|---|---|---|---|
Purposedifferent | For a process problem with fluctuating performance, the method brings analysis and improvement into a disciplined sequence. It creates a framework in which numbers, causes, and control come together. | 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 RFC clarifies architecture context, options, and consequences. It structures technical context, alternatives, tradeoffs, open questions, and review feedback, and captures the result as an RFC document, reviewer comments, and a decision rationale. |
Complexitydifferent | High | Medium | Medium |
Timedifferent | 2-12 Wochen | 3–4 h for initial assessment; preparation and deeper analysis additional | 1-3 Wochen vom Draft bis zur Entscheidung |
Participantsdifferent | 3-10 | 1 or a small team; particularly suitable for 3–4 people | 3-20 Reviewer |
Formatdifferent | Workshop + async | Workshop + async | Async |
Outputdifferent | Project Charter, Measurement Plan, Cause Analysis, Control Plan | 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 | RFC document, Reviewer comments, Decision rationale, Follow-up ADR or tickets |
