DevOps is an important competency for a disciplined agile team.

DevOpsis a key competency in Disciplined Agile, aiming to create a smooth flow of work from development through to operations. This involves practices such as continuous integration, continuous delivery, and automated deployment, which help to reduce cycle time, improve feedback loops, and ensure the product is always in a deployable state. The focus is on integrating development and operations to deliver value to customers more rapidly and reliably.

Options B (using developers for operations), C (automating testing), and D (involving operational teams in development) are components of DevOps practices, but the primary goal is to establish a seamless workflow.
