5 Whys Analysis

Getting to the Root Cause of a Problem

5 Why’s Analysis is a problem solving tool designed to get to the heart of a problem. In theory, it is simple. Ask ‘Why’ something happened five times until you can’t come up with another underlying reason—hence the name, 5 Why’s Analysis.

One of the benefits of this problem solving tool is its simplicity. It can be learned in a matter of minutes, and can be taught by people fairly soon after learning it.

As simple as the tool is, there are some things to avoid when using it, and some tips to get more out of it. You can learn more from our 5 Whys enhanced term in The Continuous Improvement Companion.
