Mean Time to Restore
Mean Time to Restore (MTTR) represents the average time taken to resolve a production failure/incident and restore normal system functionality each week.
The way a team tracks production failure (CFR) defines how MTTR is calculated for that team. If a team considers a production failure as :
Pull Request tagging to track a deployment that needs a rollback or a hotfix In such a case, MTTR is calculated as the time between the last deployment till such a Pull Request was merged to main/master/production
Tickets tagging for high-priority production incidents In such a case, MTTR is calculated as the average time such a ticket takes from the ‘In Progress’ state to the ‘Done’ state
CI/CD integration to track deployments that failed during the production workflow In such a case, MTTR is calculated as the average time between that deployment failure to its being successfully deployed

💡 Here is an important tip on how you can use MTTR on the Typo dashboard
Benchmarking MTTR helps you identify areas for improvement in incident management, such as optimizing response times, enhancing problem-solving capabilities, and streamlining communication and collaboration among team members.
How does measuring MTTR help in improving the Engineering teams' efficiency?
Measuring "Mean Time to Restore" (MTTR) provides crucial insights into an engineering team's incident response and resolution capabilities. It helps identify areas of improvement, optimize processes, and enhance overall team efficiency. Here are some specific insights that can be gained from measuring MTTR and how they can be used to improve engineering team efficiency:
Incident Response Effectiveness: MTTR reflects the team's ability to detect, diagnose, and resolve incidents promptly. A lower MTTR indicates a more effective incident response process.
Root Cause Analysis: MTTR helps in identifying recurrent or complex issues that require root cause analysis. Teams can focus on addressing underlying causes to prevent similar incidents in the future.
Continuous Improvement: Tracking MTTR over time allows teams to evaluate the effectiveness of process improvements and incident management practices.
Impact of Automation: Measuring MTTR helps assess the impact of automation on incident resolution. Automated responses to incidents can significantly reduce restoration times.
