Criterion	Decision Making Eisenhower Matrix	Operations Change Analysis	Operations Failure Mode and Effects Analysis	Architecture SAAM (Software Architecture Analysis Method)
Purposedifferent	It separates true priorities from noise so it becomes clear what should be done now, scheduled, delegated, or dropped.	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.	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.	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.
