|---|---|---|---|---|
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. | 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. | When the question is whether two measures are related, the method makes patterns in the data picture visible. It separates felt correlations from relationships that actually show up in the data. | 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 | 3–4 h for initial assessment; preparation and deeper analysis additional | 45-120 min | 30-90 min | Preparation, scenario analysis, and findings review; effort depends on scope |
Participantsdifferent | 1 or a small team; particularly suitable for 3–4 people | 2-6 | 1-4 | Architecture experts and stakeholders for scenarios and weighting |
