cause-effect-graphing

Build a directed graph connecting causes (inputs, preconditions) to effects (outputs, actions) through AND/OR/NOT logic nodes, then mechanically derive a decision table from it — for when conditional logic is too tangled to see clearly in prose or needs to be communicated visually to non-technical stakeholders. Use when the user has complex validation logic with nested conditions (more than ~5 interacting conditions), says the spec seems to have implicit logical structure they can't quite see, or needs to communicate business rules to stakeholders via a diagram. For straightforward conditional logic with 5 or fewer conditions, the decision-tables skill is the faster, more direct path to the same result — reach for this only when the graph itself adds clarity.
