Quantifying Architecture Decisions

Translate a business objective into a measurable quality-attribute scenario.

Construct a workload model that captures traffic shape, data volume, latency targets, and growth assumptions.

Represent a distributed system’s responsibilities and trust boundaries with context and container diagrams.

Document architectural assumptions and identify the risks created if each assumption proves false.

Compare candidate architectures with a trade-off matrix covering performance, availability, security, operability, cost, and evolvability.

Write an architecture decision record that states the decision, alternatives, consequences, and conditions for reconsideration.
