valentinozegna/decision-tables

Find every edge case of a feature by enumerating its conditions into an exhaustive decision table, getting a human decision on each uncertain cell, then minimizing the table into a short ordered rule list that is verified cell by cell. Use when defining or changing a feature with interacting conditions (bookings, capacity and waitlists, notifications, permissions, pricing, workflows), when auditing existing behavior for gaps or client/server disagreement, when the user says "decision table", "edge cases", "truth table", "state table" or "what happens when", or before writing the test plan for such a feature.
