How to measure DevOps mean time to recovery (MTTR)

Mean Time to Recovery (MTTR) is a key performance metric in software delivery, measuring the time it takes to restore a system after a fault. While MTTR is popularized by the DevOps Research and Assessment (DORA) metrics for its utility in industry research, it can be misleading for teams if used improperly, as it averages out critical incident details. To improve incident management, it is recommended to use detailed metrics and visualizations like scatter plots or box-and-whisker charts to capture trends and outliers. The SPACE framework is suggested as a more holistic approach to incident response, emphasizing satisfaction, performance, activity, communication, and efficiency. By using these diverse metrics, organizations can enhance their incident management processes and system stability more effectively than relying on MTTR alone. Additionally, conducting incident retrospectives and reviews shortly after incidents can help capture learnings and foster continuous improvement by addressing systemic issues rather than focusing solely on individual errors.
