The Agile Release Train (ART) is a long-lived team of Agile teams that incrementally develops,

delivers, and often operates one or more solutions in a value stream1. The ART aligns teams to a

common mission using a single Vision and a Program Backlog. The Vision is a description of the

future state of the solution under development. It reflects customer and stakeholder needs, as well

as the features and capabilities planned for the solution2. The Program Backlog is the single source

of truth for the upcoming features of the system. It contains the enablers necessary to build the

Architectural Runway, as well as the user and business features that deliver customer value3. The

Vision and the Program Backlog provide the context and the content for the ART to plan, commit,

develop, and deploy together. Reference: Agile Release Train - Scaled Agile Framework, Vision -
