# Concept Fan

Expand thinking from purpose through concepts to directions to ideas using de Bono's Concept Fan technique. Move between levels of abstraction to find new approaches.

## HARD-GATE

Cannot exit strategy until ≥80% of each budget line is consumed OR yield targets are met with justification for remaining budget.

## Available Tactics

| Tactic | Role |
|--------|------|
| concept-hierarchy | Build concept levels from purpose through concepts to ideas |

## Available SOPs

| SOP | Role |
|-----|------|
| concept-fan-expansion | Expand fan from purpose → concepts → directions → ideas |
| escape-technique | Escape dominant concept to find alternative concepts |
| fractionation | Split broad concepts into finer units |
| alternatives-generation | Generate alternative ideas at each level |
| lateral-synthesis | Synthesize concept fan outputs |

## Execution Guidance

1. **Define purpose**: Clarify the ultimate purpose (rightmost point of fan)
2. **Identify concepts**: Find broad approaches that serve the purpose
3. **Generate directions**: For each concept, identify specific directions
4. **Produce ideas**: For each direction, generate concrete ideas
5. **Escape and expand**: Use escape-technique if stuck at any level
6. **Synthesize**: Produce structured output via lateral-synthesis

## Available Tactics

Optional, no fixed order; the final leaf is always a sop.

| Tactic | When to use |
| --- | --- |
| concept-hierarchy | Build concept levels from purpose through concepts to ideas, with escape and fractionation at each level. |

## Available SOPs

Optional, no fixed order; the final leaf is always a sop.

| SOP | When to use |
| --- | --- |
| alternatives-generation | Generate alternatives for every known approach — ensure no approach goes unchallenged. |
| concept-fan-expansion | Expand concept fan from purpose through concepts to directions to ideas (de Bono Concept Fan). |
| escape-technique | Identify dominant thinking pattern and escape it via deliberate pattern-breaking. |
| fractionation | Split concepts into smaller units and recombine them differently to produce novel structures. |
| lateral-synthesis | Synthesize all lateral thinking intermediate outputs into a structured idea report. |
