| Criterion |  Architecture LASR (Lightweight Approach for Software Reviews) |  Architecture C4 Model |  Architecture Architecture Decision Record |  Architecture ATAM (Architecture Tradeoff Analysis Method) |
|---|---|---|---|---|
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. | 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. | An ADR permanently records an architecture decision with context, trade-offs, and consequence. It creates continuity for later changes because the decision path stays traceable. | 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. |
Complexitydifferent | Medium | Low | Low | High |
Timedifferent | 3–4 h for initial assessment; preparation and deeper analysis additional | 1-4 h | 15-45 min | Several meetings plus preparation and analysis; total effort depends on scope |
Participantsdifferent | 1 or a small team; particularly suitable for 3–4 people | 1-5 | 1-3 | Evaluation team, architects, and relevant stakeholders |
Formatdifferent | Workshop + async | Workshop + async | Async | Workshop + async |
Outputdifferent | 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 | Context Diagram, Container Diagram, Component Diagram | ADR File, Decision Log, Rationale | Prioritized quality scenarios in a utility tree, Architecture risks with reasoning and assumptions, Sensitivity and trade-off points, Findings report with open investigations |
