Use Four Keys metrics like change failure rate to measure your DevOps performance Google Cloud Blog

By using Waydev’s DORA metrics dashboard, you can pull these metrics automatically in a single dashboard with no manual input, thanks to our CI/CD integrations, such as GitHub Actions, Jenkins, and CircleCI. Doing so will provide a clear overview of your team’s delivery performance over time, generate reports that will drive your decision-making skills, and identify areas of improvement. 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. Earlier, we mentioned DORA metrics and their importance in value stream management.

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. By spotting specific periods when deployment is delayed, you can identify problems in a workflow ﹣ unnecessary steps or issues with tools. You can also recognize problems like staff shortage or the need for longer testing time. The metrics reflect key areas that influence performance and equip engineers with detailed insights.

Optimize engineering velocity

In software development, it’s nearly impossible to see how each piece of the dev process fits together without a reliable set of data points to track across teams. This metric captures the percentage of changes that were made to a code that then resulted in incidents, rollbacks, or any type of production failure. Thus, Change Failure Rate is a true measure of quality and stability while the previous metrics, Deployment Frequency and Lead Time for Changes don’t indicate the quality of software but just the tempo of software delivery. Change Failure Rate is calculated by counting the number of deployment failures and then dividing it by the total number of deployments. When tracked over time, this metric provides great insight as to how much time is spent on fixing errors and bugs vs. delivering new code. Needless to say, a DevOps team should always strive for the lowest average possible.

He explains what DORA metrics are and shares his recommendations on how to improve on each of them. 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. With Four Keys, our solution was to create a generalized pipeline that can be extended to process inputs from a wide variety of sources. Any tool or system that can output an HTTP request can be integrated into the Four Keys pipeline, which receives events via webhooks and ingests them into BigQuery.

DevOps Research and Assessment (DORA) metrics

Of course, choosing the right metrics matter, and we advocate using DORA metrics or Accelerate metrics because studies have proven that they affect softtware delivery performance. If you’re curious about how Sleuth compares with other metrics trackers in the market, check out this detailed comparison guide. 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. There is a need for a clear framework to define and measure the performance of DevOps teams.

That way, engineering teams can have complete visibility into how their DevOps pipeline is moving, the blockers, and what needs to be done at individual contributor and team level. The best way to avoid this pitfall is to use additional DevOps metrics like PR size, sprint velocity, and developer well-being for complete factual visibility into the overall development cycle. DORA offers one piece of the SDLC puzzle, the rest is something teams need to figure out as they evolve- based on size, complexities and product development.

Automatic CI/CD tools data aggregation for fast delivery

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. It is calculated by counting the number of deployment failures and then dividing it by the total number of deployments.

DORA metrics measure the effectiveness of your value stream management efforts, enabling you to increase your business values. A precise framework is required to establish and measure the performance of DevOps teams. Previously, each company or team chose its measures, making it difficult to assess an organization’s success, compare team performance or detect long-term trends. To calculate time to restore service, you’ll need to have a shared understanding of what incidents you’re including as part of your analysis.

Change Failure Rate (CFR)

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. They enable leaders and STOs to highlight the main aspects, suggest improvements and focus on improving efficiency.

Their proposed models have proven to optimize OKR for DevOps teams’ performance and drive the success of tech organizations across all industries. Over the years, many industry experts have tried to devise ways of predicting performance with more or less success. One widely-accepted conclusion is that to improve a process, you first need to be able to define it, identify its end goals, and have the capability of measuring the performance. Improving software delivery performance is one 4 dora metrics of the main goals and OKR DevOps, and metrics such as the DORA metrics can be used to measure and optimize the performance of the software delivery process. Lead time has been a key metric for decades in organizations that practice lean software development and leverage proven agile values, principles, and practices. Within the context of DORA metrics, lead time refers to the average amount of time that elapses between committing new code and releasing that code into production.

How do you calculate Lead Time for Changes?

Rather than deploy a quick fix, make sure that the change you’re shipping is durable and comprehensive. You should track MTTR over time to see how your team is improving and aim for steady, stable growth. Technically, the key here is to get the developer involved in the production ideally doing the deployment. 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. The ability to recover quickly from a failure depends on the ability to quickly identify when a failure occurs, and deploy a fix or roll-back any changes that led to the failure.

  • This will enable you to see potential weak areas that are affecting productivity and help you make data-driven executive decisions.
  • It measures how often a company successfully deploys code to production for a particular application.
  • Outcome metrics, on the other hand, measure the overall performance and success of the process, including factors like customer satisfaction with the product and the frequency of successful deployments.
  • Measuring the four key metrics of DevOps, which were original specified within the Accelerate book, helped a company to assess the performance of their software delivery process.
  • Mean Time to Recovery indicates the time it takes to restore service in downtime.

They provide a clear framework to engineering leaders and DevOps teams to measure software delivery through reliability and speed. The change failure rate metric measures the percentage of changes that fail in production. It’s calculated by the number of deployment failures / total number of deployments. In essence, it measures the reliability of your software development and deployment processes. The ability to measure and track performance across lead time for changes, change failure rate, deployment frequency, and MTTR allows teams to accelerate velocity and increase quality.

Challenges in Implementing DORA Metrics

DORA uses its metrics to identify Elite, High, Medium, and Low performing teams. They claim that Elite teams are twice as likely to meet or exceed the performance goals of the organization. DORA metrics give a high-level view of a team’s performance, allowing to assess how well the team balances speed and stability and spot areas for improvement. For software leaders, Time to restore service reflects how long it takes an organization to recover from a failure in production. Low Time to restore service means the organization can take risks with new innovative features to drive competitive advantages and increase business results. The time it takes to restore a failure in production, where a failure can be an unplanned outage or a service failure.
