| Criterion |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Architecture Architecture Communication Canvas |  Architecture Views and Beyond |  Architecture LASR (Lightweight Approach for Software Reviews) |
|---|---|---|---|---|
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. | The Architecture Communication Canvas plans architecture communication so the right people receive the right message. The method turns technical complexity into deliberate communication design. | Views and Beyond organizes architecture into several views so no single diagram has to do everything at once. This makes it possible to choose the representation that fits the stakeholder's question. | LASR helps development teams identify where their software falls short of important quality goals and which improvements to consider. A small group with existing system knowledge can make an initial assessment and investigate open questions in more detail. |
Complexitydifferent | High | Medium | Medium | Medium |
Timedifferent | Several meetings plus preparation and analysis; total effort depends on scope | 60-120 min | 1-3 Tage | 3–4 h for initial assessment; preparation and deeper analysis additional |
