Scorecards is a feature of the Datadog Service Catalog that helps organizations gauge the performance and reliability of their services by setting industry standards and custom rules. It provides actionable feedback to service owners on an ongoing basis, ensuring adherence to best practices throughout the software development life cycle. Before implementing Scorecards, Datadog relied on a manual production-readiness review process which was not scalable as the organization grew. With Scorecards, teams can define and enforce best practices in collaboration with various stakeholders, improving security, reliability, and performance at scale.
