|---|---|---|---|
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. | When there is uncertainty about the real course of a process, the method brings observation to the place where work happens. It combines perception, follow-up questions, and process knowledge so decisions rest on actual workflows instead of assumptions. | 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. |
Complexitydifferent | High | Low | High |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 30-120 min | Several meetings plus preparation and analysis; total effort depends on scope |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 2-6 | Evaluation team, architects, and relevant stakeholders |
Formatdifferent | Workshop + async | Workshop | Workshop + 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 | Observation Notes, Improvement Ideas | Prioritized quality scenarios in a utility tree, Architecture risks with reasoning and assumptions, Sensitivity and trade-off points, Findings report with open investigations |
