Selected:Risk Storming Eisenhower Matrix Architecture Decision Record ATAM (Architecture Tradeoff Analysis Method)

Criterion	Architecture Risk Storming	Decision Making Eisenhower Matrix	Architecture Architecture Decision Record	Architecture ATAM (Architecture Tradeoff Analysis Method)
Purposedifferent	Helps clarify architecture context, options, and consequences in concrete terms. It organizes technical context, alternatives, and consequences. The result is captured as an Annotated Diagram, a Prioritized Risk List, and an Action Backlog.	It separates true priorities from noise so it becomes clear what should be done now, scheduled, delegated, or dropped.	An ADR permanently records an architecture decision with context, trade-offs, and consequence. It creates continuity for later changes because the decision path stays traceable.	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.
