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. | 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. | For a deviation after a change, the method isolates the influence of the altered condition. It narrows down which differences are relevant and which are just accompanying noise. |
Complexitydifferent | High | Low | High | Medium |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 30–60 min per interview | Several meetings plus preparation and analysis; total effort depends on scope | 45-120 min |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 1 participant per interview | Evaluation team, architects, and relevant stakeholders | 2-6 |
