About This Skill

Decision Matrix Builder generates structured decision analysis tools that surface trade-offs, reduce cognitive bias, and document decision reasoning for future review.

Weighted Scoring Matrix

Collects: options (alternatives being evaluated), criteria (what matters), weights (relative importance 1-10), and scores (how each option performs on each criterion 1-10). Computes weighted scores and ranks options. Sensitivity analysis shows how the ranking changes when weights shift ±20%.

Pre-Mortem Analysis

Ask: "Imagine it's 12 months later and this decision turned out to be a disaster. What went wrong?" Generates a structured list of failure scenarios for each option and asks for probability + impact estimates. Produces expected loss per failure mode.

Second-Order Thinking

For the top-ranked option, generates "And then what?" chains for the top 3 consequences. Surfaces non-obvious second and third-order effects that single-step reasoning misses.

Regret Minimization

Jeff Bezos's framework: "Will I regret not doing this when I'm 80?" Applied as a sanity check after the matrix score to catch cases where analytical rankings conflict with values.

Devil's Advocate

Generates the strongest possible case against the top-ranked option to ensure confirmation bias isn't driving the analysis.

Output

Markdown decision document with matrix tables, sensitivity analysis chart, pre-mortem summary, and recommended option with rationale — ready for team review or personal record.

Use Cases

  • Evaluating technology stack choices (build vs. buy vs. open-source) with weighted criteria
  • Making career decisions with multiple factors (salary, growth, culture, location)
  • Selecting vendors or tools with a structured scoring system that removes gut-feel bias
  • Running pre-mortem analysis on a decision to identify likely failure modes

Pros & Cons

Pros

  • + Sensitivity analysis reveals when the 'winning' option is barely ahead of alternatives
  • + Pre-mortem forces explicit failure scenario thinking before committing
  • + Second-order thinking chains surface consequences that intuition misses
  • + Decision documents serve as institutional memory for why decisions were made

Cons

  • - Scoring matrices can create false precision when criteria weights are themselves uncertain
  • - Time investment (30-60 min) may not be warranted for low-stakes reversible decisions
