Purposedifferent | Value Chain Analysis shows where value is created, costs accrue, and differentiation becomes possible along the process. It compares strengths, risks, market logic, and courses of action. The result is captured as a value-chain map and lever list. | 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 an early product bet still has too many open points, it brings target group, problem, and assumptions into a single view. It condenses the idea so core risks become nameable. | 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 | High | Medium | Medium | High |
Timedifferent | Half day | 3–4 h for initial assessment; preparation and deeper analysis additional | 45-90 min | Preparation, scenario analysis, and findings review; effort depends on scope |
Participantsdifferent | 3-8 | 1 or a small team; particularly suitable for 3–4 people | 1-6 | Architecture experts and stakeholders for scenarios and weighting |
Formatdifferent | Workshop | Workshop + async | Workshop + async | Workshop + async |
Outputdifferent | Value Chain Map, Lever List | 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 | Lean Canvas, Core Assumptions, Experiment Backlog | 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 |
