|---|---|---|---|---|
Purposedifferent | When a service experience is spread across several touchpoints, it brings frontstage and backstage together. It shows where user contact and internal responsibility must fit. | 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. | 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 complex deviation with several people involved, the method bundles problem, analysis, and decision onto one page. It creates a shared working space where causes, countermeasures, and follow-up fit together. |
Complexitydifferent | High | High | Medium | Medium |
Timedifferent | 0.5-2 Tage | Preparation, scenario analysis, and findings review; effort depends on scope | 3–4 h for initial assessment; preparation and deeper analysis additional | 45-90 min |
