|---|---|---|---|---|
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. | When story, test, and implementation could drift apart, it brings business perspective, engineering, and quality together early. It prevents a story from being read differently only late in the process. | arc42 structures architecture knowledge so teams can document system, decisions, and risks consistently. The template builds a living understanding of the architecture instead of scattered notes. | 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 | 15-30 min | 1-2 Tage | Several meetings plus preparation and analysis; total effort depends on scope |
Participantsdifferent | 1 or a small team; particularly suitable for 3–4 people | 3 | 1-4 | Evaluation team, architects, and relevant stakeholders |
