## Implementation plan

| Phase | Entry evidence | Actions | Owner | Control | Exit evidence | Due date |
|---|---|---|---|---|---|---|
| 1. Operations — Waterfall Analysis Guide | | During operations, use Waterfall Analysis Guide to connect industry structure, technology, economics, regulation, and execution. Start with dated financial statements, operating metrics, contractual terms, and a reconciled assumption register. Name the accountable owner, the evidence reviewer, the decision deadline, and the output that proves this stage is complete. Record exclusions and unresolved questions rather than allowing them to disappear into narrative. The stage closes only when its evidence can be reproduced by someone who did not prepare it. | | | Required output: a dated industry thesis with sources and monitored assumptions. | |
