Purposedifferent | When experiments become unreadable after the fact, it arranges hypothesis, signal, and learning goal on a single canvas. It separates problem, assumption, solution, and evidence. The result is captured as a Completed Experiment Canvas and a Success Metric. | 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. | The Test Card turns a critical assumption into a testable claim and specifies in advance which result counts as success. |
Complexitydifferent | Low | High | Medium | Low |
Timedifferent | 30-60 min | Several meetings plus preparation and analysis; total effort depends on scope | 3–4 h for initial assessment; preparation and deeper analysis additional | 20-35 min |
Participantsdifferent | 1-5 | Evaluation team, architects, and relevant stakeholders | 1 or a small team; particularly suitable for 3–4 people | 1-5 |
