|---|---|---|---|
Purposedifferent | For an acute quality or delivery problem, the method structures immediate protection and root cause work together. It keeps the situation stable while the actual cause is investigated cleanly. | When content only makes sense internally and users can't find the structure again, card sorting exposes their mental order. Terms, groups, and naming are then aligned with the target group's expectations. | 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. |
Complexitydifferent | High | Low | High |
Timedifferent | 1-6 Wochen | 20-45 min | Preparation, scenario analysis, and findings review; effort depends on scope |
Participantsdifferent | 4-10 | Based on research question | Architecture experts and stakeholders for scenarios and weighting |
