| Criterion |  Product Discovery Working Backwards |  Delivery RAID Log |  Architecture LASR (Lightweight Approach for Software Reviews) |  Agile ROAM Board |
|---|---|---|---|---|
Purposedifferent | When the target state and benefit need to be clear first, it thinks backward from the desired outcome into the product logic. It sharpens vision, objections, and value proposition before elaboration. | Helps clarify scope, sequence, and delivery flow in concrete terms. It makes work, boundaries, and order steerable. The result is captured as a RAID Log and a source for status reporting. | 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. | When work needs to move between different states or columns, it makes that movement and its handoffs legible. It sorts work by value, risk, and delivery ability. The result is captured as a ROAM Board and an Owner List. |
Complexitydifferent | Medium | Low | Medium | Low |
Timedifferent | 4-8 h, mehrere Iterationen | 30 min Setup, dann laufend | 3–4 h for initial assessment; preparation and deeper analysis additional | 20-40 min initial, dann laufend |
Participantsdifferent | 2-6 | 1-3 maintaining, briefing for everyone | 1 or a small team; particularly suitable for 3–4 people | 3-15 |
Formatdifferent | Workshop + async | Async | Workshop + async | Workshop + async |
Outputdifferent | Future Press Release, FAQ, Vision Statement | RAID Log, Status Report Source | 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 | ROAM Board, Owner List |
