|---|---|---|---|---|
Purposedifferent | An ADR permanently records an architecture decision with context, trade-offs, and consequence. It creates continuity for later changes because the decision path stays traceable. | When demand is still unclear, it measures interest in a feature before it is built. It separates real behavior from polite agreement and deliberately keeps build effort small. | 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 Learning Card connects traceable test results to a reasoned next action while keeping the limits of the insight visible. |
Complexitydifferent | Low | Medium | Medium | Low |
Timedifferent | 15-45 min | 1-5 Tage | 3–4 h for initial assessment; preparation and deeper analysis additional | 25-40 min |
Participantsdifferent | 1-3 | Nutzertraffic | 1 or a small team; particularly suitable for 3–4 people | 1-5 |
Formatdifferent | Async | Async | Workshop + async | Workshop + async |
Outputdifferent | ADR File, Decision Log, Rationale | Click Data, Interest Signal, Learning Decision | 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 | Learning Card with evidence and next action |
