| Criterion |  Business Strategy PESTLE Analysis |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Architecture SAAM (Software Architecture Analysis Method) |  Business Strategy Ansoff Matrix |
|---|---|---|---|---|
Purposedifferent | PESTLE Analysis makes political, economic, social, technological, legal, and environmental influences visible. The environment of an initiative is thereby read systematically instead of through isolated trends. | 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. | SAAM helps teams judge an architecture’s suitability for selected tasks and changes. It is particularly useful for examining modifiability and comparing architecture alternatives with clear reasoning. | The Ansoff Matrix organizes growth options by market and product relation. It helps weigh expansion, diversification, and adaptation cleanly against each other. |
