Analyze
Fishbone / Ishikawa
Explore possible causes, organize the evidence, and verify what drives the problem.
Analyze · Interactive CI tool
Root Cause Analysis Builder organizes a problem, branching hypotheses, evidence and validation records in one editable investigation.
Read freely. Creating a worksheet requires a verified free beta account. No payment or manual beta approval.
Use it when a problem has several possible explanations or needs a documented investigation across more than one branch.
It helps a team see competing explanations and distinguish a supported cause from a plausible story.
Use Fishbone for broad cause brainstorming or 5 Whys for a focused chain. Use a Control Chart when the first question is whether a time pattern is unusual.
Fictional example snapshot
A fictional business sees incorrect delivery dates on confirmations.
| Hypotheses | Stale template; manual override; delayed supplier information |
|---|---|
| Contradiction | Some errors occurred on the current template |
| Next test | Compare override records with the incorrect-date cases |
These figures illustrate the method; they are not clinical instructions, universal targets or verified results from a real organization.
