| Criterion |  Operations ALPEN Method |  Architecture SAAM (Software Architecture Analysis Method) |  Architecture ARID (Active Reviews for Intermediate Designs) |  Operations Failure Mode and Effects Analysis |
|---|---|---|---|---|
Purposedifferent | With an overloaded day full of too many tasks, a realistic picture of the day emerges. The method connects estimating, deciding, and buffer thinking so planning fits available energy and time. | 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. | 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. | For a process, product, or service with noticeable failure risks, the method assesses possible failure modes in advance. It directs attention to combinations of occurrence, effect, and detectability. |
Complexitydifferent | Low | High | Medium | High |
Timedifferent | 10-20 min daily | Preparation, scenario analysis, and findings review; effort depends on scope | 2–4 h review as a planning range; preparation and evaluation additional | 2-6 h |
