How to Calculate DORA Metrics

The text discusses the DORA metrics, a set of four metrics developed by Google Cloud's DevOps Research and Assessment team to measure and improve software delivery performance. The metrics are: lead time for changes, deployment frequency, failed deployment recovery time, and change failure rate. To calculate these metrics manually using GitHub Actions in a GitHub repository, one needs to create actions that store data, such as log files, and then creates an action that processes this data to generate cumulative DORA metrics reports. The report provides insights into the team's performance over a specified period, allowing for identification of trends, areas for improvement, and measurement of the impact of changes made to development processes. The ultimate goal is to steadily improve software delivery performance over time.
