# /sench-market - Market Definition & Scoping

Comprehensive market opportunity mapping for venture design. Think wide before thinking right.

## Usage

```
/sench-market {market/industry}           # Default (English)
/sench-market {market/industry} --fr      # French output
/sench-market {market/industry} --en      # English output (explicit)
```

## Philosophy

**Scope broadly, filter later.**

- Prioritize coverage over early precision
- Reserve judgment on viability until scoping is complete
- Use value chains as exploration scaffolds
- Document assumptions explicitly
- Resist premature focus

## Workflow

```
Input (market/industry) + optional --fr/--en
    ↓
1. Market Perimeter Definition
    ↓
2. Value Chain Mapping
    ↓
3. Opportunity Exploration
    ↓
4. Adjacent Market Discovery
    ↓
5. Report → {market}_opportunity_map.md
```

## Rules

1. **Exhaustiveness first** - capture everything, filter later
2. **No premature filtering** - avoid attractiveness judgments
3. **Single output file** - `{market}_opportunity_map.md`
4. **Sources required** - include URLs for all market data
5. **Make assumptions explicit** - state what you assumed

---

## Phase 1: Market Perimeter Definition

### Guiding Questions

- What could reasonably belong to the market we are exploring?
- What problems, jobs, or use cases might exist even if they are not obvious today?
- What adjacent or emerging spaces could be relevant?
- Is there anything happening in other countries that doesn't exist locally but could be interesting?
- What parts of the value chain are often overlooked?
- What would we regret not having explored later?

## Phase 2: Value Chain Mapping

### Value Chain Framework

```
Raw Materials → Components → Assembly → Distribution → Retail → End User → After-Sales
     ↓              ↓           ↓           ↓          ↓         ↓           ↓
  [Players]    [Players]   [Players]   [Players]  [Players] [Players]   [Players]
```

### For Each Stage, Identify:

1. **Key players** - incumbents, challengers, startups
2. **Margin structure** - who captures value
3. **Pain points** - inefficiencies, friction
4. **Innovation opportunities** - what could be improved
5. **Digital penetration** - how digitized is this stage
