CAPM Practice: Validate requirements through product delivery

Canary releases deploy to a small user percentage first. If real-user behavior validates the requirements (positive metrics, low errors), the release gradually expands. This staged validation catches requirements issues that testing didn't reveal, while limiting impact to a small user population.

**Why not A:** A colored release label system for categorizing requirements by urgency describes a triage or prioritization scheme, not canary releasing. Canary releasing is a deployment strategy that gradually exposes new features to increasing percentages of production users to validate requirements with real usage data.

**Why not B:** Canary releasing is not a security scanning technique. It is a deployment and validation strategy where new features are released to a small subset of users first, with the rollout expanding only if monitoring confirms positive outcomes. Security scanning is a separate activity.

**Why not D:** The canary metaphor comes from coal mining (canary in a coal mine detecting danger), not from literal canary birds in production environments. In software, canary releasing means using a small user group as an early warning system to detect problems before full deployment.
