| Criterion |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Business Strategy Strategic, Tactical and Operational Planning |  Architecture Architecture Decision Record |
|---|---|---|---|
Purposedifferent | ATAM helps teams weigh architecture decisions when quality goals compete. The team considers business goals, stakeholder expectations, and technical decisions together. The evaluation shows which risks need further investigation. | It places decisions and artifacts at the right level. Strategic planning clarifies direction, tactical planning translates it into programs, and operational planning steers concrete processes. | 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. |
