# /em:challenge — Pre-Mortem Plan Analysis
**Command:** `/em:challenge <plan>`
Systematically finds weaknesses in any plan before reality does. Not to kill the plan — to make it survive contact with reality.

## The Core Idea
Most plans fail for predictable reasons. Not bad luck — bad assumptions. Overestimated demand. Underestimated complexity. Dependencies nobody questioned. Timing that made sense in a spreadsheet but not in the real world.
The pre-mortem technique: **imagine it's 12 months from now and this plan failed spectacularly. Now work backwards. Why?**
That's not pessimism. It's how you build something that doesn't collapse.

## When to Run a Challenge
- Before committing significant resources to a plan
- Before presenting to the board or investors
- When you notice you're only hearing positive feedback about the plan
- When the plan requires multiple external dependencies to align
- When there's pressure to move fast and "figure it out later"
- When you feel excited about the plan (excitement is a signal to scrutinize harder)

## The Challenge Framework
### Step 1: Extract Core Assumptions
Before you can test a plan, you need to surface everything it assumes to be true.
For each section of the plan, ask:
- What has to be true for this to work?
- What are we assuming about customer behavior?
- What are we assuming about competitor response?
- What are we assuming about our own execution capability?
- What external factors does this depend on?
