An agile workflow and CI/CD are related, however, they are not the same! They describe completely different aspects of the software development pipeline. Agile development, refers to the process or methodologies for managing workflows, meeting cadences, and team organization in software development. An agile methodology embraces change while accelerating delivery by listening and responding to customer needs and involving them in each stage of the development process.
CI/CD relies on automation to remove the human elements that create bottlenecks in releasing and improving the software. In both CI and CD testing is automated throughout the pipeline and is done frequently to minimize the costs and time it takes to remediate defects.
