| Criterion |  Architecture SAAM (Software Architecture Analysis Method) |  Operations Eat the Frog |  Operations Ivy Lee Method |  Operations Change 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 method protects energy and attention for the task that creates the largest progress and is often postponed. | With a restless workday full of too many open items, the method creates radical simplicity. It directs attention to a short sequence instead of a broad, still-open field. | 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. |
Complexitydifferent | High | Low | Low | Medium |
Timedifferent | Preparation, scenario analysis, and findings review; effort depends on scope | 15-90 min daily | 5-10 min daily | 45-120 min |
Participantsdifferent | Architecture experts and stakeholders for scenarios and weighting | 1 | 1 | 2-6 |
Formatdifferent | Workshop + async | Async | Async | 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 | Priority Task, Completion Note, Daily Focus | Daily Priority List, Completion Notes | Change Matrix, Cause Hypotheses, Validation Questions, Action List |
