| Criterion |  Delivery Cost of Delay |  Architecture ARID (Active Reviews for Intermediate Designs) |  Operations Eat the Frog |  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. | ARID examines how well developers can work with a technical design. It focuses on a part of the system that can still be revised, between the architecture overview and the detailed specification. | 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. |
Complexitydifferent | High | Medium | Low | Low |
Timedifferent | 90-180 min | 2–4 h review as a planning range; preparation and evaluation additional | 15-90 min daily | 5-10 min daily |
