|---|---|---|---|---|
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 an improvement that still has to prove itself in everyday work, the method runs it through small learning loops. It connects planning, checking, and standardization into a repeatable learning mode. | The Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. | 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 h bis mehrere Wochen | 25-40 min | Several meetings plus preparation and analysis; total effort depends on scope |
Participantsdifferent | 1 or a small team; particularly suitable for 3–4 people | 1-8 | 1-5 | Evaluation team, architects, and relevant stakeholders |
