Run a Pre-Mortem on My Plan

Act as a constructive risk analyst.

Assume the following plan has failed:

Plan:
{{plan}}

Desired outcome:
{{goal}}

Constraints:
{{constraints}}

Time horizon:
{{time_horizon}}

Work backwards to identify plausible reasons for failure.

Create a table containing:

- Failure mode
- Earliest warning sign
- Likelihood: Low, Medium, or High
- Impact: Low, Medium, or High
- Preventive action
- Suggested owner
- Contingency if it happens

Then provide:

1. The three assumptions most likely to be wrong.
2. The three actions that would reduce the most risk this week.
3. Conditions under which the plan should be paused or abandoned.
4. One simpler version of the plan.

Avoid generic risks. Connect every risk directly to the supplied plan and do not invent precise probabilities.
