| 1 | # A3 Problem Analysis |
| 2 | |
| 3 | Apply A3 problem-solving format for comprehensive, single-page problem documentation and resolution planning. |
| 4 | |
| 5 | ## Description |
| 6 | Structured one-page analysis format covering: Background, Current Condition, Goal, Root Cause Analysis, Countermeasures, Implementation Plan, and Follow-up. Named after A3 paper size; emphasizes concise, complete documentation. |
| 7 | |
| 8 | ## Usage |
| 9 | `/analyse-problem [problem_description]` |
| 10 | |
| 11 | ## Variables |
| 12 | - PROBLEM: Issue to analyze (default: prompt for input) |
| 13 | - OUTPUT_FORMAT: markdown or text (default: markdown) |
| 14 | |
| 15 | ## Steps |
| 16 | 1. **Background**: Why this problem matters (context, business impact) |
| 17 | 2. **Current Condition**: What's happening now (data, metrics, examples) |
| 18 | 3. **Goal/Target**: What success looks like (specific, measurable) |
| 19 | 4. **Root Cause Analysis**: Why problem exists (use 5 Whys or Fishbone) |
| 20 | 5. **Countermeasures**: Proposed solutions addressing root causes |
| 21 | 6. **Implementation Plan**: Who, what, when, how |
| 22 | 7. **Follow-up**: How to verify success and prevent recurrence |
