| Criterion |  Product Strategy Impact Mapping |  Architecture SAAM (Software Architecture Analysis Method) |  Delivery Communication Plan |
|---|---|---|---|
Purposedifferent | When a goal needs to be connected to several possible paths, it shows chains of impact instead of feature lists. It connects business goal, behavior change, and measures. | 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. | When many people need to be informed in parallel and messages would otherwise arrive unevenly or too late, a Communication Plan orders communication reliably. Channels, audiences, and cadences interlock so important information doesn't get lost. |
Complexitydifferent | Medium | High | Low |
Timedifferent | 45-90 min | Preparation, scenario analysis, and findings review; effort depends on scope | 45-90 min |
Participantsdifferent | 3-8 | Architecture experts and stakeholders for scenarios and weighting | 2-6 |
Formatdifferent | Workshop | Workshop + async | Workshop + async |
Outputdifferent | Impact Map, Outcome Hypotheses, Delivery Options | 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 | Communication Plan, Channel Matrix, Message Cadence |
