Steps to Conducting a Five Whys Analysis
-
1. Gather the Team
-
Invite all employees affected by the issue to participate in the analysis
-
2. Choose a Leader
-
Identify an individual to facilitate the process, guide the meeting and document all findings
-
3. Define the Problem
-
Agree on the specific definition of the problem that you have met to discuss. The leader should document the agreed definition.
-
4. Ask the First "Why"
-
The leader asks \'Why?\' the defined problem initially occurred. As a team, discuss and explore various avenues of thought.
-
5. Record the Answers
-
Record all answers no matter how obvious they seem. Discuss these answers and agree on the most likely systemic cause before moving to the next \'why\'.
-
6. Repeat for Each "Why"
-
Repeat the process of asking \'Why?\', where each iteration is questioning the answer to the previous \'Why?\'. Agree on a systematic cause at each level until you have reached a root cause. This should be clear when discussions no longer bring about productive or useful answers.
-
7. Agree on Corrective Actions
-
Review each question/answer combination and agree on the corrective action (if required), down to, and including, the level of the root cause.
-
The "Leader" assigns responsibility for each corrective action and documents this in the analysis.
-
8. Record and Share the Analysis
-
The leader documents and communicates the findings (including follow up actions) to the group involved in the discussion and any others affected by any of the proposed changes.
