sysdesign-tradeoff-framing

To document system design tradeoffs, articulate explicit architectural options and record them using an Architecture Decision Record (ADR) format that captures per-option costs and benefits to prevent hand-waving decisions.

An ADR format aligned with NFR priorities includes a decision sentence, per-option gives and costs, a binding constraint, cited non-functional requirements, and a revisit trigger to ensure replayable architectural reasoning.

Write an architecture decision record by framing two viable options across domains like scalability, availability, latency, and cost, then document the binding constraint and explicit reasoning to create a replayable decision.

You need to cite NFR priorities in a system design tradeoff decision whenever you are choosing between at least two viable options, ensuring the binding constraint reflects your non-functional requirement priorities.

Yes, this approach to architectural tradeoffs produces an ADR that preserves rejected options for future context and establishes a revisit trigger to re-evaluate the decision when conditions change.

To make a replayable system design choice, an architecture decision record should include a decision sentence, per-option gives and costs, a binding constraint, cited NFR priorities, and a revisit trigger.
