a team:

• Problem description
• Timeframe for the resolution
• The number of resources to accomplish this

D1: Team establishment

Create a team with people who varied backgrounds and experiences which will lead to the best quality inputs and a complete solution. For the team to function smoothly, define clear roles, and responsibilities for your people, and have a team leader.

D2: Problem description

The 8D method’s primary focus is to describe the problem appropriately and objectively such that it captures all the vital information. During this analysis, repeated 5W1H (why, what, who, where, when, and how) are required to be asked to develop a clear description.

D3: Problem containment plan

A temporary problem containment plan is sometimes needed to minimize the impact of the problem until you develop permanent solutions. On developing the plan based on the hypothetical cases, the resources for addressing the main problem can be released. At times, new processes may be required to work around the problem until you have a permanent fix.

D4: Root Cause Analysis (RCA)

With the problem temporarily contained, you can now turn to identify all of the root causes of the nonconformance . There are several tools to identify the actual root cause of an issue including the 5W1H to understand the problem in-depth, Fishbone diagrams to visually categorize causes, and Pareto charts to identify the vital causes.

D5: Permanent Corrective Action

Once the root cause of the problem is determined, the team can start brainstorming permanent corrections to identify what the best long-term solution will be. Brainstorming sessions combined with tools such as affinity diagrams help organize ideas based on their relationships and determine the best course of action.

D6: Implement and Validate the Permanent Corrective Action

Once the solution is identified, the management needs to implement and verify the corrective action using the PDCA (plan-do-check-act) approach for small-scale testing before large-scale rollout. Thus, the outcomes and corrective actions are tracked to ensure expected results. To successfully implement a permanent change, a project plan should incorporate:

• Development of the project plan for implementation
• Communicating the plan to all stakeholders
• Validating improvements using measurement

D7: Prevent Recurrence

A complete solution of problems means preventing them from occurring. Besides, preventative measures should also be implemented for corrective actions in the 8D methodology. This requires reviewing management processes, operating procedures, and training manuals to ensure that best practices are followed.

At this stage, organizations should consider actions including updating process audit questions and regularly verifying them based on corrective actions to reduce risk in other processes, presenting poka-yoke or error-proofing devices to big-risk processes, and conducting red rabbit tests to see how long it takes poka-yoke devices to detect defective product.

D8: Verification and Team Celebration

Once the problem is solved, the ultimate step is to congratulate the team. It’s important to recognize their efforts and share their success across the organization because teams require feedback to allow for satisfactory closure. This facilitates motivation and employee engagement while helping you improve quality control, execute process improvements, and aid change management as you grow.

Create a team with people who are having varied backgrounds and experiences which will lead to the best quality inputs and a complete solution. For the team to function smoothly, define clear roles, and responsibilities for your people, and have a team leader.

A complete solution of problems means preventing them from occurring initially. Besides, preventative measures should also be implemented for corrective actions in the 8D methodology. This requires reviewing management processes, operating procedures, and training manuals to ensure that best practices are followed.

8D and Root Cause Analysis (RCA)

Root Cause Analysis (RCA) is embedded within the 8D process and includes the following steps and techniques:

Problem Symptom is measured and transformed to “Object and Defect”

Problem Symptom is reformed to Problem Statement using the 5W1H process

Potential Causes are gathered using the tools like Fishbone or Affinity Diagram

Problem Statement should fit using both the “is” and the “isn’t” sections of the question

Root Cause concepts are developed from remaining possible causes on the tool and related changes from is/is not

Compare theories with recent data and develop experiments for Root Cause Verification

Test and confirm the Root Causes

8D Problem-Solving Report

8D problem-solving reports and templates are useful tools to initiate a problem-solving process. These reports are used to explain what 8D is and including information about each step so that one will know what needs to be done by attempting this to solve problems. Keeping these reports easily available can avoid repeating work on the same problems over and over again.

8D reports must be detailed and incorporate information at every step within the 8D process. Those who are working on the problem should provide sufficient information when completing a report so that someone who was not on the current 8D team can pull it out and understand what the problem was and what solutions were implemented.

Who Can 8D Help?

The 8D methodology is universally applicable for every organization that needs solving. Although, there are a few industries and sectors where this 8D approach is successfully used such as manufacturing, the automotive idustry, engineering companies that manufacture products or parts, and medium and large-scale enterprises.

What is 8D(Eight Disciplines)?

8D stands for eight disciplines (8D) model. It is a problem-solving approach typically employed in the automotive industry by quality engineers. But it has also been successfully applied in healthcare, retail, finance, government, and manufacturing.

8D is a problem-solving methodology, useful for finding a short term fix and permanent solution to your product or process problems.

It provides structure to the problem-solving process.8D methodology gives a hollistic approach to problem-solving. It covers containment till prevention of problem recurrence.

Moreover, this tool can be used as a part of continuous improvement of any product or process.

The purpose of the 8D methodology is to identify, correct, and eliminate recurring problems.

The 8D problem-solving model helps establish corrective and preventive action to avoid problems in the future.

8D method was first used as a part of  Team Oriented Problem Solving (TOPS) in the United States during world war-2.

8D Methodology was made popular by Ford in 1990s. It was used for all problem-solving activities. It helped standardize the problem-solving process throughout the automotive industry.

Although this method was originated by the US military, generally it is referred that Ford originated it, since they used it on such a large scale and made it popular.

The 8D method is also known as Global 8D , Ford 8D or TOPS 8D .

8D Methodology follows the PDCA approach.D1 to D5 is covered under the planning phase, D6- constitutes Do phase, D7 and D8 constitute check and act phase.

T HINGS TO CHECK BEFORE IMPLEMENTING 8D METHODOLOGY

• Nature of the problem. Is it a new problem or a chronic one?
• Is it a repetitive problem? if yes what problem-solving methodology was used and why it failed?
• Checking the complete history of the problem.

8D PROBLEM-SOLVING METHODOLOGY

8D methodology consists of 8 steps or 8 Disciplines. It helps provide structure to our problem-solving process.

Due to its certain sequence, it helps inculcate multiple perspectives.

Also, this process helps back our actions with statistical data. The 8D Report consists of 8 disciplines that describe corrective measures based on the statistical analysis of the problem.

D1-Create a Team

Building a relevant team is the first step to this problem-solving process. The team should be multidisciplinary. It should include all departments like Production, Development, Quality, etc.

Combination of multiple experiences, skill set, and knowledge base helps take the multidimensional perspective of the problem in hand.

Somebody should be adopted as a team leader. Because the team without captain means, everybody is captain, which creates chaos and hampers the process.

Roles and desirable outputs of each member have to be clearly defined. It makes the process effective. Defining roles and expectation in advance makes the process quicker and more efficient.

Who should be on the 8D team?

The appropriate size of the 8D team is 4 to 8 people who are closely related to the problem. It usually involves people from different functions/departments in the organization coming together to solve a common problem.

• A champion is a sponsor, not an active working member. He is responsible for proving final approval for changes if he agrees with findings.
• A team leader (i.e. Quality engineering or Product Manager) – The person who coordinates the entire 8D project through-out all of its 8 disciplines. Team leader act’s as a binding force amongst all team members.
• An 8D expert (i.e. Quality Engineering) – A person who has the technical know-how of the 8 disciplines. He/she guides the team for appropriate implementation of 8D methodology.
• A subject expert is one who has the domain expertise.He/she is expert in the domain to which problem belongs. Example casting expert.
• Supporting Functions (i.e. Supplier Quality, Electrical Engineering, Mechanical Engineering, Manufacturing Engineering, Operations, Field Service, Technical Support, Marketing, Application Engineering, etc…) – people who have practically experienced the problem and understand the pain it causes.

Key responsibilities of team leader

• The team leader must define the roles of each team member and bring it on paper.
• The team leader must schedule meetings periodically to review the progress of the 8D project and discuss activities related to any delays. All meetings should be documented. Minutes of the meeting must include agenda, actions decided, responsibility, target date.

D2-Describe Problem

Well-defined problems lead to breakthrough solutions. Organizations need to become better at asking the right questions so that they tackle the right problems.

Define the problem as objectively as possible. A clear description of the problem helps the team come up with more relevant solutions.

Communicate the scope of the problem that the team is working on and get the team focused.

What to define at this stage

• Monetary limits.
• Expectation and deliverables from the team.

Tools used at this stage

• Data collection for background information (is/is not analysis).
• Pareto charts.

D3-Containment Action

Containment action is like first aid. You try to avoid worsening of the wound. Containment action is like temporary action or a quick fix till team works on permanent action.

For example, if you receive a customer complaint in a particular part. Your first response would be to stop all supplies or production of that particular part. You would check all the material at the customer end, at your plant or in-transit for any defect.

It would not solve the issue permanently but would provide a temporary fix.

Why containment action is important

• Problem-solving is a time-consuming activity. Containment is important to avoid further production of defective parts and dispatch to the customer.
• Containment guarantees limitation of risk and warranty claims.

Check Points for this stage

• Effectiveness of containment action.
• Never allow an interim containment action to cover the gravity of the problem thus reducing the need for a permanent solution
• Additional problems are not generated by the implementation of containment actions.
• Relative cost benefits of containment actions should be tested.

D4 – Identify the root cause

Once the problem has been contained, the next step is to find out the root cause. Why it occurred?

Brainstorming sessions are arranged to find out all the possible causes. An important aspect of brainstorming is that no filters are there during brainstorming sessions.

Defining the root causes of a problem is the core of the 8D problem-solving process. This is normally the toughest aspect of the problem-solving process; if the root causes of the problem were obvious, then the problem would have been solved already.

• Pareto Charts
• Affinity Diagram
• Brainstorming Session
• 5-Whys Process
• Fishbone Diagram
• Fault Tree Analysis
• Statistical Analysis
• Regression Analysis
• Hypothesis Testing
• Flow Charts
• Root cause identified is not just a symptom. Make sure the symptom is not cured in the illusion of root cause.
• Make sure the root causes found fit both the “is” and the “isn’t” sections of the question.
• The root cause is simulated, to verify the effect.

D5 – Permanent corrective actions

Any problem can have multiple root causes. In this step, we provide permanent corrective actions for one or more root causes identified in the previous step.

Corrective action is an action to eliminate the cause of a detected nonconformity.

It’s important at this stage, to define what is the corrective action? When it has to be implemented? Who will implement it? Where to implement? How it would be implemented?

Defining what, when, who, where and how brings objectivity to this process. It keeps everyone involved accountable.

Criteria for choosing the best solution

• The solution is practical. The team should be able to implement it.
• It is feasible.
• The solution is cost-effective.
• It is robust. The solution shouldn’t fail when used in production. Robustness of the solution is an essential characteristic.
• Team champion agrees with it.
• The solution is first to be tried on small lots to validate that it has indeed solved the problem prior to full implementation.

Checkpoints for this stage

• Resources required for the implementation of the solution are easily available.
• Supplier capacity is sufficient to produce tighter specs if required.
• ROI(Return on investment) is positive.
• The solution can be implemented within the deadline.
• Training is provided.

D6 – Implement Permanent corrective actions

In this step, we implement the corrective actions derived in the previous step.

We implement corrective action and check its effectiveness. If action is not effective we repeat D4 and D5. The process repeats until the action taken is not effective.

The statistical tools such as process capability, histograms, control charts, etc. can be used to measure and verify the effectiveness of the implemented corrective actions.

Our goal at this step is to verify if actions taken are solving the problem effectively or not?

• The action plan is laid out on paper. Tools like Gantt Chart, PERT can be used for planning.
• All procedures have been laid out for action implementation.

D7 – Prevent Recurrence

In this step, we take preventive measures to avoid recurrence of the problem. Prevention is better than cure, hence implementing systems which avoid recurrence of problems is an important aspect of the problem-solving process.

Preventing the problem from recurring requires analyzing design, operation, and management system in minute details.

We make changes in design(product or process), operation system and management system to avoid problem repetition.

We need to horizontally deploy actions to similar sections(Where ever applicable). It involves standardization of systems to incorporate changes as a part of the system.

Checkpoint for this stage

• Actions taken are validated.
• Action plan results are documented.
• Corresponding standard documents are updated.
• All controls for the solution are put in place.
• Control charts
• Control plans
• Capability Analysis

D8 – Congratulate Team

Conducting this whole drill without the team is close to impossible. Once the process has been completed and results are available in measurable form.

We need to appreciate each member of the team for there efforts and reward them for their contribution.

Appreciating work of team members, instill a feeling of participation in team members and make them feel important. This kind of acts helps uplift team morale.

All the above seven steps won’t be sustainable without this last step. So its super-duper important.

WHY USE 8D METHODOLOGY?

8D Methodology has been popular amongst engineering teams as it provides a clear cut, easy to learn approach for problem-solving. It helps reach better solutions because of its inherent structured approach.

I have listed down benefit 8D methodology offers :

• It helps provide a structure for our problems solving process.
• Its has become a global standard, so everyone understands it well.
• It brings order to chaos.
• The fast and effective methodology of problems solving.
• It helps document the process.
• Instills a feeling of self-worth in the team due to active participation in the process.
• Defining steps in advance, avoid chances of skipping any part of the process.
• It is easy to learn and implement.
• Provides a practical understanding of Root cause analysis(RCA).
• Since it uses a team approach, multiple perspectives are taken into consideration before reaching a conclusion.

8D problem-solving tool not only helps solve current problems but also make us future-ready.

The following improvement tools are often used within the 8D methodology:

• Ishikawa diagrams (Cause and Effect diagrams, C&E diagrams or Fishbone diagrams)
• Pareto charts or Pareto diagrams
• 5W and 2H (Who, What, Where, When, Why, How, How often)
• Statistical Process Control (SPC)
• Scatter plots or scatter diagrams
• Design of Experiments (DOE)
• Check sheets
• Histograms or Capability Analysis
• Failure Modes and Effects Analysis (FMEA)
• Flowcharts or Process Maps

WHEN TO USE 8D METHODOLOGY?

The 8D approach is used to solve critical, major, chronic and recurring problems.

The 8D use is typical when:

• The problem complexity exceeds the ability of one person (an expert) to resolve the problem.
• Communication of the problem resolution (during & after) must go across company levels, other departments and/or to customers. The same solution can be applied to multiple areas.
• The customer requests for submission of 8-D.

However, the 8D is not effective for

• Non-recurring problems or problems which can be solved quickly by individual effort.
• Problems with known root causes.
• To choose between different alternative

8D Process: Its Importance and Advantages

The 8Ds — also known as the 8 Disciplines — Problem Solving Process is a team-oriented methodology that is mainly used to identify, correct, and eliminate recurring problems.

The methodology focuses on the origin of a problem by determining the root cause and establishes a permanent corrective and preventive action accordingly. It is an 8 tier process with integrated basic problem-solving tools.

This article will help you looks at 8D best practices how it can be helpful for manufacturers to better understand tools and techniques to address nonconformances and reduce risk.

History of 8D Problem Solving Process

There was a dire need for a team-oriented problem-solving strategy based on the use of statistical methods of data analysis. Ford Motors during World War II were manufacturing war vehicles in bulk. To ease up the assembly lines and the entire management in general, the executives of Powertrain Organization wanted a methodology where teams could work on recurring problems.

In 1986, the assignment was given to develop a manual and a course that will teach a new approach to solving tough engineering design and manufacturing defects. The manual for this methodology was documented and defined in “Team Oriented Problem Solving (TOPS)”, published in 1987.

The manual and courses were led at World Headquarters in Dearborn, Michigan. Subsequent changes and revisions were made based on the feedback from pilot sessions. The materials were extensive and the 8D titles were mere chapter headings for the steps in the process. Ford also refer to their current variant of the 8D process as G8D (Global 8D)

Use of 8D Process in Military

The US Government recognized the full caliber of the 8D process. During World War II, they standardized a process as Military Standard 1520 “Corrective Action and Disposition System for Non-confirming Materials”

Their 8D process was used to identify, correct, and eliminate recurring problems, whilst the methodology was useful in product and process improvement. It established a permanent corrective action based on a statistical analysis of the problem. It also focused on the origin of the problem by determining the root cause. 

The 8D approach

The 8D model establishes a permanent corrective action based on statics and data of the problem. It focuses on the origin of the problem by determining its root causes. The earlier 8D models comprised of eight stages, the model got changed as time progressed. It was later expanded by an initial planning stage.

The stages (or Disciplines) are as follow:

D0 — Plan adequately

Proper planning and preparation is of utmost necessity before taking any action. So, before forming a team for the project, you’ll need to consider the following:

• Problem description
• Timeframe of the task
• Amount of resources

D1 — Establish your team

Create a diverse team with extensive portfolios. Make sure they have enough experience so that they can lead to the best quality inputs and complete solutions. For teams to function smoothly, define clear roles and responsibilities.

D2 — Describe the problem

The 8D methodology focuses on describing a problem objectively, capturing every vital information. During the analysis, a loop of 5W1H (why, what, who, where, when, and how) should be applied to develop a clear problem description.

D3 — Contain the problem

Projects that are big and take days to run a single task on them require a temporary problem containment plan to minimize the impact of a problem until a permanent solution is found. On developing the plan based on hypothetical cases, the resources for addressing the main problem can be released.

D4 — Identify the root cause

When the problem is temporarily contained, you can work on identifying the root cause of the nonconformance. You can use the 5W1H framework to understand the problem in-depth, or the Fishbone diagrams to categorize visually, or Pareto Charts to identify the vital causes.

D5 — Identify corrective actions

Once the root cause is recognized, the team can start brainstorming permanent corrections to identify the best long-term solution. Brainstorming with the team along with taking help from tools like affinity diagrams can help in organizing ideas.

D6 — Implement and validate corrective actions

Once a solution is identified, the management needs to implement and verify the corrective action. The PDCA (plan-do-check-act) approach is beneficial in this stage to do small-scale testing. To successfully implement a permanent change, a project plan should incorporate:

• Project plan development for implementation
• Communication of the plan with stakeholders
• Validating improvements using measurements

D7 — Implement preventive actions

A complete solution always provides no reoccurrence of problems. Even if you have created a complete solution, you should still work on preventive measures (after all, better today than tomorrow!).

In this stage, teams must consider actions that include updating audit process questions and verifying corrective actions periodically to reduce risk in processes. Teams can utilize the Poka-Yoke/Error Proofing methodologies to run tests to find defects.

D8 — Recognize team and individual efforts

At the end of the day, everyone wants their work to be recognized. Don’t be shy about that. Celebrate the team’s success and congratulate individuals for their work contribution. Doing such will facilitate motion and employee engagement while helping the organization to improve quality control.

Six Sigma tools that synergize with 8D

8D has become one of the leading frameworks for process improvement. It is robust and can mix easily with other prominent methodologies such as Six Sigma.

The following are improvement tools often used in Six Sigma processes. Learn how the addition of 8D can improve the process even further.

DMAIC – Lean Six Sigma

The DMAIC process is a data-driven cycle for process improvement. It is designed for businesses to identify flaws, errors, defects, or inefficiencies in a process.

Learn more on DMAIC and the process here .

In terms of combining 8D:

• One can use DMAIC to identify the root cause as in step D4
• One can implement the same technique to better understand prospects for corrective actions in steps D5 & D6

FMEA – Failure Mode & Effects Analysis

FMEA helps in understanding the potential for problems and making preemptive preparations to avoid them. This methodology is used majorly by Risk Management teams.

FMEA & 8D:

• 8D can use information gathered during an FMEA process to identify potential problems and the root causes. 
• The information gathered during the FMEA process can be reused to feed into representational diagrams like Ishikawa (Fishbone) diagram.
• 8D brainstorming data can be used for new design processes. This allows the FMEA to take actual failures into account, thus producing effective results.
• Database from previous FMEA can be used as a benchmark for root causes of the problem to inform on 8D process development.

Pareto Charts

Pareto charts are majorly used to analyze data on the frequency of problems/causes in a process. It helps in understanding the impact of different variations of input and outputs via data and graphical representation.

• In relation to 8D, Pareto charts help in prioritizing which root cause to target based on which will have the greatest impact on the improvement process.

The 5 Whys is a deductive reasoning technique that asks “Why?” five times. The logic here is to ask the same question (WHY?) over and over again, making the reasoning process dig deeper into the complexity of a problem from a single point of focus.

When someone reaches the “5th Why?”, they should have something that has a high likelihood of being a root cause.

Benefits of 8D Problem Solving

8D focuses on teamwork. The framework’s philosophy is to encourage teams as a whole and individually. It’s a pragmatic methodology, i.e. a fact-based problem-solving process. 

One of the main strengths of 8D is its focus on teamwork. 8D philosophy encourages the idea that teams, as a whole, are more powerful than the sum of the individual qualities of each team member.

Here are a few of the benefits that you can expect from the 8D problem-solving process:

• Institutes a structured and consistent problem-solving approach within an organization
• Enables individuals to become more effective at problem-solving
• Encourages team-based approach
• Helps ensure customers receive a timely and effective response to any concern
• Supports the requirements of quality management systems for corrective action, problem-solving, and continual improvement
• Helps in avoiding future problems by solving them in the present time
• Reduces Cost of Poor Quality (COPQ) by using the lessons learned in process improvement actions
• Assists organizations to comply with the customer-specific requirement for management concerns
