Learn how the Four Keys open source project lets you gauge your DevOps performance according to DORA metrics. In the next sections below, you will learn more about the four DORA metrics and why they are so useful in value stream management. DORA metrics are great tools to use, but as with any form of measurement, there are some considerations to keep in mind. If we go back to the customer who needs an urgent fix on their application, do you think they’re more likely to work with a high or low-performing team? While the answer might be based on many factors, it seems most likely that a customer would choose the quicker turnaround time and stick with the high-performing team. Before we outline the four key DORA metrics in DevOps, let’s cover a brief history lesson to understand where these metrics came from.
In essence, it measures the reliability of your software development and deployment processes. Measuring and optimizing DevOps practices improves developer efficiency, overall team performance, and business outcomes. DevOps metrics demonstrate effectiveness, shaping a culture of innovation and ultimately overall digital transformation. Born from frustration at the silos between development and operations teams, the DevOps philosophy encourages trust, collaboration, and the creation of multidisciplinary teams. The startup identified four key metrics — the “DORA Metrics” — that engineering teams can use to measure their performance in four critical areas.
Integrated Development Environments: Basic Functions and Benefits for Business
The four metrics used are deployment frequency (DF), lead time for changes (MLT), mean time to recovery (MTTR), and change failure rate (CFR). This metric measures the time that passes for committed code to reach production. While Deployment Frequency measures the cadence of new code being released, Lead Time for Changes measures the velocity of software delivery. It is used to get a better understanding of the DevOps team’s cycle time and to find out how an increase in requests is handled.
This trends towards larger batches deployed less often and feedback that comes far too late. To get the most out of DORA metrics, engineering leads must know their organization and teams and harness that knowledge to guide their goals and determine how to effectively invest their resources. As with lead time for changes, you don’t want to implement sudden changes at the expense of a quality solution. Rather than deploy a quick fix, make sure that the change you’re shipping is durable and comprehensive.

On the other hand, mean time to recovery and change failure rate indicate the stability of a service and how responsive the team is to service outages or failures. Over the past seven years, more than 32,000 professionals worldwide have taken part in the Accelerate State of DevOps reports, https://www.globalcloudteam.com/ making it the largest and longest-running research of its kind. Year over year, the Accelerate State of DevOps reports provide data-driven industry insights that examine the capabilities and practices that drive software delivery as well as operational and organizational performance.

DORA Metrics to Measure DevOps Performance
While they might not always be avoidable, what’s important is how you respond to them. The time to recover or restore service measures how long it generally takes to restore service when an incident such as an unplanned outage occurs. The goal of optimizing time to recovery is to minimize downtime and prepare to diagnose and correct issues when they occur. MTTR is important for organisations that rely on technology to provide their services, as it can impact the availability and reliability of those services.
This allows developer teams to get a sense of a dip in performance early on so they can mitigate it. Alternately, if performance is low, teams will see early signs of progress before the buckets are updated.

In order to improve a high average, teams should reduce deployment failures and time wasted due to delays. They consistently and regularly publish their findings and insights to evolve and drive DevOps teams.

In recent years, value stream management has become an important part of software development. In this context, DORA metrics play a big role as they show what kind of value is delivered dora metrics devops to the customer and what performance level is necessary to reach desired business outcomes. Thus, once DevOps teams use DORA metrics, they usually see an increase in value over time.
How an organization performs against these measures predicts performance against its broader goals. There are many definitions of ‘lead times’ in software delivery and manufacturing, so it’s worth being specific about the DevOps definition. Lead time for changes is the time it takes for a code change to reach the live environment.
The Four Key DORA Metrics and Industry Values That Define Performance
Deployment frequency was all about the speed of deploying code changes in production, and change failure rate emphasizes the quality of the changes being pushed to production. It’s important to note that a failure in production can be different depending on the software or application. When using this metric, it’s essential to define what a failure is in your work for your team. DevOps Research and Assessment (DORA) is a DevOps research team that Google acquired in 2018. DORA uses data-driven insights to deliver best practices in DevOps, with an emphasis on helping organizations develop and deliver software faster and better. Today, DORA continues to partner with the Google Cloud team to release DevOps research and reports to improve software delivery within organizations.
- Your work-tracking tools may have a feature to link a bug request to the original change.
- We use these timestamps in our cloud function to calculate the time to resolve the issue and then output it to the logs.
- If deployment frequency is high, it might reveal bottlenecks in the development process or indicate that projects are too complex.
- It’s also useful to review restore times for change failures separately from those caused by unexpected Production environment issues.
- On the other hand, mean time to recovery and change failure rate indicate the stability of a service and how responsive the team is to service outages or failures.
It is typically measured from the time a code change is committed to a version control system to the time it is deployed in a production environment. The general trend is that a few years ago, many organizations viewed DevOps as a promising experiment rather than a mainstream approach to software development. DoRa Metrics in software DevOps are now a proven and powerful set of development and deployment practices and tools to accelerate new product releases and improve productivity.

Your mean time to recovery is the average time between a failure and full recovery, whether due to a code change or something else. You can collect this from your work-tracking tools by marking work items as a Production fix and measuring the time it takes to complete the work. If you’re in an early stage of product development, consider encouraging risk-taking and experimentation by aiming for a higher change-failure rate. Where people depend on the software, you’ll want to achieve a lower change failure rate. Your deployment pipeline (and not policy constraints) should be the primary mechanism for reducing failures introduced by changes to the software.
