|---|---|---|---|
Purposedifferent | 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. | 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 an idea hinges on one critical unknown, it prioritizes testing that exact piece of uncertainty first. It separates problem, assumption, solution, and evidence. The result is captured as a prioritized list of assumptions, a test plan, and a result report. |
Complexitydifferent | Medium | High | Medium |
Timedifferent | 3–4 h for initial assessment; preparation and deeper analysis additional | Preparation, scenario analysis, and findings review; effort depends on scope | 1-2 Wochen pro Iteration |
Participantsdifferent | 1 or a small team; particularly suitable for 3–4 people | Architecture experts and stakeholders for scenarios and weighting | 2-6 |
