The 8D methodology mainly focuses on solving problems in eight steps. It helps quality control staff find the root cause of problems within a production process in a structured manner so that they can resolve problems.
Additionally, 8D helps implement product or process improvements, which can prevent problems.
The benefits of the 8D methodology typically include effective approaches to finding a root cause as well as developing proper actions to eliminate root causes, and implementing permanent corrective actions. The system also helps to explore the control systems that allowed the problem to “escape.”
The Escape Point is studied for the purpose of improving the ability of the Control System to detect the failure or cause when and if it should occur again. Yet another aspect of the 8D methodology, the Prevention Loop, explores the systems that permitted the condition that allowed the Failure and Cause Mechanism to exist in the first place.
The 8D approach is most commonly used by the automotive industry but has also been successfully applied in healthcare, retail, finance, government and manufacturing.
Because the purpose of the 8D methodology is to identify, correct and eliminate recurring problems, it is also useful in product and process improvement.
The eight disciplines methodology consists of eight stages (disciplines) as well as an initial planning stage:
- Create a Team
- Define and Describe the Problem
- Contain the Problem
- Identify, Describe and Verify Root Causes
- Choose Corrective Actions
- Implement and Validate Corrective Actions
- Take Preventive Measures
- Congratulation Your Team
