| Criterion |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Knowledge Modeling Competency Questions |  Architecture Software Architecture Canvas |
|---|---|---|---|
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. | Competency Questions translate a domain model into concrete questions that it must be able to answer. The method keeps the model's scope clean and prevents pretty but useless structures. | The Software Architecture Canvas reduces a system to the most important architecture decisions, constraints, and interfaces. It is useful when teams need a resilient overall picture quickly. |
