🧠 Strategic Thinking & Decision Making

decision-matrix - Multi-criteria decision analysis with weighted scoring, sensitivity analysis, and uncertainty handling for complex choices between 3-10 options.

bayesian-reasoning-calibration - Probabilistic reasoning with prior/posterior updates, Bayes theorem application, and calibration techniques for reducing overconfidence.

alignment-values-north-star - Strategic alignment framework connecting daily decisions to core values and long-term vision using north star metrics and principle mapping.

environmental-scanning-foresight - Anticipate change through PESTLE analysis, weak signal detection, scenario planning (2x2 matrix), cross-impact analysis, and signposts for early warning systems.

expected-value - Rational decision-making under uncertainty through probability-weighted outcomes (EV = Σ p×v). Covers scenario identification, probability estimation (base rates, triangulation, calibration), payoff quantification (NPV, non-monetary factors), decision trees (fold-back induction, optionality), expected utility for risk aversion, sensitivity analysis, and bias mitigation (overconfidence, sunk costs, tail risk neglect).

heuristics-and-checklists - Practical decision-making through mental shortcuts (heuristics) and systematic error prevention (checklists). Design fast & frugal heuristics (recognition, take-the-best, satisficing), create effective checklists (5-9 killer items, READ-DO vs DO-CONFIRM formats), validate rules empirically (≥80% accuracy target), and mitigate cognitive biases (availability, representativeness, anchoring). Covers aviation, surgical, and software deployment checklists with proven 60-80% error reduction.

hypotheticals-counterfactuals - Explore alternative scenarios and test assumptions through "what if" thinking. Use counterfactual reasoning (backward-looking: "what would have happened if?") to understand causality and learn from decisions. Apply scenario planning (forward-looking: optimistic/baseline/pessimistic futures, 2×2 matrices) to prepare for uncertainty. Conduct rigorous pre-mortems (6-step process: imagine failure, identify causes, vote on risks, assign mitigations). Extract common actions, hedges, and options from scenarios. Define leading indicators with clear thresholds for monitoring which future unfolds. Covers minimal rewrite principle, causal mechanism specification, probability calibration, and stress testing decisions.
