|---|---|---|---|---|
Purposedifferent | When there is uncertainty about the real course of a process, the method brings observation to the place where work happens. It combines perception, follow-up questions, and process knowledge so decisions rest on actual workflows instead of assumptions. | 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. | For a process, product, or service with noticeable failure risks, the method assesses possible failure modes in advance. It directs attention to combinations of occurrence, effect, and detectability. |
Complexitydifferent | Low | Medium | Low | High |
Timedifferent | 30-120 min | 3–4 h for initial assessment; preparation and deeper analysis additional | 20-35 min | 2-6 h |
Participantsdifferent | 2-6 | 1 or a small team; particularly suitable for 3–4 people | 1-5 | 3-10 |
