Hello Readers!! We are again back with an exciting topic i.e. Four Key Metrics. Through six years of research, the DevOps Research and Assessment (DORA) team has identified four key metrics that indicate software delivery performance.​ It provides a comprehensive view of DevOps performance and allows organizations to measure their progress over time.​

Four Key Metrics:

Organizations strive for success and growth in today’s fast-paced and competitive business landscape. To achieve these goals, it’s important to clearly understand your software delivery performance and identify areas for improvement. This is where Four key metrics come into play. In this blog post, we will explore four key metrics that can help you measure and enhance your software delivery performance.

Why we should use Four Key Metrics?

  1. It helps in measuring Software Delivery Performance.
  2. It helps in continuous Improvement​ in Delivery.
  3. It identifies bottlenecks and inefficiencies.
  4. It facilitates decision-making & identifies areas for optimization.
  5. It helps foster collaboration and accountability.
  6. It helps in aligning business and IT objectives.

1. Deployment Frequency

  • Deployment Frequency represents the frequency at which changes are released and deployed to the production environment. It measures software delivery throughput (velocity).
  • It is typically measured over a specific time period, such as per day, per week, or per month.
  • Deployment Frequency = Number of deployments / Unit of time​
On-Demand Multiple Deploys Per DayBetween once per week and once per monthBetween once per month and once every 6 monthsFewer than once per six months

How to increase deployment frequency?​

  • Implement Continuous Delivery practices​
  • Streamline release processes​
  • Automated Testing​
  • Monitoring and Observability​
  • Invest in infrastructure automation​
  • Focus on quality and reliability

2. Lead Time For Changes

  • It represents the amount of time taken by a commit to get into production.​ It measures software delivery throughput (velocity)​.
  • Lead Time For Changes = Time from commit to deploy​
Less than one hourBetween one day and one weekBetween one month and 6 monthsMore than six months

How to reduce the lead time?​         

  • Test Automation​
  • Trunk-based Development​
  • Minimize Batch size​
  • Continuous Improvement​
  • Improve code review efficiency​
  • Reduce manual intervention​
  • Foster collaboration and communication

3. Mean Time to Recover

  • It represents the amount of time taken by an organization to recover from a failure in production. It measures software delivery stability (quality)​.
  • Mean Time to Recover = Total downtime due to incidents / Number of incidents​
Less than one HourLess than one DayBetween one day and one weekMore than six months

How to minimize MTTR?​

  • Automated recovery processes​
  • Automated monitoring and alerting​
  • Incident prioritization​
  • Post-incident analysis​
  • Proactive system maintenance​
  • Testing and validation​

4. Change Failure Rate

  • It represents the frequency or percentage of failed deployments or releases within the software development and operations processes. It measures software delivery stability (quality)​.
  • Change Failure Rate = Number of failed changes / Total number of changes​
0% – 15%16% – 30%31% – 45%46% – 60%

How to minimize change failure rate?​  

  • Robust testing practices​
  • Code reviews​
  • Test Environments​
  • Configuration management​
  • Rollback and Recovery Strategies​
  • Change management process​
  • Monitoring and observability​
  • Change Review and Approval​
  • Learning from failures​


In this blog post, we got to know how four key metrics can be used to improve software delivery performance. Regularly monitoring these metrics and benchmarking them against industry standards or your own targets will enable you to identify areas for improvement and take proactive steps to enhance your performance.
