| Criterion |  Product Discovery Opportunity Interview |  Architecture LASR (Lightweight Approach for Software Reviews) |  Architecture Architecture Decision Record |  Operations Failure Mode and Effects Analysis |
|---|---|---|---|---|
Purposedifferent | When opportunities are still hidden behind signals of need, it structures conversations around needs and obstacles. It looks for patterns that lead to new product opportunities. | 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. | 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. | 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 | Medium | Medium | Low | High |
Timedifferent | 30-60 min je Interview | 3–4 h for initial assessment; preparation and deeper analysis additional | 15-45 min | 2-6 h |
Participantsdifferent | 5-12 Interviews | 1 or a small team; particularly suitable for 3–4 people | 1-3 | 3-10 |
Formatdifferent | Workshop + async | Workshop + async | Async | Workshop |
Outputdifferent | Interview Notes, Opportunity Themes, Customer Quotes | 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 | ADR File, Decision Log, Rationale | FMEA Table, Risk Priority, Mitigation Actions |
