| Criterion |  Architecture ARID (Active Reviews for Intermediate Designs) |  Architecture LASR (Lightweight Approach for Software Reviews) |  Agile 4Ls Retrospective |
|---|---|---|---|
Purposedifferent | ARID examines how well developers can work with a technical design. It focuses on a part of the system that can still be revised, between the architecture overview and the detailed specification. | 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. | When a sprint should not only be assessed but also learned from, it captures experience in clear learning categories. It records what worked, what's missing, and what should run differently next time. |
Complexitydifferent | Medium | Medium | Low |
Timedifferent | 2–4 h review as a planning range; preparation and evaluation additional | 3–4 h for initial assessment; preparation and deeper analysis additional | 45–75 min |
Participantsdifferent | Designers, developers as users, and facilitation | 1 or a small team; particularly suitable for 3–4 people | Team members involved |
Formatdifferent | Workshop + async | Workshop + async | Workshop |
Outputdifferent | Prioritized development tasks, Jointly produced code or pseudocode, Observed difficulties and open design questions, Proposed design revisions | 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 | 4Ls Board, Learning Themes, Improvement Actions |
