Criterion	Decision Making Eisenhower Matrix	Operations Change Analysis	Operations Root Cause Tree 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 problem with several suspected causes, the method builds a causal structure instead of a mere list. It makes visible how causes connect and where the strongest points of leverage lie.	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.
