| Criterion |  Architecture Request for Comments |  Agile ROAM Board |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Architecture LASR (Lightweight Approach for Software Reviews) |
|---|---|---|---|---|
Purposedifferent | 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. | 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. | ATAM helps teams weigh architecture decisions when quality goals compete. The team considers business goals, stakeholder expectations, and technical decisions together. The evaluation shows which risks need further investigation. | 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 | Medium | Low | High | Medium |
Timedifferent | 1-3 Wochen vom Draft bis zur Entscheidung | 20-40 min initial, dann laufend | Several meetings plus preparation and analysis; total effort depends on scope | 3–4 h for initial assessment; preparation and deeper analysis additional |
Participantsdifferent | 3-20 Reviewer | 3-15 | Evaluation team, architects, and relevant stakeholders | 1 or a small team; particularly suitable for 3–4 people |
