|---|---|---|---|---|
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. | Outcome-Driven Innovation clarifies customer problems, solution opportunities, and evidence. It separates jobs, desired outcomes, importance, satisfaction, and opportunity, and captures results as desired outcome statements, an opportunity landscape, and segments by underserved needs. | LASR helps development teams identify where their software falls short of important quality goals and which improvements to consider. A small group with existing system knowledge can make an initial assessment and investigate open questions in more detail. | 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 | High | Medium | Medium |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | Mehrere Wochen | 3–4 h for initial assessment; preparation and deeper analysis additional | 45-120 min |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 2-6 researchers plus sample | 1 or a small team; particularly suitable for 3–4 people | 2-6 |
Formatsame | Workshop + async | Workshop + async | Workshop + async | Workshop + async |
