|---|---|---|---|---|
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. | 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. | 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 | High | Medium | Medium |
Timedifferent | Several meetings plus preparation and analysis; total effort depends on scope | Preparation, scenario analysis, and findings review; effort depends on scope | 1-3 Tage | 3–4 h for initial assessment; preparation and deeper analysis additional |
Participantsdifferent | Evaluation team, architects, and relevant stakeholders | Architecture experts and stakeholders for scenarios and weighting | 1-4 | 1 or a small team; particularly suitable for 3–4 people |
