| Criterion |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Agile WSJF |  Architecture C4 Model |  Architecture LASR (Lightweight Approach for Software Reviews) |
|---|---|---|---|---|
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. | When many tasks compete for the same capacity, it orders work by economic impact. It makes time lost, benefit, and effort comparable together. | The C4 Model makes a system legible across several resolution levels, from context down to code. It suits situations where different audiences need to understand the same architecture from different altitudes. | 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 | High | Low | Medium |
Timedifferent | Several meetings plus preparation and analysis; total effort depends on scope | 45-90 min | 1-4 h | 3–4 h for initial assessment; preparation and deeper analysis additional |
Participantsdifferent | Evaluation team, architects, and relevant stakeholders | 3-10 | 1-5 | 1 or a small team; particularly suitable for 3–4 people |
