About this document
5 Whys Analysis for Root Cause Investigation by Biswaranjan Kar is a document available to read on EtoBox.
The 5 Whys technique helps identify the root cause of problems by repeatedly asking "Why?". It can be used to investigate issues involving human factors. An example shows a worker losing a finger when it was pinched in unguarded machinery. Repeatedly asking "Why?" revealed that no hazard assessment was completed, which was the root cause. The 5 Whys helps differentiate root causes from contributing factors, determine relationships between root causes, and can be quickly learned without statistics.
