| Criterion |  Innovation How Might We |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Architecture C4 Model |
|---|---|---|---|
Purposedifferent | With a stuck problem carrying many implicit assumptions, the method translates observations into open, workable questions. It sharpens the problem frame without pre-thinking the solution, turning frustration or fuzziness into a search space with clear direction. | ATAM helps teams weigh architecture decisions when quality goals compete. The team considers business goals, stakeholder expectations, and technical decisions together. The evaluation shows which risks need further investigation. | The C4 Model makes a system legible across several resolution levels, from context down to code. It suits situations where different audiences need to understand the same architecture from different altitudes. |
Complexitydifferent | Low | High | Low |
Timedifferent | 30–45 min | Several meetings plus preparation and analysis; total effort depends on scope | 1-4 h |
Participantsdifferent | 1-10 | Evaluation team, architects, and relevant stakeholders | 1-5 |
