    Devops Research And Assessment Dora Key Metrics Api

    The Four Keys setup script uses a DataStudio connector, which allows you to connect your data to the Four Keys dashboard template. The dashboard is designed to give you high-level categorizations based on the DORA research for the four key metrics, and also to show you a running log of your recent performance. 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 DORA, MTTR is one measure of the stability of an organization’s continuous development process and is commonly used to evaluate how quickly teams can address failures in the continuous delivery pipeline. A low MTTR indicates that a team can quickly diagnose and correct problems and that any failures will have a reduced business impact.

    The data is then aggregated and compiled into a dashboard with data visualizations of the four key DORA metrics, which DevOps teams can use to track their progress over time. DORA metrics are a framework of performance metrics that help DevOps teams understand how effectively they develop, deliver and maintain software. They identify elite, high, medium and low performing teams and provide a baseline to help organizations continuously improve their DevOps performance and achieve better business outcomes.

    Enthusiastic teams have a tendency to aspire for grandiose goals like “Zero defects in Production”. Though admirable; it is best to set goals that are Specific, Measurable, Achievable, Realistic and Time-bound at this stage. Events are any occurrence in your development environment that can be measured, such as a pull request or new issue. Four Keys defines events to measure, and you can add others that are relevant to your project. We setup Azure Monitor alerts on our resources, for example, on our web service, where we have an alerts for HTTP500 and HTTP403 errors, as well as monitoring CPU and RAM. If any of these alerts are triggered, we capture the alert in an Azure function, and save it into a Azure table storage, where we can aggregate and measure the time of the outage.

    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 DoRa Metrics software DevOps a top-level view of which DevOps capabilities your organization should focus on to improve. Mean lead time for changes measures the average time between committing code and releasing that code into production.

    What Are Dora Metrics?

    Similar to Change Failure Rate, MTTR can be complex to measure. At the risk of oversimplifying this nuanced process, teams may rely on monitoring and observability platforms to capture the start and end times of an incident. Depending on the nature of the issues; Application Insights within Azure Monitor or even PagerDuty can be leveraged to measure MTTR. Deployment Frequency is by far the easiest metric to measure. This information could be gathered manually at the team level, or in an automated fashion from the deployment pipeline.

    An organization’s particular cultural processes — such as separate test teams or shared test environments — can impact lead time and slow a team’s performance. Plug in your CircleCI account, start measuring and optimizing software delivery performance. Measure your teams’ software delivery velocity and throughput, generate reports with actionable insights and identify improvement opportunities. It can also be broadly measured with the help of the deployment pipeline.

    Keep in mind that anytime you measure someone’s work, and especially if you are using these metrics for financial incentives, it is human nature to draw the shortest path to the goal. The late, great, Abel Wang, shared a graphic a few years ago that highlighted learnings the Azure DevOps team had found with their metrics. In the Four Keys pipeline, known data sources are parsed properly into changes, incidents and deployments.

    I don’t know any of these people personally, but none of this wouldn’t have been possible without their hard work and visionary innovation. Every organization has a somewhat unique set of actions that must occur to get a user story from the Ideation phase into the hands of the end-user. This value stream has likely been developed over many years, by several groups of people with differing priorities. It is imperative to examine said value stream periodically to ensure it is free of redundancies; and updated to better fit present-day organizational priorities and goals. Deployment Frequency is the easiest metric to collect, because it only needs one table. However, the bucketing for frequency is also one of the trickier elements to calculate.

    Data Extraction And Transformation

    A high MTTR indicates that a team’s incident response is slow or ineffective and any failure could result in a significant service interruption. Companies in virtually any industry can use DORA metrics to measure and improve their software development and delivery performance. A mobile game developer, for example, could use DORA metrics to understand and optimize their response when a game goes offline, minimizing customer dissatisfaction and preserving revenue. A finance company might communicate the positive business impact of DevOps to business stakeholders by translating DORA metrics into dollars saved through increased productivity or decreased downtime. Deployment frequency indicates how often an organization successfully deploys code to production or releases software to end users. DevOps’ goal of continuous development essentially requires that teams achieve multiple daily deployments; the deployment frequency metric provides them a clear picture of where they stand in relation to that goal.

    Over the past years of software development, teams have tried a variety of different metrics with varying success. Many of these tended to be one dimensional – think of just a single axis on a graph – we measure one value and hoped to find some insight about the metric, somehow. Examples of popular metrics over the years have been lines of code, number of bugs fixed, story points completed, or even cyclomatic complexity. In contrast, each of the four DORA metrics encapsulate multiple metrics – essentially creating a three-dimensional view. Communities of Practice must make continuous learning a key priority, and time must be allocated for learning and teaching.

    Organizations must examine time and investment budgets and ensure there are appropriate allocations for learning, experimentation, knowledge sharing and technical debt. If required, monolithic applications must be pared down and eventually replaced with micro-services that are conducive to modern-day technological advances. It is now possible to achieve levels of uptime and resiliency that were unheard of even 5 years ago. Let’s work together to ask questions, celebrate successes and failures alike, and continue to deliver exceptional value to our end users on time, every time. As a proponent of a data-driven decision making culture, I have avoided prescriptive approaches to improving DORA metrics. It is best to contemplate the barriers on a team level, or better still, an application level; and focus on dismantling these barriers in a methodical and purposeful way guided by priority and return on investment.

    Analyzing every one of these is unnecessary, as well as potentially costly. Many projects won’t have to worry about this insight due to their scale. If it emerges that changes to processes are required, these changes must be meticulously recorded, observed and measured as an experiment. The results must be peer reviewed and widely distributed within the organization, so as to foster a culture of experimentation and continuous improvement. Before embarking upon an improvement journey, it is critical to examine where we currently stand. The purpose of this baselining activity is to assess current levels, and to be able to articulate where we’re headed; with real quantitative data.

    As we’ll see in the following lines, the benefits of tracking DORA Metrics go well beyond team borders, and enable Engineering leaders to make a solid case for the business value of DevOps. In this article we will define what DORA Metrics are and how valuable they prove to be, and explain what the groundbreaking research found. Also, we’ll provide industry values for these metrics and show you the tools you have in place to help you measure them. A value stream is the set of actions that take place to add value to a customer from the initial request through realization of value by the customer. Flow load measures the number of flow items in a value stream to identify over- and under-utilization of value streams. Flow velocity measures the number of flow items completed over a period to determine if value is accelerating.

    • 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.
    • Ultimately, this depends on your team’s individual business requirements.
    • Success specifies whether a given deployment was successful.
    • Instead of relying on hunches, and gut feelings, they will be able to visualize their progress, spot roadblocks, and pinpoint what they need to improve.
    • Every DevOps team should strive to align software development with their organization’s business goals.
    • Anytime we start measuring something, it instantly creates incentives – some positive, some negative.
    • I’ve had quite a few debates about when to start measuring lead time for changes.

    When considering a metric tracker, it’s important to make sure it integrates with key software delivery systems including CI/CD, issue tracking and monitoring tools. It should also display metrics clearly in easily digestible formats so teams can quickly extract insights, identify trends and draw conclusions from the data. Flow metrics are a framework for measuring how much value is being delivered by a product value stream and the rate at which it is delivered from start to finish.

    How Long Do Product Changes Take?

    Measuring lead time is important because the shorter the lead time, the more quickly the team can receive feedback and release software improvements. Lead time is calculated by measuring how long it takes to complete each project from start to finish and averaging those times. DevOps teams that leverage modern operational practices outlined by their SRE colleagues report higher operational performance.

    While traditional performance metrics focus on specific processes and tasks, flow metrics measure the end-to-end flow of business and its results. This helps organizations see where obstructions exist in the value stream that are preventing desired outcomes. Metric query parameterDescription of value in responsechange_failure_rateThe number of incidents divided by the number of deployments during the time period. While LTTC and CFR measure the code quality, DF and MTTR are velocity metrics. If they are consistently tracked, and if steps are taken to improve them, together, they can help DevOps leaders boost their team’s performance and bring real business results.

    As they say; you can’t manage what you don’t measure, so we built delivery insights to help you make data driven delivery decisions. Mean time to recover is about measuring the time to recover from an outage. Immediately we can see that MTTR is a tricky metric, in that there is so much variation between the definition of an outage. Did my data center fall into the ocean, or is it just a degraded SQL index? Adding to this, is the nearly infinitely combinations of technologies, architectures, and clouds used across every project. The implementation of this metric has the most amount of customization today.


    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. In Agile, DORA metrics are used to improve the productivity of DevOps teams and the speed and stability of the software delivery process. DORA supports Agile’s goal of delivering customer value faster with fewer impediments by helping identify bottlenecks.

    And be on the lookout for a follow-up post on gathering DORA metrics for applications that are hosted entirely in Google Cloud. 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.

    Once set goals, users will often aspire to achieve these metrics in the easiest way possible – even if that means cheating a little bit. Added to this equation, every project has different architectures, technologies, clouds, processes, SLA targets, etc – there is too much variability to compare different teams, and little to be gained. Baselining your organization’s performance on these metrics is a great way to improve the efficiency and effectiveness of your own operations.

    How Quickly Can We Restore Service?

    The 2019 Accelerate State of DevOps report shows that organizations are stepping-up their game when it comes to DevOps expertise. According to Google, the proportion of elites has almost tripled, making elite performance 20% of all organizations. Waydev’s DORA metrics dashboard enables you to track the 4 metrics across many CI/CD providers In DORA, performers are qualified as Low, Medium, High, and Elite performers.
