Calculating the mean is important because no two changes are the same and lead time will vary across different scopes and types of changes. 3/ Make sure you have an established workflow with DevOps teams before implementing the DORA model and all your CI/CD tools in place, so you can get the most out of applying these metrics. 2/ Having decentralized data – if you collect data from multiple areas in a disparate way, you can actually do more harm than good and become very overwhelmed and confused. After all, what good does a bunch of disconnected data do if you can’t put it all together in one context? Using a platform like Waydev is very useful as it reunites data collected from complex metrics in one single dashboard. This way you have all the information you need in one place, making it much easier to develop a plan for improvement.
Utilizing Waydev’s DORA metrics dashboard will provide valuable insights to inform decision-making and drive continuous improvement in software delivery performance. 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. As with any data, DORA metrics need context, and one should consider the story that all four of these metrics tell together. Lead time for changes and deployment frequency provide insight into the velocity of a team and how quickly they respond to the ever-changing needs of users. 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.
The Benefits of Assessing DevOps Performance with DORA Metrics
Over the past eight years, more than 33,000 professionals around the world have taken part in the Accelerate State of DevOps survey, making it the largest and longest-running research of its kind. Year after year, 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. A DORA survey is a simple way to collect devops dora metrics information around the four DORA metrics and measure the current state of an organization’s software delivery performance. Google Cloud’s DevOps Research and Assessments team offers an official survey called the DORA DevOps Quick Check. You simply answer five multiple-choice questions and your results are compared to other organizations, providing a top-level view of which DevOps capabilities your organization should focus on to improve.
Deployment Frequency refers to how often a team releases successful code into production. In other words, the DF metric assesses the rate of engineering teams deploying quality code to their customers, making this a very important means to measure teams’ performance. Lead time for changes measures the time needed to take a committed code to successfully run in production. Accelerated adoption of the cloud requires tools that aid in faster software delivery and performance measurements. Delivering visibility across the value chain, the DORA metrics streamline alignment with business objectives, drive software velocity, and promote a collaborative culture. To investigate this, we included operations questions in the survey for the first time this year.
Introducing the DevOps Awards
It should also display metrics clearly in easily digestible formats so teams can quickly extract insights, identify trends and draw conclusions from the data. Even though DORA metrics provide a starting point for evaluating your software delivery performance, they can also present some challenges. Metrics can vary widely between organizations, which can cause difficulties when accurately assessing the performance of the organization as a whole and comparing your organization’s performance against another’s. Each metric typically also relies on collecting information from multiple tools and applications.
Teams with high-quality documentation are 3.8x more likely to implement security best practices and 2.5x more likely to fully leverage the cloud to its fullest potential. Because there are several phases between the initiation and deployment of a change, it’s wise to define each step of the process and track how long each takes. Examine the cycle time for a thorough picture of how the team functions and further insight into where they can save time. Time to restore service is the amount of time it takes an organization to recover from a failure in production. In the value stream, “Lead time” measures the time it takes for work on an issue to move from the moment it’s requested (Issue created) to the moment it’s fulfilled and delivered (Issue closed). Organizations vary in how they define a successful deployment, and deployment frequency can even differ across teams within a single organization.
Why Use DORA Metrics?
Medium performers fall between one week and one month, while low performers take between one and six months. Applying the same metrics and standards blindly without taking into account the context of a particular software product requirements or team needs is a mistake. Instead of finding ways of improving performance, doing so will only bring more confusion. The goal here is to assess how efficient teams are in solving issues when they arise; identifying the problem fast and responding as quickly as possible are indicators of high-performing DevOps teams.
- DORA classifies elite, high, and medium performers at a 0-15% change failure rate and low performers at a 46-60% change failure rate.
- Aggregation hides outliers that could spark a conversation that leads to improvement.
- The ability to have a fluid definition of teams using multiple criteria such as organization, project, issue tag, and such is critical because ultimately metrics have to be measured at the level where change can happen to improve it.
- The mean time to recover metric measures the amount of time it takes to restore service to your users after a failure.
- You can still use the mean time to compare performance to the industry performance clusters.
MTTR is calculated by dividing the total downtime in a defined period by the total number of failures. For example, if a system fails three times in a day and each failure results in one hour of downtime, the MTTR would be 20 minutes. In the following sections, we’ll look at the four specific DORA metrics, how software engineers can apply them to assess https://www.globalcloudteam.com/ their performance and the benefits and challenges of implementing them. In the Four Keys scripts, Deployment Frequency falls into the Daily bucket when the median number of days per week with at least one successful deployment is equal to or greater than three. To put it more simply, to qualify for “deploy daily,” you must deploy on most working days.

Teams that prioritize both delivery and operational excellence report the highest organizational performance. For software leaders, Lead time for changes reflects the efficiency of CI/CD pipelines and visualizes how quickly work is delivered to customers. Over time, the lead time for changes should decrease, while your team’s performance should increase. In GitLab, Lead time for changes is measure by the Median time it takes for a merge request to get merged into production (from master). Software leaders can use the deployment frequency metric to understand how often the team successfully deploys software to production, and how quickly the teams can respond to customers’ requests or new market opportunities.
The service management model uses the principles of the service approach in organizing the daily work of employees. These rules, agreed upon both domestically and internationally, will allow periodic monitoring of the activities of its members, including in accordance with the rules of business ethics. The work of such an association will provide an opportunity at an early stage to identify the incompetence of counterparties and develop measures to counter the malicious intent of unscrupulous partners.

Lead time is calculated by measuring how long it takes to complete each project from start to finish and averaging those times. Baselining your organization’s performance on these metrics is a great way to improve the efficiency and effectiveness of your own operations. It then aggregates your data and compiles it into a dashboard with these key metrics, which you can use to track your progress over time.
What we’re measuring here is referred to as ‘burn rate’—how much of our error budget (2% of errors over 24 hours) we are eating up with the current SLI metic. The window we measure for our alert is much smaller than our entire SLO so when the SLI has moved back within compliance of a threshold, another alert fires, indicating the incident has cleared. Once we have the above metric and labels created from our Cloud Build log we can access it in Cloud Operations Metrics explorer via the metric label ‘logging/user/dorametics’ (‘DoraMetrics’ was the name we gave our log-based metric).
Measuring DevOps with the DORA metrics
Assuming these times could be queried, MTTR could be determined by the average time between the reported and resolved timestamps of the issues. 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. You can calculate the lead time for changes by averaging the lead time for changes over a period of time for various commits.
