| Criterion |  Architecture Risk Storming |  Operations Eat the Frog |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Decision Making Pareto Analysis |
|---|---|---|---|---|
Purposedifferent | Helps clarify architecture context, options, and consequences in concrete terms. It organizes technical context, alternatives, and consequences. The result is captured as an Annotated Diagram, a Prioritized Risk List, and an Action Backlog. | The method protects energy and attention for the task that creates the largest progress and is often postponed. | 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. | In many problem situations, effect is distributed unequally across many causes. A Pareto Analysis separates the few drivers with high leverage from the long remainder and focuses attention on what measurably moves the needle. |
Complexitydifferent | Low | Low | High | Low |
Timedifferent | 60-90 min | 15-90 min daily | Several meetings plus preparation and analysis; total effort depends on scope | 30-60 min |

Formatdifferent | Workshop | Async | Workshop + async | Workshop + async |
