🧠 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.
