About the 5 Whys template
The 5 Whys is a root cause analysis technique that traces a problem back to its underlying cause by asking "why?" repeatedly, typically five times, until you reach a systemic failure rather than a symptom. Originating at Toyota, it works because most defects and incidents stem from process or condition gaps, not one-off mistakes. Getting to the true cause lets you fix the source instead of firefighting recurring issues.

When to use a 5 Whys
- βΈInvestigating a defect, incident, or missed deadline that has a single clear problem statement
- βΈFacilitating a blameless post-incident or retrospective discussion
- βΈBefore writing corrective actions in a CAPA or audit response
- βΈQuick root cause work where a full fishbone or fault tree would be overkill
What a good 5 Whys includes
- βA precise problem statement describing what happened, when, and its impact
- βThe sequential why-answer chain, each building on the previous answer
- βThe identified root cause once the chain reaches a systemic factor
- βCorrective and preventive actions tied to the root cause
- βOwner and due date for each action
- βEvidence or data supporting each answer to avoid assumptions

Tips & common mistakes
- π‘Base each answer on verified facts, not opinions, so the chain doesn't drift into guesswork
- π‘Stop when you hit a process or system cause, not a person; blaming individuals hides the real gap
- π‘Five is a guideline, not a rule, follow the logic until the cause is actionable

FAQ
When should you stop asking why?οΌ
Stop when you reach a cause you can act on at the process or system level, and asking why again would only produce speculation. This is often before or after the fifth why, depending on the problem.
Can a problem have more than one root cause?οΌ
Yes. When answers branch, run a separate why chain for each path, since a single incident often has multiple contributing causes needing different corrective actions.
How is 5 Whys different from a fishbone diagram?οΌ
5 Whys follows one linear cause-and-effect chain, while a fishbone (Ishikawa) diagram maps many possible cause categories at once; the two are often used together for complex problems.
