|---|---|---|---|---|
Purposedifferent | PESTLE Analysis makes political, economic, social, technological, legal, and environmental influences visible. The environment of an initiative is thereby read systematically instead of through isolated trends. | 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 several people work toward one goal but hold different mental maps, Alignment Mapping makes the discrepancies visible. It arranges goals, assumptions, and priorities so shared direction becomes verifiable. | SAAM helps teams judge an architecture’s suitability for selected tasks and changes. It is particularly useful for examining modifiability and comparing architecture alternatives with clear reasoning. |
Complexitydifferent | Medium | Medium | Medium | High |
Timedifferent | 1-3 h | 3–4 h for initial assessment; preparation and deeper analysis additional | 1-2 h | Preparation, scenario analysis, and findings review; effort depends on scope |
Participantsdifferent | 2-10 | 1 or a small team; particularly suitable for 3–4 people | 4-12 | Architecture experts and stakeholders for scenarios and weighting |
Formatdifferent | Workshop + async | Workshop + async | Workshop | Workshop + async |
Outputdifferent | PESTLE Map, External Risks, Strategic Questions | 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 | Alignment Map, Open Issues, Decision Questions | Domain functions mapped to components and connections, Quality attributes and evaluation criteria, Typical tasks and their effects on the architecture, Reasoned evaluation or comparison of alternatives |
