Low deployment frequency typically indicates delays in the delivery pipeline—either before merging code into production or during the deployment step. Tracking and measuring the right metrics can guide teams along the path to improving their DevOps and engineering performance, as well as help them create a happier and more productive work environment. If you adopted some of the technical, cultural, and process capabilities of DevOps, you may wonder whether your hard work is paying off. Adopting practices, learning tools, and building deployment pipelines takes time and effort. Now you need a way to see if this is helping you achieve your goals. Alongside deployment frequency metrics, organizations are also rated at low, medium, high, and elite levels of maturity.

While setting the improvement goals, focus on your product and its growth, as well as the growth of your team and improvement of the processes. Start gathering data, track the metrics for the first period, and then analyze what you have to improve. Change in Failure Rate is calculated by counting the number of deployment failures and dividing it by the total number of deployments. The team’s goal should be to reduce Lead Time for Changes and react to issues in a timely manner. Lead Time for Changes is an indicator of how quickly a team responds to needs and fixes. It represents the efficiency of the process, code complexity, and team’s capacity.
This is why it’s critical that your team has a culture of shipping lots of changes quickly so that when an incident happens, shipping a fix quickly is natural. The time to detection is a metric in itself, typically known as MTTD or Mean Time to Discovery. If you can detect a problem immediately, you can take MTTD down to practically zero, and since MTTD is part of the calculation for MTTR, improving MTTD helps you improve MTTR. Lead Time for Changes – average number of days from the first commit for a pull request until the deployment date for the same pull request. You can use filters to define the exact subset of applications you want to measure.
And this is why they value robust observability platforms, like Sumo Logic, to help them measure their objectives and ensure they’re on track to meeting their KPIs, deadlines, and long-term strategies. If a higher measure of lead time shifts, DevOps teams can streamline processes, and break down products and features into smaller, more manageable code. The DORA research results and data have become a standard of measurement for those people who are responsible for tracking DevOps performance in their organization. Engineering and DevOps leaders need to understand these metrics in order to manage DevOps performance and improve over time. While DORA metrics are a great way for DevOps teams to measure and improve performance, the practice itself doesn’t come without its own set of challenges.
How do you calculate Lead Time for Changes?
More successful DevOps teams deliver smaller deployments more frequently, rather than batching everything up into a larger release that is deployed during a fixed window. High-performing teams deploy at least once a week, while teams at the top of their game — peak performers — deploy multiple times per day. Change failure rate is the rate at which deployments to production lead to incidents. While MTTR measures your team’s ability to mitigate incidents, change failure rate measures your team’s ability to avoid issues from even reaching production. Much of the CI/CD development pipeline is about managing speed versus stability. If you overemphasize speed, to improve deployment frequency and lead time for changes, you may fail to realize the impact on the stability metrics.
At a summer conference on Agile a few years prior to the COVID pandemic, I attended a panel discussion about productivity metrics in engineering. The attendees were a diverse group of IT leaders from various industries, including eCommerce and software development. Despite their different backgrounds, they all agreed that the measurement of engineering productivity “depends” on various factors, such as the company’s maturity. By measuring the velocity of development and stability of deployment and the product itself, teams are motivated to improve their results during subsequent iterations. Accelerate, the DORA team identified a set of metrics which they claim indicates software teams’ performance as it pertains to software development and delivery capabilities.
How to get maximum value from service level objectives (SLOs)
Flow efficiency measures the ratio of active time to total flow time to identify waste in the value stream. MTTR begins the moment a failure is detected and ends when service is restored for end users — encompassing diagnostic time, repair time, testing and all other activities. 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.
When performance is measured, there is a big chance it will be gamed. This means that people who feel responsible for a certain metric will adjust their behavior to improve the metric https://globalcloudteam.com/ on their end. While this can have a distorting effect in various contexts, it is actually the desired effect in DevOps – it helps to eradicate inefficient processes and reduces waste.

- DORA metrics and Flow metrics address this need by providing objective data to measure the performance of software delivery teams and drive product improvement.
- It provides insight into how long it takes for teams to complete their work and how quickly they deliver value to their customers.
- By changing your batch size to be as small as possible and shipping as often as possible, you’re actually reducing your overall risk.
- DORA uses the four key metrics to identify elite, high, medium, and low performing teams.
- To retrieve metrics for lead time for changes, use the GraphQL or the REST APIs.The definition of lead time for change can vary widely, which often creates confusion within the industry.
A higher deployment frequency means you can get feedback sooner and iterate faster to deliver improvements and features. GitLab measures this as the number of deployments to a production environment in the given time period. Organizations with slow production cycles have low deployment frequency and high lead time for changes. Often, we can improve throughput by optimizing continuous integration and continuous delivery (CI/CD), identifying organizational problems, speeding up test suites, and reducing deployment friction. As a proven set of DevOps benchmarks, DORA metrics provide a foundation for this process.
Each metric could proxy for more factors, so consider the ones you use carefully. You can use the SPACE framework at an individual, team, and system level, and each DORA metric could fit into one of the SPACE framework categories. The benefit of using the SPACE framework is that you tackle productivity from many angles rather than looking at a single metric. Adopting SRE across a company is a journey, and the report indicates a ‘J-curve’ pattern to seeing results. In the initial adoption phase, there will be few results while teams learn new processes and implement systems. At a certain threshold, SRE yields tangible improvements to reliability as the curve trends upwards.
Go beyond DORA metrics
When you measure and track DORA metrics over time, you will be able to make well-informed decisions about process changes, team overheads, gaps to be filled, and your team’s strengths. These metrics should never be used as tools for criticism of your team but rather as data points that help you build an elite DevOps organization. Next up is the change failure rate, or, simply stated, a measurement of the percentage of deployments that cause failures in production.
When companies have short recovery times, leadership has more confidence to support innovation. This creates a competitive advantage and improves business profits. On the contrary, when failure is expensive and difficult to recover from, leadership will tend to be more conservative and inhibit new development.

In order to improve a high average, teams should reduce deployment failures and time wasted due to delays.
There is a need for a clear framework to define and measure the performance of DevOps teams. In the past, each organization or team selected its own metrics, making it difficult to benchmark an organization’s performance, compare performance between teams, or identify trends over time. The Mean Time to Recovery measures the time it takes to restore a system to its usual functionality.
What is reliability management?
Mean time to resolve is the time to detect, diagnose, and fix an incident, including the time required to improve long-term performance. It measures the time required to fix an issue in production, as well as the time required to implement additional measures to prevent the issue from occurring again. Mean time to recovery is the time between the start of an issue in production and the end of the incident in production. Production failures will inevitably occur at every engineering organization.

In order to improve their performance in regards to MTTR, DevOps teams have to practice continuous monitoring and prioritize recovery when a failure happens. It is also helpful to establish a go-to action plan for an immediate response to a failure. For example, mobile applications which require customers to download the latest Update, usually make one or two releases per quarter at most, while a SaaS solution can deploy multiple times a day. By establishing progress, this evidence can motivate teams to continue to work towards the goals they’ve set. DORA benchmarks give engineering leaders concrete objectives, which then break down further into the metrics that can be used for key results. Thus, delivering defect-free software at speed makes all the difference.
By combining these metrics, teams can understand how changes in product stability affect development throughput, or vice versa. The world-renowned DORA team publishes the annual State of DevOps Report, an industry study surveying software development teams around the world. Over the last few years, DORA’s research has set the industry standard for measuring and improving DevOps performance. DORA metrics provide a way to quantify the success of DevOps methodologies.
To improve visibility, engineering managers and leaders should consider other metrics beyond the DORA metrics as well. Create runbooks and continuously update documentation so anyone on a team can respond to an outage effectively. The goal is to reduce dependencies on only a few team members during incidents and empower every engineer to assist if needed.
Every year, the State of DevOps report is released with an updated research model. This enables the project to keep up to date with the industry as new methodologies and technologies are embraced. It provides an independent assessment of how organisations deliver software through four key metrics. The goal of this research is to determine practices that drive software delivery excellence and demonstrate how this is key to organisational success. Lead time for changes isn’t a static metric; like deployment frequency, you must select over what time period you’re measuring your lead time, and take the mean number of commits over several periods.
To improve lead time to changes, DevOps teams must include automated testing in the development process. Your testing team can educate your Dev teams to write and automate tests. The change lead time can also be reduced by introducing more regression unit tests, so any regressions introduced by code changes can be identified as early as possible. The DORA team has conducted research for seven years to identify the key metrics that precisely indicate the performance of the DevOps initiative. During the research, the team collected data from over 32,000 professionals worldwide and analyzed it to gain an in-depth understanding of DevOps practices and capabilities that drive performance. Change Failure Rate measures the percentage of deployments causing failure in production ﹣ the code that then resulted in incidents, rollbacks, or other failures.
In other terms, it measures how often a company deploys code for a particular application. As the name already suggests, Deployment Frequency refers to the frequency of successful software releases to production. Low performance on this metric can inform teams that they may need to improve their automated testing and validation of new code. Another area to focus on could be breaking changes down into smaller chunks, and creating smaller pull requests , or improving overall Deploy Volume. After the insight of six years of research, the DevOps Research and Assessment group published its report that identified the four metrics to measure the performance of DevOps teams.
While a DORA survey can provide generalized guidance, many organizations additionally enlist the help of third-party vendors to conduct personalized assessments. These more closely examine a company’s culture, practices, technology and processes to identify specific ways to improve its DevOps team’s productivity. Swarmia gives you visibility into deployment frequency and batch size (i.e. the lines of code changed per pull request).
