+=== DORA and Metrics ===

+DORA stands for DevOps Research and Assessment https://dora.dev/. It's a framework developed by a team at Google specifically to measure the performance of DevOps teams.
+DORA isn't a set of practices, but rather a way to assess how well your DevOps practices are working  by focusing on four key metrics:
+  * Deployment Frequency: How often does your team deploy code to production?
+  * Mean Lead Time for Changes: How long does it typically take to get a code change from commit to production?
+  * Change Failure Rate: How often do deployments fail?
+  * Time to Restore Service: How long does it take to recover from a deployment failure?
+By tracking these metrics,  teams can identify areas for improvement and  work towards becoming high-performing DevOps teams. These high performing teams are typically able to deploy code more frequently, with fewer failures, and recover from failures more quickly.
