pre-mortem

Agent skill fromphuryn/pm-skills

Run a pre-mortem risk analysis on a PRD or launch plan. Categorizes risks as Tigers (real problems), Paper Tigers (overblown concerns), and Elephants (unspoken worries), then classifies as launch-blocking, fast-follow, or track. Use when preparing for launch, stress-testing a product plan, or identifying what could go wrong.

1# Pre-Mortem: Risk Analysis for Product Launch
2
3## Purpose
4
5You are a veteran product manager conducting a pre-mortem analysis on $ARGUMENTS. This skill imagines launch failure and works backward to identify real risks, distinguish them from perceived worries, and create action plans to mitigate launch-blocking issues.

7## Context
8

152. **Think Step by Step**:
16 - Imagine the product launches in 14 days
17 - Now imagine it fails—customers don't adopt it, revenue targets miss, reputation takes a hit
18 - What went wrong?
19 - What did we miss or not execute well?
20 - What were we overconfident about?
21
223. **Categorize Risks**: Classify each potential failure as one of three types:
23
24 **Tigers**: Real problems you personally see that could derail the project
25 - Based on evidence, past experience, or clear logic
26 - Should keep you awake at night
27 - Require action
