## Description

Calculate real cost savings from pattern consolidation with hard numbers. Estimates monthly/annual maintenance costs before and after, projects ROI timeline, shows when investment breaks even.

## Prerequisites

- Consolidation completed (*consolidate command run successfully)
- .state.yaml contains pattern reduction metrics
- Optional: Team salary data for accurate calculations

## Workflow

### Interactive Elicitation

This task uses interactive elicitation to gather cost parameters.

1. **Gather Team Context**
   - Team size (number of developers)
   - Average developer hourly rate (default: $150/hr)
   - Monthly hours spent on UI maintenance (estimate if unknown)
   - Implementation cost estimate

2. **Review Pattern Metrics**
   - Show consolidation metrics (patterns before/after)
   - Confirm reduction percentages
   - Identify highest-impact reductions

3. **Configure Calculation**
   - Ask for conservative vs aggressive estimates
   - Include or exclude training costs
   - Set ROI calculation period (1 year default)

### Steps

1. **Load Consolidation Metrics**
   - Read .state.yaml for pattern reduction data
   - Extract before/after counts for all pattern types
   - Calculate reduction percentages
   - Validation: Consolidation data exists

2. **Calculate Maintenance Cost (Before)**
   - Formula: patterns × hours_per_pattern_monthly × hourly_rate × 12
   - Default: 2 hours/month per pattern for maintenance
   - Include debugging, updates, consistency fixes
   - Validation: Reasonable cost estimate generated

3. **Calculate Maintenance Cost (After)**
   - Same formula with consolidated pattern count
   - Factor in design system overhead (small)
   - Validation: Post-consolidation cost calculated

4. **Calculate Monthly and Annual Savings**
   - Monthly savings = cost_before - cost_after
   - Annual savings = monthly_savings × 12
   - Validation: Positive savings or explain why not

5. **Estimate Implementation Cost**
   - Developer time to create design system
   - Migration effort (from migration strategy)
   - Training time
   - Default: $10,000-15,000 for medium teams
   - Validation: Implementation cost estimated

6. **Calculate ROI Metrics**
   - ROI ratio = annual_savings / implementation_cost
   - Breakeven point = implementation_cost / monthly_savings (in months)
   - 3-year projection = (annual_savings × 3) - implementation_cost
   - Validation: ROI calculations complete

7. **Calculate Velocity Impact**
   - Estimate time saved per feature (fewer component decisions)
   - Project velocity multiplier (3-6x typical)
   - Convert to dollar value (time = money)
   - Validation: Velocity impact quantified

8. **Generate ROI Report**
   - Create roi-analysis.md with executive summary
   - Include detailed calculations with formulas
   - Generate charts (text-based or recommend tools)
   - Show sensitivity analysis (best/worst case)
   - Validation: Comprehensive ROI document created

9. **Create Stakeholder Summary**
   - One-page executive summary
   - Key numbers only (investment, savings, breakeven)
   - Visual comparison (before/after costs)
   - Validation: Stakeholder-ready summary

10. **Update State File**
    - Add ROI section to .state.yaml
    - Record all cost calculations
    - Update phase to "roi_calculated"
    - Validation: State updated with financial data

## Output

- **roi-analysis.md**: Detailed ROI analysis with calculations
- **executive-summary.md**: One-page stakeholder summary
- **cost-breakdown.yaml**: Structured cost data
- **.state.yaml**: Updated with ROI metrics

### Output Format

```yaml

    annual: $374,400
    hours_saved_monthly: 288

  implementation:
    estimated_cost: $12,000
    developer_weeks: 4

  roi_metrics:
    ratio: 31.2
    breakeven_months: 0.38

    year_3_cumulative: $1,111,200

  velocity_impact:
    multiplier: "4-6x"
    time_savings: "70% reduction in UI decisions"
```

## Success Criteria

- [ ] Realistic cost estimates based on team context
- [ ] Both pre and post-consolidation costs calculated
- [ ] ROI ratio shows positive return (>2x minimum)
- [ ] Breakeven point calculated (typically <1 year)
- [ ] Velocity impact quantified
- [ ] Executive summary is stakeholder-ready
- [ ] All calculations show formulas used

## Error Handling

- **No consolidation data**: Exit with message to run *consolidate first
- **Unrealistic costs**: Warn user, suggest reviewing inputs
- **Negative ROI**: Explain why, suggest higher-impact consolidation
- **Missing team data**: Use industry defaults, flag estimates as rough

## Security Considerations

- Salary data is sensitive - only used for calculations, not logged
- Cost reports stored securely
- No external data transmission
- User can review before sharing with stakeholders

## Examples

### Example 1: ROI Calculation

```bash
*calculate-roi
```

  Annual cost: $115,200

💵 SAVINGS:
  Monthly: $43,200
  Annual: $518,400
  3-year total: $1,555,200

**$518,400/year** savings

## ROI
**34.6x return** on investment

## Breakeven

```

## Notes

- Default 2 hours/month per pattern for maintenance (conservative)
- Includes: debugging, updates, consistency fixes, code reviews
- Velocity multiplier (3-6x) based on industry research
- Implementation cost varies by team size and existing tech debt
- ROI improves over time as system matures
- Brad's estimates are conservative (actual savings often higher)
- Use this report to justify design system to stakeholders
- Recalculate ROI after Phase 2 migration to validate projections
