| Criterion |  Delivery Cost of Delay |  Operations Eat the Frog |  Architecture ATAM (Architecture Tradeoff Analysis Method) |  Operations Ivy Lee Method |
|---|---|---|---|---|
Purposedifferent | Helps clarify scope, order, and delivery flow in concrete terms. It makes work, constraints, and sequence manageable. The result is captured as a Cost of Delay table and prioritization sequence. | 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. | 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. |
