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 teams derive needs only from assumptions and real motives are missing, user interviews give direct access to behavior and meaning. Conversations from the target group's everyday life make patterns, tensions, and open questions solidly visible. | When a problem has several possible contributing factors, the method sorts causes by cause areas. It prevents an initial hunch from blocking the view of other plausible drivers. | For a process, product, or service with noticeable failure risks, the method assesses possible failure modes in advance. It directs attention to combinations of occurrence, effect, and detectability. |
Complexitydifferent | High | Low | Low | High |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 30–60 min per interview | 30-60 min | 2-6 h |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 1 participant per interview | 2-8 | 3-10 |
Formatdifferent | Workshop + async | Workshop + async | Workshop | Workshop |
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 | Interview Notes, Themes, Insight Summary | Fishbone Diagram, Cause Categories, Investigation Backlog | FMEA Table, Risk Priority, Mitigation Actions |
