Fishbone

Map possible causes and check the evidence.

How this works

See the possible causes. Follow the evidence.

Start here · Describe one observed problem at the head, then add possible causes to the branches or use the existing sample.

What you’ll get · An editable cause-and-effect diagram with hypotheses to investigate.

Check the method with a worked example

Separate observations from suspected causes. For each priority branch, record a safe evidence check and what result would weaken the hypothesis. A completed diagram is not proof.
