Review draft
Your reviewable output appears here
The root cause fishbone diagram is generated only from the values you provide. No evidence, status, score, or approval is inferred.
- Load the fictional example to learn the exact input grammar.
- Replace it with one bounded set of approved facts and evidence references.
- Generate, inspect, download, then record the accountable decision elsewhere.
Product contract
Understand the root cause fishbone diagram before use
This contract states the real input grammar, deterministic transformation, output format, and human-decision boundary for this route.
What you need
Complete pipe-separated rows in the displayed schema, a bounded review scope, an accountable owner, and approved evidence references where applicable.
What you receive
A separately named nirmion_tools file containing a formula-safe CSV register. Download resets current fields; the latest three small outputs remain available in this tab for re-download.
Practical workflow
A defensible root cause fishbone diagram workflow
Use this route to organize possible causes by category with supporting or missing evidence and an investigation owner; the draft does not prove causation. It structures supplied facts; it does not execute tests, inspect systems, fetch evidence, or make a release, audit, or supplier decision.
Confirm the exact scope and period, applicable requirements, current evidence sources, decision criteria, accountable owner, and who must approve or escalate the final outcome.
Inspect every generated value and statement, resolve missing or conflicting evidence, record exceptions and approvals in the authorized system of record, then monitor agreed follow-up actions.
Each non-empty line must contain exactly 4 pipe-separated values. Empty cells, extra separators, more than 500 rows, or cells over 1,000 characters are rejected.
Decision boundary
A generated artifact is not proof of quality or approval
Do not treat this output as proof of product quality, compliance, safety, audit completion, root cause, or release readiness. Accountable quality, engineering, security, compliance, operations, and business owners must validate evidence and make the decision.
Pre-use checklist
Review before operational use
- Remove secrets and unnecessary personal, customer, supplier, or production information.
- Confirm scope, period, build or process identity, source evidence, assumptions, and accountable owner.
- Check every row, statement, calculation, status, exception, mitigation, and follow-up action.
- Record the final decision, approvers, rationale, conditions, and evidence in the authorized system of record.
