| Criterion |  Innovation Design Sprint |  Engineering Fault Isolation |  Architecture SAAM (Software Architecture Analysis Method) |
|---|---|---|---|
Purposedifferent | When the product question is unclear and time pressure is high, the method takes a team from an open idea to a testable solution. It connects problem understanding, decision, and learning in one compact format, lowering the risk of spending a lot of energy on a mere guess. | In technical failures, the visible symptom often gets mixed up with the actual cause. Fault Isolation narrows the fault space and progressively reduces which part of the system is truly affected. | 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 | High |
Timedifferent | 4-5 Tage | 30-180 min | Preparation, scenario analysis, and findings review; effort depends on scope |
