|---|---|---|---|
Purposedifferent | An ADR permanently records an architecture decision with context, trade-offs, and consequence. It creates continuity for later changes because the decision path stays traceable. | For an individual thinking problem with no counterpart immediately available, the method creates a protected space for one's own approaches. It prevents outside opinions from narrowing thinking too early. This lets ideas mature before they go into a group format. | When a team faces an open question with many obvious directions, the method first creates breadth instead of premature commitment. It separates idea flow from evaluation and makes lines of thought visible, creating a pool for selection and further development. |
