"For almost ten years, the DORA research initiative has explored the effectiveness and metrics of top-performing organizations driven by technology. This effort has gathered insights from over 36,000 professionals from various sizes of organizations and a wide range of industries. DORA aims to unravel the link between operational practices (capabilities) and their outcomes, focusing on significant achievements both organization-wide and to its members."
"Performance in software development and operations is commonly measured using four key metrics: Change lead time refers to the time taken from a change being asked for until it is successfully running in production. Deployment frequency measures how often new code is deployed to production. Change failure rate looks at the percentage of deployments causing a failure in production. Failed deployment recovery time is how quickly a team can recover from a failed deployment."
"A common strategy to improve all these metrics is to reduce the batch size of changes for an application. By making smaller, more frequent changes, teams can reduce the lead time for changes, increase the frequency of deployments, lower the risk of significant failures, and make recovery from any failures quicker and easier. This approach streamlines the development process and enhances software delivery's overall efficiency and reliability."
DORA research collected insights from over 36,000 professionals across diverse industries and organization sizes over nearly ten years. The initiative connects operational practices and capabilities to measurable outcomes for organizations and members. Software delivery performance is measured by four metrics: change lead time, deployment frequency, change failure rate, and failed deployment recovery time, each defined by time or frequency of changes and failures. Reducing change batch size leads to faster lead times, higher deployment frequency, lower failure risk, and quicker recovery. A culture of continuous improvement enables teams to iterate practices and achieve greater benefits.
