Problem solving

The Eight Disciplines (8D) is a problem solving method for product and process improvement. Its purpose is to identify, correct, and eliminate recurring problems. The structured approach provides transparency, drives a team approach, and increases the chance of solving the problem. 8D follows the logic of the PDCA-cycle. The disciplines are:

D1: Use a Team

Gathering together a good and cross-functional team is a crucial part. Due to a varied composition of knowledge, skills and experience, a problem can be looked at from different angles.

D2: Define and Describe the Problem

Define the problem in measurable terminology: Who, What, When, Where, Why, How, How Much (5W2H analysis). This is a good addition to the problem analysis and can help you to get a clear description of the problem.

D3: Develop an Interim Containment Plan

This may be necessary to temporarily solve the obstacle. For example, to help a customer quickly and meet their expectations, or because a deadline has to be met. Finding the definitive solution in that case is of later concern. The point is that the problem getting worse is prevented, but it does have the goal of implementing the final solution later.

D4: Determine and Verify Root Causes

Before a definitive solution is found, it is important to identify underlying causes that may be at the root of the problem. Use the 5 Whys and cause and effects diagrams to map causes against the effect or problem identified.

D5: Verify Permanent Corrections (PCs)

As soon as the cause of the problem is known, the best solution can be found. From here, permanent corrections can be chosen and checked to solve the problem. It is also important to check whether the chosen solutions have any unwanted side effects. That is why it is necessary to also develop emergency measures that come in handy for unexpected events.

D6: Implement and Validate Corrective Actions

As soon as the definitive solution is clear, you can start with the implementation. By scheduling recurring audits, with a solution like Qooling for example, underlying problems can be eliminated prematurely. You also need to monitor long-term effects and take unforeseen events into account.

D7: Prevent Recurrence / System Problems

Prevention is better than cure. Therefore, additional measures must be taken to prevent you from making the same type of problems in the future. Often it is best to carefully review management systems, operation systems and procedures, and change them where necessary.

D8: Congratulate Your Team!

Recognize the collective efforts of the team. Formally thank team members for their involvement. Use approaches that appeal to each individual member, as not every employee is the same. This is therefore the most important step within the 8D method. Because without the team, the problem could probably not be found and solved. Make sure you celebrate achievements.

The 8D method is a great method to not only reduce product and processing concerns, but also to increase customer satisfaction. A practical workflow solution like Qooling can help you with this in many ways. Experience the many possibilities of Qooling and ask for a free demo.
