Which statement describes flow velocity?

Flow velocity in the context of SAFe is defined as the number of backlog items completed in a given time. It is a measure of the system’s throughput, which reflects how efficiently the Agile Release Train (ART) delivers value. This metric helps teams and organizations gauge their productivity and predictability over time. By tracking flow velocity, ARTs can assess their performance in delivering features, enhancements, and fixes, and make informed decisions to improve their processes and delivery cadence1.
