Scorecards, a feature of the Datadog Software Catalog, enables organizations to gauge the performance and observability of their services, guided by industry standards as well as custom rules, providing actionable feedback to service owners on an ongoing basis. Before implementing Scorecards, Datadog relied on a manual production-readiness review process that was not scalable for growing teams and services. By leveraging Scorecards, Datadog has established and maintained important standards for security, reliability, and performance at scale, eliminating knowledge silos and providing robust guidelines throughout the software development life cycle. The rollout of Scorecards has been progressive, with a focus on promoting a culture shift and communicating the "why" behind each rule and its outcomes. Key metrics have shown that Scorecards are helping to reduce unexpected setbacks, promote best practices early in the development process, and improve the overall efficiency of service launch timelines.
