The 5 Whys Explained: Root Cause Analysis

In this video, we explain the 5 Whys method, a simple yet powerful tool for root cause analysis used in Lean Manufacturing, Six Sigma, and Continuous Improvement. Stop treating symptoms — start solving problems for good! What to Avoid 🚫 Don’t stop too early — shallow answers won’t solve the issue. 🚫 Don’t blame individuals — the point is system improvement, not blame. ✅ Always back up each “why” with real evidence. ✅ Use it for simple to moderately complex problems — and combine it with Fishbone Diagrams or FMEA for deeper analysis. Best Practices ✅ Keep your problem statement factual ✅ Involve the right people — not just leadership ✅ Document the chain of logic ✅ Validate the root cause before taking action ✅ Focus on systemic solutions, not quick fixes Done right, the 5 Whys leads to long-term improvement — not just short-term relief.
