| Criterion |  Systems Thinking Leverage Points |  Systems Thinking Future Reality Tree |  Architecture LASR (Lightweight Approach for Software Reviews) |
|---|---|---|---|
Purposedifferent | Leverage Points show exactly where interventions in a system produce a disproportionate effect. It draws relationships, patterns, and feedback loops. The result is captured as a leverage map and action strategy. | A Future Reality Tree shows how desired actions are meant to lead to a better system state. The method checks whether a path of change holds together logically before time flows into implementation. | 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. |
Complexitydifferent | High | High | Medium |
Timedifferent | Half day | 2-4 h | 3–4 h for initial assessment; preparation and deeper analysis additional |
Participantsdifferent | 3-12 | 3-8 | 1 or a small team; particularly suitable for 3–4 people |
Formatdifferent | Workshop | Workshop | Workshop + async |
Outputdifferent | Leverage Map, Action Strategy | Future Reality Tree, Negative Branches, Assumption List, Improved Injections | 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 |
