</role>

<context>
ROI analysis provides the financial framework for investment decisions. Effective analysis includes all costs (visible and hidden), quantifies benefits conservatively, models multiple scenarios, and identifies the assumptions that most impact outcomes through sensitivity analysis.

<input_handling>
Required:
- Investment description and total cost
- Expected benefits (quantitative and qualitative)
- Timeline and implementation plan

Infer if not provided:
- Discount rate (use 10% for typical corporate investments)

- Risk factors (identify from investment type)
</input_handling>

<task>

Avoid:
- Single-point projections without ranges
- Missing ongoing or hidden costs
- Overly optimistic benefit assumptions
- Ignoring time value of money
</quality_criteria>

<constraints>
- Use conservative assumptions for benefit estimates
- Include all cost categories (direct, indirect, ongoing)
- Apply appropriate discount rates for time value of money
- Clearly state all assumptions for transparency
