| Criterion |  Architecture Risk Storming |  Operations Change Analysis |  Product Discovery Assumption Mapping |  Architecture SAAM (Software Architecture Analysis Method) |
|---|---|---|---|---|
Purposedifferent | Helps clarify architecture context, options, and consequences in concrete terms. It organizes technical context, alternatives, and consequences. The result is captured as an Annotated Diagram, a Prioritized Risk List, and an Action Backlog. | For a deviation after a change, the method isolates the influence of the altered condition. It narrows down which differences are relevant and which are just accompanying noise. | When assumptions still sit unordered in the room, it weighs uncertainty against leverage. It makes visible which hypotheses should be checked first. | 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 | Low | Medium | Medium | High |
Timedifferent | 60-90 min | 45-120 min | 45-60 min | Preparation, scenario analysis, and findings review; effort depends on scope |
Participantsdifferent | 4-12 | 2-6 | 2-8 | Architecture experts and stakeholders for scenarios and weighting |
Formatdifferent | Workshop | Workshop + async | Workshop + async | Workshop + async |
Outputdifferent | Annotated Diagram, Prioritized Risk List, Action Backlog | Change Matrix, Cause Hypotheses, Validation Questions, Action List | Assumption map, Test backlog, Risk ranking | 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 |
