Begin with the difficulty that blocks useful work: what problem is being addressed, whose concerns matter, which inquiry result is missing, or what advice the available evidence supports giving to a decision-maker.

Use the Table of Contents below to search by a familiar term or working question and find the relevant PatternID. Open the pattern and apply its Problem frame, Solution, worked cases, and checklist to your actual inquiry or decision-support question. Start with the smallest useful result; use another pattern when its contribution is needed, and leave the later choice to the authorized decision-maker.

The Readme offers selected practical entries. The Preface explains how the contributions work together, why this arrangement is useful, and what qualifies a combined result. The full Table of Contents also serves questions outside those examples; the pattern bodies supply the working moves, conditions, and stops. For references to this version, use the Citation.
