8D Problem Solving: A Permanent Fix in 8 Steps
A team-based, systematic method that fixes recurring problems at the root cause, not the symptom.
What is 8D?
8D (Eight Disciplines) is a team-based, systematic problem-solving method born in the automotive industry. The goal is to eliminate the root cause — not just the symptom — and prevent recurrence.
The 8 steps
- D1 · Build the team
- D2 · Define the problem
- D3 · Contain (interim action)
- D4 · Find the root cause
- D5 · Choose the permanent corrective action
- D6 · Implement and verify
- D7 · Prevent recurrence
- D8 · Recognize the team
When to use it
8D is ideal for recurring problems with an unclear root cause, especially customer complaints. It is most powerful combined with tools like Ishikawa and 5 Whys.
