3 Legged 5 Why

5 Why

  • By repeatedly asking the question "Why" (five is a good rule of thumb), you can peel away the layers of symptoms which can lead to the root cause of a problem. Actions may be applicable at different levels of the root cause. Action at root cause must be identified to prevent reoccurrence.

5 Why - Why did the problem occur?

  • Why 1 - Why did this occur?

  • Why 2 - Why did why 1 occur?

  • Why 3 - Why did why 2 occur?

  • Why 4 - Why did why 3 occur?

  • Why 5 - Why did why 4 occur?

  • Root Cause/Corrective Action:

  • Add media

5 Why - Why was the problem not detected?
