What is 8D Problem Solving?

Although it is not one of the 5 “Core Tools”, many organizations (Ford Motor in particular) use this method in their operations. Eight Disciplines Problem Solving is a method used to approach and to resolve problems, typically employed by quality engineers or other professionals.

  • D0: The Planning Phase: Plan for solving the problem and determine the prerequisites.
  • D1: Use a Team: Establish a team of people with product/process knowledge.
  • D2: Define and describe the Problem: Specify the problem by identifying in quantifiable terms the who, what, where, when, why, how and how many (5W2H) for the problem.
  • D3: Developing Interim Containment Plan Implement and verify Interim Actions: Define and implement containment actions to isolate the problem from any customer.
  • D4: Determine and Identify and Verify Root Causes and escape points: Identify all potential causes that could explain why the problem occurred. Also identify why the problem has not been noticed at the time it occurred. All causes shall be verified or proved, not determined by fuzzy brainstorming.
  • D5: Choose and verify Permanent Corrective Actions (PCAs) for root cause and Escape point : Through pre-production programs quantitatively confirm that the selected corrective actions will resolve the problem for the customer.
  • D6: Implement and validate PCAs: Define and Implement the best corrective actions.
  • D7: Prevent recurrence: Modify the management systems, operation systems, practices and procedures to prevent recurrence of this and all similar problems.
  • D8: Congratulate your Team: Recognize the collective efforts of the team. The team needs to be formally thanked by the organization.[1][2]

8D has become a standard in the Auto, Assembly and other industries that require a thorough structured problem solving process using a team approach.
