Criterion	Agile WSJF	Operations Failure Mode and Effects Analysis	Architecture SAAM (Software Architecture Analysis Method)	Operations Fishbone Diagram
Purposedifferent	When many tasks compete for the same capacity, it orders work by economic impact. It makes time lost, benefit, and effort comparable together.	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.	When a problem has several possible contributing factors, the method sorts causes by cause areas. It prevents an initial hunch from blocking the view of other plausible drivers.
