|---|---|---|---|---|
Purposedifferent | 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. | 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. | With a restless workday full of too many open items, the method creates radical simplicity. It directs attention to a short sequence instead of a broad, still-open field. | The method protects energy and attention for the task that creates the largest progress and is often postponed. |
Complexitydifferent | High | Medium | Low | Low |
Timedifferent | Several meetings plus preparation and analysis; total effort depends on scope | 3–4 h for initial assessment; preparation and deeper analysis additional | 5-10 min daily | 15-90 min daily |
Participantsdifferent | Evaluation team, architects, and relevant stakeholders | 1 or a small team; particularly suitable for 3–4 people | 1 | 1 |
Formatdifferent | Workshop + async | Workshop + async | Async | Async |
Outputdifferent | Prioritized quality scenarios in a utility tree, Architecture risks with reasoning and assumptions, Sensitivity and trade-off points, Findings report with open investigations | 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 | Daily Priority List, Completion Notes | Priority Task, Completion Note, Daily Focus |
