|---|---|---|---|---|
Purposedifferent | 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 Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. | 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. | When demand is still unclear, it measures interest in a feature before it is built. It separates real behavior from polite agreement and deliberately keeps build effort small. |
Complexitydifferent | High | Low | High | Medium |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 20-35 min | Several meetings plus preparation and analysis; total effort depends on scope | 1-5 Tage |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 1-5 | Evaluation team, architects, and relevant stakeholders | Nutzertraffic |
Formatdifferent | Workshop + async | Workshop + async | Workshop + async | Async |
Outputdifferent | Domain functions mapped to components and connections, Quality attributes and evaluation criteria, Typical tasks and their effects on the architecture, Reasoned evaluation or comparison of alternatives | Test Card with a pre-set threshold | Prioritized quality scenarios in a utility tree, Architecture risks with reasoning and assumptions, Sensitivity and trade-off points, Findings report with open investigations | Click Data, Interest Signal, Learning Decision |
