|---|---|---|---|---|
Purposedifferent | 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. | 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. | In many problem situations, effect is distributed unequally across many causes. A Pareto Analysis separates the few drivers with high leverage from the long remainder and focuses attention on what measurably moves the needle. | The method protects energy and attention for the task that creates the largest progress and is often postponed. |
Complexitydifferent | Medium | High | Low | Low |
Timedifferent | 45-120 min | Preparation, scenario analysis, and findings review; effort depends on scope | 30-60 min | 15-90 min daily |
Participantsdifferent | 2-6 | Architecture experts and stakeholders for scenarios and weighting | 1-6 | 1 |
Formatdifferent | Workshop + async | Workshop + async | Workshop + async | Async |
