## Methodology

### Principles

1. **Conservative estimates** - Use lower bound of published research
2. **Task decomposition** - Break complex work into measurable atomic tasks
3. **Multi-source validation** - Cross-reference 3+ independent studies per category
4. **Reproducible** - Document how estimates can be independently verified

### Example: VNet Creation

| Step                 | Manual     | With Copilot |
| -------------------- | ---------- | ------------ |
| Research docs        | 10 min     | -            |
| Define IP ranges     | 5 min      | 2 min        |
| Write Bicep template | 10 min     | -            |
| Add subnets + NSGs   | 15 min     | 3 min        |
| Test & debug         | 5 min      | 3 min        |
| **Total**            | **45 min** | **10 min**   |

**Result**: 78% time savings (aligns with Forrester 88%, adjusted conservatively)

## Assumptions & Limitations

### Assumptions

- **Skill level**: Intermediate professionals (3-5 years experience)
- **Tool familiarity**: 1+ weeks with AI coding tools
- **Environment**: Standard enterprise Azure setup
- **Review included**: Estimates include code review time

### Not Included

- Initial AI tool learning curve (2-4 weeks)
- Organizational change management
- Meeting/approval coordination time
- Azure API wait times

---

## Using These Estimates

### For Demos

1. Focus on **time saved per task**, not monetary values
2. Reference this document for credibility
3. Use conservative figures (better to exceed expectations)

### For ROI Discussions

1. Let customers apply their own labor rates
2. Aggregate across team size × task frequency
3. Include qualitative benefits (quality, satisfaction)

### For Pilots

1. Baseline current manual time
2. Track same tasks with AI assistance
3. Calculate and refine estimates
