8D – Eight Disciplines of Problem Solving Process

Course Objectives

Participants can expect to learn and develop skills to confidently:

  • Perform 8D step by step
  • Link 8D to Failure Mode and Effects Analysis (FMEA), Product Development Process and Advanced Product Quality Planning (APQP)
  • Facilitate an effective 8D
  • Participate in 8D exercises
  • Define root causes and mechanisms of failure
  • Set up aCross Functional Team (CFT)
  • Determine effective Interim Containment Action
  • Manage and store 8D content (Lessons Learned) for future use
  • When to select and utilize tools such as:
    • 5 Why
    • Ishikawa/Fishbone
    • Affinity
    • Is / Is Not
    • Statistical Process Control (SPC)
    • Poka Yoke (Error Proofing)
  • Understand links to Control Plan Methodology
  • Complete the 8D format correctly
