As a Cloud Native Platform Associate, you are tasked with improving software delivery efficiency using...

Lead Time for Changes is the DORA metric that best measures the efficiency and impact of platform initiatives. Option A is correct because it tracks the time from code commit to successful production deployment, directly reflecting how effectively a platform enables developers to deliver software.

Option B (MTTR) measures resilience and recovery speed, not efficiency. Option C (Change Failure Rate) measures deployment stability, while Option D (SLAs) are contractual agreements, not engineering performance metrics.

By reducing lead time, platform engineering demonstrates its ability to provide self-service, automation, and streamlined CI/CD workflows. This makes Lead Time for Changes a critical measurement of platform efficiency and developer experience improvements.
