| Criterion |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Architecture LASR (Lightweight Approach for Software Reviews) |  Decision Making DACI |  Decision Making RAPID |
|---|---|---|---|---|
Purposedifferent | 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. | In cross-functional decisions, responsibilities quickly blur between approval, influence, and execution. DACI arranges these roles so decision pressure, contribution, and information stay cleanly separated. | In complex management decisions, clarity is often missing about who recommends, who agrees, and who makes the decision. RAPID creates this assignment and stabilizes decisions across several levels. |
Complexitydifferent | High | Medium | Low | Medium |
Timedifferent | Several meetings plus preparation and analysis; total effort depends on scope | 3–4 h for initial assessment; preparation and deeper analysis additional | 30-60 min | 45-90 min |
Participantsdifferent | Evaluation team, architects, and relevant stakeholders | 1 or a small team; particularly suitable for 3–4 people | 2-10 | 3-12 |
Formatsame | Workshop + async | Workshop + async | Workshop + async | Workshop + async |
Outputdifferent | Prioritized quality scenarios in a utility tree, Architecture risks with reasoning and assumptions, Sensitivity and trade-off points, Findings report with open investigations | 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 | DACI Matrix, Decision Owner, Decision Log | RAPID Role Map, Recommendation, Decision Log |
