|---|---|---|---|---|
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. | Plans often contain assumptions that were never openly stated and remain dangerous precisely because of that. Assumption Surfacing makes these silent premises visible and prioritizes which of them carry the initiative or could sink it. | 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. |
Complexitydifferent | Medium | Low | Medium | High |
Timedifferent | 3–4 h for initial assessment; preparation and deeper analysis additional | 45-90 min | 45-120 min | Preparation, scenario analysis, and findings review; effort depends on scope |
Participantsdifferent | 1 or a small team; particularly suitable for 3–4 people | 2-8 | 2-6 | Architecture experts and stakeholders for scenarios and weighting |
