|---|---|---|---|
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. | For technical contradictions or trade-offs, the method looks for solutions that resolve opposing requirements at the same time. It translates limits into an explicit picture of conflict that becomes workable. This produces not just compromises but more elegant principles. | 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 | High | High |
Timedifferent | 3–4 h for initial assessment; preparation and deeper analysis additional | 1-4 h | Several meetings plus preparation and analysis; total effort depends on scope |
Participantsdifferent | 1 or a small team; particularly suitable for 3–4 people | 2-8 | Evaluation team, architects, and relevant stakeholders |
