How to use the root cause fishbone diagram builder

  1. Name the problemType the issue you are investigating into the problem statement field.
  2. Label your categoriesAdjust the six category names if the defaults do not fit your situation.
  3. Add causes and exportAdd possible causes under each category, then export the finished diagram.

How to run a fishbone analysis

Start with a clearly worded problem statement at the head of the diagram, then work through each category asking "why might this contribute to the problem?" rather than jumping straight to a single culprit. Encouraging a team to fill in every category, even the ones that seem irrelevant at first, often surfaces contributing factors that a narrower discussion would have missed entirely.

Ask why five times

For any promising cause, keep asking why it happens to dig past the symptom toward the actual root cause.

Do it as a group

A fishbone diagram works best as a shared exercise, since different people usually spot different categories of causes.

Root Cause Fishbone Diagram Builder FAQ

What is a fishbone diagram used for?

It is a root-cause analysis tool that organizes possible causes of a problem into categories, so a team can look systematically for what might really be behind an issue instead of jumping to one explanation.

Can I rename the six categories?

Yes, edit any of the six category name fields above the diagram. The default names follow the common People, Process, Equipment, Materials, Environment and Management framework, but you can replace them with whatever fits your situation.

How many causes can I add per category?

As many as you like. Each one is added as a small labeled branch off that category's line.

Can I export the diagram?

Yes, use Download SVG for an editable vector file, or Download PNG for a standard image.
