|---|---|---|---|---|
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. | A Stock and Flow Diagram shows how stocks, inflows, and outflows shape a system over time. It is especially suited when growth, delays, or capacity limits determine the dynamics. | 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. | ARID examines how well developers can work with a technical design. It focuses on a part of the system that can still be revised, between the architecture overview and the detailed specification. |
Complexitydifferent | Medium | High | High | Medium |
Timedifferent | 3–4 h for initial assessment; preparation and deeper analysis additional | 2-6 h | Preparation, scenario analysis, and findings review; effort depends on scope | 2–4 h review as a planning range; preparation and evaluation additional |
Participantsdifferent | 1 or a small team; particularly suitable for 3–4 people | 1-6 | Architecture experts and stakeholders for scenarios and weighting | Designers, developers as users, and facilitation |
