What is 5 Whys?

It’s a technique where you ask “why” up to 5 times to get to the root of a problem.

The 5 Whys technique is a root cause analysis method. It helps uncover underlying issues behind surface-level problems by repeatedly asking "Why?" until you reach the origin. Originally developed by Toyota, it’s now widely used in Agile, DevOps, and retrospectives.

PMs use 5 Whys to debug bugs, failures, or churn — driving corrective action that addresses the source, not just symptoms.
