|---|---|---|---|---|
Purposedifferent | 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. | 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. | In change initiatives, supporting and restraining forces sit at the table at the same time. Force Field Analysis makes these tensions explicit and shows where change can be pushed forward by strengthening or relieving. | 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 | 45-120 min | 3–4 h for initial assessment; preparation and deeper analysis additional | 45-90 min | Preparation, scenario analysis, and findings review; effort depends on scope |
Participantsdifferent | 2-6 | 1 or a small team; particularly suitable for 3–4 people | 3-12 | Architecture experts and stakeholders for scenarios and weighting |
