### ROI Calculation

```
ROI Score = (Impact × Strategic Value) / Complexity

Impact:     How much does this improve the product?
            1 = Minor polish
            2 = Bug fix / small feature
            3 = Medium feature / significant improvement
            4 = Major feature / game-changer
            5 = Platform-defining capability

Strategic Value: How much does this enable future work?
            1 = Isolated improvement
            2 = Enables one related feature
            3 = Enables multiple features
            4 = Platform foundation
            5 = Transforms product direction

Complexity: Technical difficulty estimate (Low=1, Medium=3, High=5, Very High=8)

Example:
- Fix jitter: (3 × 2) / 1 = 6.0 (excellent)
- Real-time streaming: (4 × 4) / 5 = 3.2 (good)
- Multi-sport platform: (5 × 5) / 8 = 3.1 (good, but long-term)
```

         │  (Do First)          │  (Plan Carefully)
         │                      │
─────────┼──────────────────────┼─────────────
Medium   │  Maintenance         │  Big Bets
ROI      │  (As Needed)         │  (Long-term)
         │                      │
─────────┼──────────────────────┼─────────────
Low ROI  │  Avoid               │  Reconsider
         │  (Low Priority)      │  (Reevaluate)
         │
         └─ Low      Medium    High ─ Complexity
```

### Priority Decision Matrix

**Tier 1 - Quick Wins (High ROI, Low Complexity)**

- Examples: Bug fixes, documentation, small features

**Tier 2 - Strategic Wins (High ROI, Moderate-High Complexity)**

- Plan and execute after low-hanging fruit
- Requires coordination but justified by ROI
- Examples: Infrastructure improvements, major features

**Tier 3 - Big Bets (Medium-High ROI, Very High Complexity)**

- Plan for near-term/long-term roadmap
- Break into phases to reduce initial commitment
- Examples: Platform generalization, new capabilities

**Tier 4 - Technical Debt (Medium ROI, Variable Complexity)**

- Allocate 15-20% of capacity
- Prioritize by impact/complexity ratio
- Examples: Refactoring, test coverage, optimization

**Avoid - Low ROI, High Complexity**

- Reevaluate or deprioritize
- Consider phased approach or alternative solution
- Examples: Over-engineering, premature optimization

## Coordination Patterns

### Sequential Handoff

```
Biomechanics Specialist → Define metric, complexity: Low
Backend Developer → Implement algorithm, complexity: Medium
QA Engineer → Create tests, complexity: Low
Technical Writer → Document API, complexity: Low

Total Complexity: Medium | Total ROI: High (4/5)
```

### Parallel Streams

```
Stream 1: Backend optimization (complexity: High)
Stream 2: Documentation update (complexity: Low)
Stream 3: Test coverage (complexity: Medium)
Dependencies: None | Total Complexity: High
Coordination: Weekly sync on integration points
```

### Critical Path Management

```
Dependencies:
  Design (complexity: Medium) → Implementation (complexity: High) → Testing (complexity: Medium)

Critical path complexity: High (sum of dependencies)
Monitor for delays in high-complexity items
May parallelize testing with late implementation phases
```
