How to Use a Fishbone Diagram (Simple Steps)

  1. Write the problem statement at the head (specific, measurable if possible).
  2. Choose categories (6Ms for manufacturing or service-friendly categories).
  3. Brainstorm causes for each category (add sub-causes as smaller branches).
  4. Ask “why?” repeatedly until causes are testable and specific.
  5. Prioritize root causes to validate with data, experiments, or process checks.

Common Fishbone Categories (6Ms Cheat Sheet)

Manufacturing (6Ms)

  • People (Man): training, staffing, communication, fatigue
  • Machine: tooling, maintenance, calibration, wear
  • Method: SOP, workflow, handoffs, inspection steps
  • Material: suppliers, specs, storage, variability
  • Measurement: gauges, sampling, test method, bias
  • Environment (Mother Nature): temperature, humidity, layout, noise

Service / Software (Alternative)

  • People: roles, skills, load, incentives
  • Process: steps, approvals, queue time, SLAs
  • Tools: systems, integrations, outages, UX
  • Policy: rules, compliance, constraints
  • Data: inputs, quality, definitions, access
  • Environment: market, customer behavior, competition

Fishbone Diagram Template FAQ

Fishbone vs 5 Whys: which should I use?

Use a fishbone when there are many possible causes and you need categories to organize brainstorming. Use 5 Whys when you have a clear symptom and want to drill down a single cause chain.

What’s the best format for printing?

PDF is best for printing. Leave enough whitespace and keep labels short so teams can write clearly.

How do I keep fishbone text crisp on my website?

Export near your display size, avoid heavy compression, and prefer SVG when available. If you use PNG, convert to WebP with a high quality setting and preview at 100% zoom.
