How to Use the Decision Matrix

What It Does

The Decision Matrix helps you compare up to 4 options against custom criteria that you weight by importance. Score each option 0-10 per criterion, and the matrix calculates the winner based on what actually matters to you — not gut feel or recency bias.

How to Use It

1. Enter your options in the four slots (e.g., "Buy the desk," "Keep current setup," "Build a standing converter," "Try a standing desk at work").
2. Add 2-5 criteria that matter for this decision. Examples: cost, ergonomics, space required, durability, aesthetics.
3. Assign a weight (1-10) to each criterion. Higher weight = more importance. Be honest — if "aesthetics" doesn't actually matter to you, weight it low.
4. Score each option 0-10 per criterion. Score relative to the best possible outcome, not relative to each other. If one option costs $0 and another costs $500, the $0 option gets a 10 for cost.
5. The matrix automatically calculates weighted scores and highlights the winner.

Real-World Examples

• Job offers: Compare roles by salary, commute time, growth potential, team culture, benefits.
• Tool purchases: Compare software subscriptions by price, features, ease of use, support quality.
• Daily prioritisation: What to work on first — urgency, impact, energy required, deadline proximity.
• Location decisions: Where to live — rent, commute, safety, amenities, space.

Tips for Best Results

• Keep criteria independent. "Cost" and "value for money" measure the same thing. Pick one.
• Limit to 5 criteria. More than that and you're over-analysing. The matrix is a thinking aid, not a substitute for judgment.
• If the result surprises you, challenge your criteria. Sometimes the matrix reveals that "I thought cost mattered most, but I weighted growth higher without realising it." That's useful data.
• Use it fast. Don't agonise over scores. Your first instinct is usually correct — the matrix just makes it visible.

What Problem It Solves

Decision paralysis happens when multiple factors compete for attention and you can't hold them all in your head at once. The matrix externalises the trade-offs. It doesn't make the decision for you, but it makes the trade-offs visible — and visible trade-offs are actionable.
