# Ishikawa Diagram: Classic Generation Example

## Input Summary
Last Wednesday we had three payment callback failures affecting 7% of orders. Early clues: the third-party API timed out intermittently, retry logic is inconsistent, monitoring does not cover callback latency, the on-call engineer was unfamiliar with the new flow, and load testing only covered the happy path. Use an Ishikawa diagram to analyze potential root causes and evidence to validate.

## Classic Case Context
Last Wednesday we had three payment callback failures affecting 7% of orders. Early clues: the third-party API timed out intermittently, retry logic is inconsistent, monitoring does not cover callback latency, the on-call engineer was unfamiliar with the new flow, and load testing only covered the happy path. Use an Ishikawa diagram to analyze potential root causes and evidence to validate.

## Skill Used
- Ishikawa Diagram
- Group potential causes so root-cause analysis does not stay vague.
- Best for: Quality issues, incidents, process failures, and operations defects.
- Can generate: Cause categories, testable hypotheses, evidence needs, and fixes.

## Situation Judgment
This is a classic situation for Ishikawa Diagram: the input contains a goal, constraints, stakeholder judgments, and a need for action.

## Executive Summary
Separate facts, assumptions, constraints, and actions first, then use Ishikawa Diagram to turn the material into a deliverable. The output should make an actionable judgment, not merely explain the framework.

## Framework Analysis
| Module | Typical output | Purpose |
| --- | --- | --- |
| Facts | Verifiable information from the input | Avoid intuition-only judgment |
| Assumptions | Unknowns that can change the conclusion | Guide validation |
| Framework analysis | Structure through Ishikawa Diagram | Create shared language |
| Action | Owner, time, metric | Drive execution |

## Reusable Diagram
This is a Markdown-only output. Switch to diagram or PDF-ready output to generate Mermaid.

## Recommendation
Use this as the first decision or workshop artifact, then add real evidence, owners, and dates.

## Risks And Unknowns
- If the input lacks real evidence, ranking and recommendations remain working assumptions.
- The framework cannot replace stakeholder alignment on goals and constraints.
- The diagram is a communication surface, not final truth.

## Next Actions
1. Confirm the goal and non-negotiable constraints.
2. Add the 2-3 pieces of evidence most likely to change the conclusion.
3. Share the output, collect objections, and update the version.
