|---|---|---|---|---|
Purposedifferent | 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. | An RFC clarifies architecture context, options, and consequences. It structures technical context, alternatives, tradeoffs, open questions, and review feedback, and captures the result as an RFC document, reviewer comments, and a decision rationale. | Helps clarify scope, sequence, and delivery flow in concrete terms. It makes work, boundaries, and order steerable. The result is captured as a RAID Log and a source for status reporting. | 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. |
Complexitydifferent | High | Medium | Low | Medium |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 1-3 Wochen vom Draft bis zur Entscheidung | 30 min Setup, dann laufend | 3–4 h for initial assessment; preparation and deeper analysis additional |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 3-20 Reviewer | 1-3 maintaining, briefing for everyone | 1 or a small team; particularly suitable for 3–4 people |
Formatdifferent | Workshop + async | Async | Async | Workshop + async |
Outputdifferent | Domain functions mapped to components and connections, Quality attributes and evaluation criteria, Typical tasks and their effects on the architecture, Reasoned evaluation or comparison of alternatives | RFC document, Reviewer comments, Decision rationale, Follow-up ADR or tickets | RAID Log, Status Report Source | Lean Mission Statement describing the software’s purpose, Prioritized quality goals and evaluation criteria, Risks and estimated gaps against quality goals, More closely examined findings and open checks |
