The Accelerate Book, The Four Key Devops Metrics & Why They Matter

They form an excellent foundation for your metrics initiatives, helping improve your existing DevSecOps efficiency while also offering a map? But as with any challenge, success can only be recognised when there is a benchmark to measure against. And the truth for many organisations is that CIOs are often flying blind on the ROI from their total investment in software development, IT operations, and application security. Plandek is a global leader in software delivery metrics and analytics, recognised by Gartner as a top nine global vendor in their DevOps Value Stream Management Market Guide . Taking all your workflows over a period it calculates the percentage that ended in failure/require remediation (e.g., require a hotfix, rollback, fix forward, patch). Understanding the frequency of how often new code is deployed into production is critical to understanding DevOps success. Many practitioners use the term “delivery” to mean code changes that are released into a pre-production staging environment, and reserve “deployment” to refer to code changes that are released into production.

They can shorten this process with real-time data flows, better context, and robust monitoring using tools like DataDog and Monte Carlo. Mean time to recovery is the time between the start of an issue in production and the end of the incident in production. The DORA metrics use the first commit as the starting point because it can be easily and objectively measured using source control data and it captures most of the development work required for a task. There are several ways to calculate lead time depending on how your team marks the beginning and end of each unit of work. Moreover, lead time can be calculated for any unit of work, such as a story, task, or feature. It’s also worth considering when the speed or frequency of delivery is a cost to its stability.

We find that for Haystack teams, customers of ours, the average team has a cycle time of less than three days. The elite teams will usually get this down considerably more than that, but at least an average is three days for performance of cycle time. Now, this is formed of a variety of different leading indicators. So the cycle time itself, it measures that entire time for implementation, test, and delivery of code, but really there is development time, which is time spent developing something, there is also review time. Review time is the things which are to do with once someone’s got a pull request, the first response time, then you’ve got the rework time, and idle completion time. So you have two leading indicators and things break down even more. The idea comes from lean manufacturing practices, in which every step of the physical process is monitored to ensure the greatest efficiency.

Four Critical Devops Metrics

It’s about the developers wanting to improve their team’s efficiency and using metrics to know whether they’re successful in their improving efforts. Typically, this deep-dive approach requires organizations to acknowledge any struggles at the deployment phase. Deployment can be tricky for many organizations that haven’t flushed out DevOps best practices. An important tech marker of this step is version control. Teams implement it and other practices that are considered early stages of continuous integration.

“Deployment frequency be a vanity metric if people focus on it too much there is something transformative for the business moving from monthly to every couple of days, it’s a really big jump. Almost everyone is using the cloud, but most people are using it poorly. Organizations should not expect to become highly evolved just because they use cloud and automation.

Click the name of a node to view its node statistics over time. These represent high-level statistics collected from Elasticsearch that provide a good overview of health. If you use Filebeat to collect log data from this node, you can also see its recent logs. The panel at the top shows the current cluster statistics, the charts show the search and indexing performance over time, and the table at the bottom shows information about any shards that are being recovered. If you use Filebeat to collect log data from this cluster, you can also see its recent logs. Elite teams have a clear understanding of who does what and automates as much as possible. And we’re better when we share our insights and our ideas with one another.

In this respect, failure could include expected outages but also hard performance degradations, or other unplanned failures. If you can deploy multiple times per day, your deployment must be automated and efficient, so that it is possible to deliver changes without any artificial obstacles. I would say that this is in fact, a quite logical proxy for “how fast customers gets value”. Mean change lead time is calculated by tracking the time between each code commit to the code being delivered in production and calculating an average. Measuring the performance of software engineering teams has long been seen as a complicated, daunting task. This is particularly true as software becomes more complex and more decentralized. Delivering updates, new features, and software improvements with greater efficiency and accuracy is crucial to building and maintaining a competitive advantage.

When this occurs, organizations are at a stage where they share ideas, technology, knowledge, and metrics. Otherwise, your team might quickly be buried under a pile of requests they can’t dig out of, leading to long waits for issues to be resolved or damage to the user experience. Monitoring and analytics help everyone involved to keep moving in the right direction at all times, wherever they are located in the world. In the past, in previous years, we asked questions about your operational performance in terms of availability. But this year, we’ve refined our approach and gone deeper with the research to move from availability to reliability. Now, a subtle change in language, but as we know, language is important. But that subtle change is really more to help everyone consider not just is the application available, but availability is really a component of reliability.

And importantly, how to identify where they should focus their improvement work. DORA eventually in 2018 was acquired by Google Cloud, and we’ve continued to expand on that research, and continue to work together to bring the findings of that research and practical implementations to our customers.

But watch out for the major misconception that this is achieved purely from ‘tooling’. After all, you can’t buy tools and simply expect them to fix your problems – if you buy a drill, the shelves don’t go up on their own! First, you must understand the process (how to level the boards, where to use wall anchors, and so on.). In our developer world, it’s important to understand the tools and the processes that come along with it. Finally, Humble talked about how teams achieve outcomes not individuals, which is why team and organizational culture are what make or break these elite DevOps performers. Only 29 percent of respondents for Google’s survey met all five requirements. Unsurprisingly these lined up with DevOps performance.

Deployment Frequency

We dig into different capabilities that teams should invest in. Now, those capabilities might be technical Follow-the-sun capabilities, but they’re also process capabilities, measurement capabilities, and cultural capabilities.

So what we do is we look at how are they doing across each of those metrics? So, at a very high level, I’ll tell you a little bit about the elite performers and the low performers. On that deployment frequency, elite performers are able to deploy on demand. But a low performer in 2021, will do fewer deployments than once per six months. So it might take seven, eight months, maybe yearly, for them to do a single code deployment. The flip side of that, of course, is our time to restore service or change fail rate.

There’s a phrase that goes out there and comes from John Allspaw about mean time to recovery is more important than mean time between failures for most failures. The point being that by putting stuff into production, it’s more important that you can realize that something’s gone wrong and fix it, than it is to prevent the failures in the first place. The research identified that just Four Key Metrics distinguish the performance of various organisations. These “North Star” metrics serve as indicators of overall software engineering health.

  • When this occurs, organizations are at a stage where they share ideas, technology, knowledge, and metrics.
  • Nathen Harvey, Developer Relations Engineer at Google, has built a career on helping teams realize their potential while aligning technology to business outcomes.
  • But comparing our metrics to others gives us the confidence to keep the tempo.
  • High-performing teams typically measure lead times in hours, versus medium and low-performing teams who measure lead times in days, weeks, or even months.

Deployment frequency is the number of deployments over a period of time. It could be measured through a range of ways, such as via an automated deployment pipeline, API calls, or manual scripts.

Changes that result in a rollback, in production failing, or in production having a bug all contribute to this metric. Mean time to recovery, also known as mean time to restore, measures the average amount of time it takes the team to recover from a failure in the system. One of the most important and well-known results of that was done by the DevOps Research and Assessment organization, known commonly as DORA. They surveyed thousands dora metrics of DevOps engineers and leaders over six years, coming up with a set of four metrics that were considered critical to the success of software development projects. The most common way of measuring lead time is by comparing the time of the first commit of code for a given issue to the time of deployment. A more comprehensive method would be to compare the time that an issue is selected for development to the time of deployment.

When anything gets measured, it will likely be gamed. That is, people will change behavior to optimize that which is measured. Many times this can have a negative, distorting effect on what a development team does. Normally, this metric is calculated by counting the number of times a deployment results in a failure and dividing by the number of total deployments to get an average number. This metric is important because all time spent dealing with failures is time not spent delivering new features and value to customers. Obviously, lowering the number of problems in your software is desirable.

So when you make a push into production, how frequently are you shouting out an expletive? Someone had to get involved in that deployment process. We know that if we want to improve our organizational performance, software delivery and operations performance drives organizational performance. The faster that changes can be rolled back, or systems can be manually or automatically adapted to restore services, the higher the performance of the team and the better the customer experience and value delivered. Platform engineering is the discipline of designing and building toolchains and workflows that enable self-service capabilities for software engineering organizations in the cloud-native era. Platform engineers provide an integrated product most often referred to as an “Internal Developer Platform” covering the operational necessities of the entire lifecycle of an application.
