The Formula Explained
The 5 Whys technique involves asking "why" iteratively until reaching the root cause of a problem.
Glossary of Terms
- Problem: The initial issue that needs analysis.
- Why: A question asked to delve deeper into the problem's cause.
How It Works: A Step-by-Step Example
Consider a scenario where a machine stops working. By asking "why" five times, you may discover the root cause is a lack of regular maintenance.
