Deployment frequency is a metric that measures how often software is deployed to a production environment. It is used to measure the efficiency of the deployment process and to identify areas where the process could be improved.
The formula for Deployment Frequency is:
Deployment Frequency = (Number of Deployments / Time Period)
It is calculated by measuring the number of times the software is deployed to a production environment over a specific period of time, such as a week or a month, and dividing that by the length of the time period. The unit of deployment frequency is typically in deployments per day, per week, or per month.
For example, if software is deployed to production 5 times in a month, the deployment frequency would be 5/30 = 0.16 deployments per day.
It’s important to track the Deployment Frequency over time, compare it against industry benchmarks, and track it by different segments, such as by different teams, products, or customers, in order to identify where the problem is and take action to increase the Deployment Frequency.
Deployment frequency is an important metric for companies that practice continuous delivery and DevOps, as it allows them to identify trends in efficiency, and to make informed decisions about process improvement and resource allocation.
It’s also important to keep in mind that the deployment frequency should be aligned with the business requirements and the needs of the end-users, deploying too frequently can cause instability and too infrequently can cause delays in delivering new features and bug fixes.
