⚖️ Decision Matrix (MCDA / EEV)
Philosophy: Complex decisions fail because people optimize for one variable while ignoring five others.
1. When to Use
- Choosing between 2+ options with multiple trade-offs
- Any decision where "it depends" is the current answer
- When stakeholders disagree on priorities
2. Execution Workflow
STEP 1: LIST OPTIONS
└─ Must have ≥2 distinct options (no straw men)
STEP 2: DEFINE CRITERIA
└─ List 3-7 evaluation criteria
└─ Each criterion must be measurable or scorable (1-10)
STEP 3: WEIGHT CRITERIA
└─ Assign percentage weights (must sum to 100%)
└─ Force-rank: "If you could only optimize for ONE criterion, which?"
STEP 4: SCORE EACH OPTION
└─ Score 1-10 per criterion per option
└─ Justify each score in one sentence
STEP 5: COMPUTE EEV
└─ EEV = Σ (Score × Weight) for each option
└─ Rank options by total EEV
STEP 6: SANITY CHECK
└─ Does the winner "feel" right?
└─ If not, a hidden criterion exists — surface it and re-run
3. Output Format
# Decision: [Question]
## Criteria & Weights
| # | Criterion | Weight |
|---|-----------|--------|
| 1 | [Name] | [X]% |
| 2 | [Name] | [X]% |
## Scoring Matrix
| Option | C1 | C2 | C3 | **EEV** |
|--------|----|----|-----|---------|
| A | 8 | 6 | 7 | **7.1** |
| B | 5 | 9 | 4 | **6.2** |
## Recommendation
[Winner] with EEV of [X]. Key differentiator: [criterion].
## Sensitivity Analysis
If [criterion weight] changed by ±10%, would the winner change? [Yes/No]
4. Rules
- Never let one criterion dominate (max weight 40%)
- If an option scores 0 on a criterion, flag it as a potential dealbreaker
- Always run sensitivity analysis on the top weight
