01

Describe the problem

State what went wrong and where it happened. Add observations or attach a report so the causes can be grounded in the situation you are investigating.

02

Watch the bones fill in

The assistant places the problem at the head, groups possible causes along the spine and adds smaller branches for the details behind each cause.

What is a fishbone diagram?

A fishbone diagram groups possible causes of a problem around a central spine. Also called an Ishikawa or cause-and-effect diagram, it puts the problem at the head and cause categories on the bones.

When to use one

Delivery delays, product defects, customer complaints and recurring mistakes: use a fishbone to explore several explanations before choosing one to investigate. Use a 5 Whys diagram to follow one causal chain, or a Pareto chart to compare measured issue counts.

What a good fishbone diagram looks like

  1. One specific effect at the head, describing the observed problem rather than a proposed solution.
  2. Categories that fit the problem, such as equipment and materials for a production issue.
  3. Causes on the smaller bones, with each detail connected to the category it belongs to.
  4. Possible causes labeled as possibilities. A branch is an explanation to test, not proof.
  5. Concrete causes instead of blame, so each branch points to something you can investigate.

How MyMap builds it

The assistant reads your problem, suggests relevant categories and arranges possible causes along the fishbone on the canvas. Each cause label is editable. Use follow-up messages to expand a category and separate observations you supplied from explanations that still need evidence.

Common questions

Is the fishbone diagram maker free?

You can create a fishbone diagram and export it as PNG for free. PDF export is available with Pro.

Can I customize after generation?

Absolutely. Every cause, category, and branch is editable. You can add sub-causes, rename categories, or ask AI to expand any branch with a follow-up message.

What categories does the fishbone use?

Categories depend on the problem. Manufacturing diagrams often use People, Methods, Machines, Materials, Measurement and Environment. Ask for categories that fit your case, such as Product, Support and Pricing for customer churn.

What's the difference between a fishbone diagram and a root cause analysis?

A fishbone diagram is one specific tool within root cause analysis (RCA). RCA is the broader methodology; the fishbone diagram is a visual way to brainstorm and organize potential causes. Other RCA tools include 5 Whys and fault tree analysis.
