Scaled Agile Framework (SAFe) Release Train Engineer Practice Test

Which statement describes flow velocity?

1. The system throughput

2. The amount of Architectural Runway items in the backlog

3. The number of Features committed to during PL Planning

4. The number of Story points the combined ART plans for within each Iteration

The correct answer is: The system throughput

Flow velocity refers to the measure of how much work is being completed in a given timeframe, closely related to the system's throughput. It essentially captures the rate at which value is delivered to customers by the Agile Release Train (ART). In this context, throughput reflects the total amount of completed work items, such as user stories or features, and is a critical metric for assessing the efficiency and productivity of a development process. While considering the other options, the amount of Architectural Runway items in the backlog focuses on the foundational elements that enable new features but does not measure the speed or capacity of delivering completed work. The number of features committed to during PI Planning indicates planning activity rather than actual delivery performance. Lastly, the number of story points planned for each Iteration provides insight into the scope of work intended but doesn't directly equate to the velocity achieved, which is based on completed story points rather than planned ones. Hence, flow velocity directly correlates to the system's throughput, making it the most accurate choice.
