| Criterion |  Operations DMAIC |  Architecture LASR (Lightweight Approach for Software Reviews) |  Operations 8D Problem Solving |
|---|---|---|---|
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. | For an acute quality or delivery problem, the method structures immediate protection and root cause work together. It keeps the situation stable while the actual cause is investigated cleanly. |
Complexitydifferent | High | Medium | High |
Timedifferent | 2-12 Wochen | 3–4 h for initial assessment; preparation and deeper analysis additional | 1-6 Wochen |
Participantsdifferent | 3-10 | 1 or a small team; particularly suitable for 3–4 people | 4-10 |
Formatsame | Workshop + async | Workshop + async | Workshop + 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 | 8D Report, Containment Plan, Root Cause Evidence, Corrective Action Plan |
