 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. References: Agile Release Train - Scaled Agile Framework, Vision - Scaled Agile Framework, Program Backlog - Scaled Agile Framework

Reducing the batch sizes of work is critical to improving flow, as it enables faster delivery of value, lower risk, higher quality, and better feedback1. Batch size is the amount of work that moves as a unit through the value stream2. Smaller batches reduce the cycle time, the total time from the beginning to the end of the process to provide value to a customer3. Smaller batches also reduce the variability and uncertainty in the system, leading to less waste and rework2. SAFe provides several practices to reduce the batch sizes of work, such as using User Stories, Features, and Minimum Viable Products (MVPs) as units of work, applying Continuous Integration (CI) and Continuous Delivery (CD) pipelines, and limiting Work in Process (WIP)1. References: Accelerating Flow with SAFe, Make Value Flow without Interruptions, Optimize Flow
