Criterion	Decision Making Eisenhower Matrix	Architecture ATAM (Architecture Tradeoff Analysis Method)	Product Discovery Assumption Mapping	Decision Making Pareto Analysis
Purposedifferent	It separates true priorities from noise so it becomes clear what should be done now, scheduled, delegated, or dropped.	ATAM helps teams weigh architecture decisions when quality goals compete. The team considers business goals, stakeholder expectations, and technical decisions together. The evaluation shows which risks need further investigation.	When assumptions still sit unordered in the room, it weighs uncertainty against leverage. It makes visible which hypotheses should be checked first.	In many problem situations, effect is distributed unequally across many causes. A Pareto Analysis separates the few drivers with high leverage from the long remainder and focuses attention on what measurably moves the needle.
