|---|---|---|---|
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. | 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 recurring operational tasks or incidents, the method keeps solid action logic ready. It reduces uncertainty when time pressure, role changes, or rare situations demand fast access. |
Complexitydifferent | Low | Medium | Low |
Timedifferent | 15-45 min | 3–4 h for initial assessment; preparation and deeper analysis additional | 20-60 min |
Participantsdifferent | 1-3 | 1 or a small team; particularly suitable for 3–4 people | 1-4 |
Formatdifferent | Async | Workshop + async | Async |
Outputdifferent | ADR File, Decision Log, Rationale | 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 | Runbook, Checklist, Escalation Path |
