Step-by-step explanation:
An Agile Release Train (ART) is a term commonly used in the Agile software development methodology. It refers to a self-organizing, cross-functional team of teams that deliver value in an incremental way. An important aspect of ARTs is that they promote continuous delivery, which means that software can be released at any time, rather than being tied to a fixed release schedule. This helps drive DevOps, which is a set of practices that aim to improve collaboration and communication between development and operations teams, leading to faster and more reliable software releases.
