| Criterion |  Architecture SAAM (Software Architecture Analysis Method) |  Business Strategy TOWS Matrix |  Business Strategy GAP Analysis |
|---|---|---|---|
Purposedifferent | 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. | The TOWS Matrix connects internal strengths and weaknesses with external opportunities and threats into action-oriented strategies. It goes a step further than a pure stocktaking. | GAP Analysis compares the current state with a target picture and makes the distance manageable. It becomes useful when, ahead of new initiatives, it must become clear which capabilities, processes, or resources are missing. |
Complexitydifferent | High | Medium | Medium |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 1-2 h | 1-3 h |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 3-10 | 2-8 |
Formatdifferent | Workshop + async | Workshop | Workshop + async |
Outputdifferent | 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 | TOWS Matrix, Strategic Options, Priority Actions | Gap Matrix, Action Plan, Risk Notes |
