|---|---|---|---|---|
Purposedifferent | In technical failures, the visible symptom often gets mixed up with the actual cause. Fault Isolation narrows the fault space and progressively reduces which part of the system is truly affected. | 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. | When an initiative depends on many people, interests, and power dynamics, Stakeholder Mapping systematically orders the environment. It shows who influences, who is affected, and where relationship management or safeguarding matters first. | 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 | Medium | Low | High |
Timedifferent | 30-180 min | 3–4 h for initial assessment; preparation and deeper analysis additional | 60–90 min | Preparation, scenario analysis, and findings review; effort depends on scope |
Participantsdifferent | 1-6 | 1 or a small team; particularly suitable for 3–4 people | 2-8 | Architecture experts and stakeholders for scenarios and weighting |
