8D: Explained

8D of problem solving

We have familiarized ourselves with the concept of 8D (eight disciplines of problem-solving). In this section, we will dive into the model and explore all its components. Here are the eight disciplines of problem-solving that will greatly help you enhance your business processes: 

D1: Establish the team

The first step in 8D is to assemble a team of individuals with the knowledge and skills to address the problem. This team should have multiple functions. This means the committee should include members from different departments or areas of expertise to provide a comprehensive view of the issue. The team leader is usually someone with experience in problem-solving methods.

Collaboration is key in this phase because the complexity of most problems requires input from various perspectives. You need to establish a capable team. This way, you can ensure that your company approaches the issue with a diverse range of insights and solutions.

D2: Describe the problem

In the second step, the team defines the problem in detail (problem statement). This includes describing its symptoms, scope, and impact on the business. The goal is to clarify what is wrong so your team can focus its efforts on solving it. It is essential to be specific, as vague problem descriptions can lead to ineffective solutions.

By using data and facts, your team can create a clear picture of the problem, which helps identify the root cause later. A well-defined problem sets the stage for successful analysis and resolution. It makes this step essential in the 8D process. Remember, describing the problem is halfway to solving a problem.

D3: Develop interim containment actions (ICA)

Once you define the problem, your team must implement temporary measures to contain its effects. These actions prevent the problem from worsening while you develop a permanent solution. Interim containment actions are crucial because they buy you time for a thorough investigation without letting the problem disrupt your business operations.

These actions are not the final fix but are necessary to keep things under control. Your team must ensure these measures are effective and do not introduce new issues. This maintains business continuity during the problem-solving process.

D4: Determine and verify the root cause

Step four of the 8D model involves identifying the root cause of the problem. Here, your team uses various tools and techniques, such as the 5 Whys or Fishbone diagram, to dig deeper into the issue and find the origin. Once you identify the root cause, you must verify it through data or testing.

Verification is vital to ensure your team has identified the actual cause, not just a symptom. By addressing the root cause, your team can create long-lasting solutions. It reduces the likelihood of the problem recurring. Accurate identification and certification are critical to the success of 8D.

D5: Choose and verify permanent corrective actions (PCA)

After identifying the root cause, your team develops permanent corrective actions to solve the problem. These solutions must be effective and sustainable. Once you identify the potential solutions, your team must test and verify them to ensure they truly eliminate the problem without causing unintended side effects.

Verification often involves testing the solutions in a controlled environment before full implementation. This step ensures that the corrective actions address the root cause and are viable in real-world applications. Effective permanent corrective actions are crucial for your business’s long-term success.

D6: Implement and validate permanent corrective actions (PCA)

In the sixth step, your team implements the verified corrective actions across all relevant areas of the business. Validation is the key here, confirming that your solution works as intended in real-world conditions. The team monitors the results to ensure that you have fully resolved the problem and that no new issues have arisen.

Proper implementation and validation are vital for making sure the problem does not occur again. This phase often involves training employees, updating procedures, and communicating the changes throughout the organization to ensure smooth execution.

D7: Prevent recurrence

Once you have validated the corrective actions, the focus shifts to preventing the problem from happening again. This involves updating company policies, procedures, or training programs to reflect the changes made. Your team may also recommend additional preventive measures based on lessons learned during the 8D process.

By embedding these changes into your company’s daily operations, you can create a culture of continuous improvement. Preventing recurrence is essential for maintaining long-term success and avoiding the same issues in the future.

D8: Congratulate the team

The final step in the 8D process is to recognize your team’s efforts. Celebrating success boosts morale and encourages employees to engage in future problem-solving initiatives. Acknowledging the hard work and collaboration that went into solving the problem is important. It fosters a positive and proactive work environment.

It also serves as a reminder of the importance of teamwork and structured problem-solving. This step helps close the loop on the process, reinforcing the value of 8D methodology and encouraging its continued use in your company.
