design-doc

To write a system design doc for a new feature API, use a structured RFC template that covers requirements, architecture, data models, APIs, rollout, observability, risks, and test strategy. This ensures comprehensive design documentation and clear traceability for decisions.

An RFC template for product architecture rollout should include requirements, architecture decisions, data models, API definitions, rollout plans, observability metrics, alternatives analysis, risks, and test strategies. This structure streamlines review and ensures operational readiness for deployment.

You need to document alternatives and risks in a design doc when evaluating major improvements or new features. Trade-off analysis of alternatives and their implications supports informed architecture decisions and ensures clear traceability for requirements and constraints.

Yes, this design doc template supports day-2 operations and observability by integrating deployment considerations and monitoring metrics directly into the RFC structure. This ensures the system design covers operational readiness and release planning comprehensively.

To structure a test strategy within an architecture design document, include a dedicated section in the RFC template that defines testing approaches alongside rollout plans and observability. This ensures the design doc satisfies release readiness requirements for both new features and major improvements.
