What are dora metrics (DevOps)?

DORA metrics, developed by the DevOps Research and Assessment (DORA) team. DORA statistics are key performance indicators used to measure the effectiveness and efficiency of a software delivery. Providing insights into the performance of DevOps practices and help organizations improve their software development and delivery processes. 

4 Primary DORA metrics:

1. Deployment Frequency: How often new code is successfully deployed to production.

  • Indicates the pace at which an organization is delivering new features, improvements, and fixes to users.

  • Measurement: Count the number of deployments to production in a given time period (e.g., daily, weekly, monthly).

2. Lead Time for Changes: the time it takes for a code change to go from commit to deployment in production.

  • Purpose: Reflects the efficiency of the development process and the speed at which an organization can respond to changes.

  • Measurement: Track the time from code commit to code being deployed in production.

3. Change Failure Rate: the percentage of deployments to production that cause a failure (e.g., a service outage, a bug requiring a hotfix).

  • Purpose: Indicates the stability and quality of the software being released.

  • Measurement: Calculate the ratio of failed deployments to total deployments over a period of time.

4. Mean Time to Recovery (MTTR / SLA): Measures the average time it takes to restore service when a failure occurs in production.

  • Purpose: Reflects the organization’s ability to quickly recover from failures and minimize downtime.

  • Measurement: Track the time from when a failure is detected to when it is resolved and normal service is restored.

Importance of DORA Metrics

  • Performance Benchmarking: DORA metrics allow organizations to benchmark their performance against industry standards and identify areas for improvement.

  • Data-Driven Decisions: By quantifying different aspects of the software delivery process, organizations can make informed decisions to enhance efficiency and effectiveness.

  • Continuous Improvement: Tracking these metrics over time helps organizations implement continuous improvement practices, fostering a culture of high performance and reliability.

  • Collaboration and Transparency: DORA metrics promote collaboration between development and operations teams by providing clear, objective data on the impact of their work.

Using DORA Metrics

Businesses use DORA metrics to:

  • Identify bottlenecks in the development and deployment process.

  • Implement and measure the impact of DevOps practices and tools.

  • Set goals and track progress toward improving software delivery performance.

  • Enhance team accountability and performance through regular monitoring and reporting.

DORA Statistics Example

A high-performing organization like PubNub has:

  • Deployment Frequency: Multiple times per day.

  • Lead Time for Changes: Less than an hour.

  • Change Failure Rate: Less than 5%.

  • MTTR: seconds

In contrast, a low-performing organization might see:

  • Deployment Frequency: Once a month or less

  • Lead Time for Changes: days or weeks

  • Change Failure Rate: above 15%.

  • MTTR: hours or days
