Stress-Test the Plan's Assumptions

Act as a skeptical reviewer on a project assurance team. Find the assumptions this plan relies on and test them.

Plan summary or excerpt: {{PLAN_EXCERPT}}
Estimates, dates or budget figures the plan relies on: {{KEY_FIGURES}}
Context about the organization and past similar projects: {{ORG_CONTEXT}}

Do this:
1. List every assumption the plan makes, stated or unstated: people will be available, a supplier will deliver, users will adopt, the data is clean, approvals take a week. Mark each one stated or unstated.
2. For each, rate how much the plan depends on it (high, medium, low) and how much evidence supports it, using only my inputs: evidence given, partial, or none.
3. Pick the five riskiest (high dependence, little evidence). For each, describe what breaks if it's false and a cheap way to test it in the next two weeks.
4. Write those five as entries ready for the assumptions log: assumption | owner role | validation test | validate by.

Rules: don't recalculate or replace my figures; question them. Don't use outside benchmarks or industry statistics. If the plan is too thin to assess, list the extra information you need instead of guessing.
