Purposedifferent | When work needs to move between different states or columns, it makes that movement and its handoffs legible. It sorts work by value, risk, and delivery ability. The result is captured as a ROAM Board and an Owner List. | 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 three perspectives matter at the same time, a Three-Circle Venn Diagram shows the overlaps and remainders precisely. It makes visible where shared effect arises and where only a partial perspective applies. | 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 | Low | Medium | Low | High |
Timedifferent | 20-40 min initial, dann laufend | 3–4 h for initial assessment; preparation and deeper analysis additional | 15-45 min | Preparation, scenario analysis, and findings review; effort depends on scope |
Participantsdifferent | 3-15 | 1 or a small team; particularly suitable for 3–4 people | 2-8 | Architecture experts and stakeholders for scenarios and weighting |
