Fishbone Diagram Template – Free Ishikawa PDFs & Online Makers
A fishbone diagram (Ishikawa / cause-and-effect) is a classic root cause analysis tool. Put the problem at the “head,” then brainstorm causes along the “bones,” grouped by categories (often the 6Ms). Use the directory below to find printable Word/PDF templates or online editors.
Export Your Fishbone, Then Optimize It for Web
Fishbone templates often export as large PNG/PDF files. Use ImageConver to resize, crop, compress, and convert (PNG ⇄ JPG ⇄ WebP) so pages load fast and text stays readable.

How to Use a Fishbone Diagram (Simple Steps)
- Write the problem statement at the head (specific, measurable if possible).
- Choose categories (6Ms for manufacturing or service-friendly categories).
- Brainstorm causes for each category (add sub-causes as smaller branches).
- Ask “why?” repeatedly until causes are testable and specific.
- 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.
