The SAFe framework emphasizes the importance of visualizing work to identify bottlenecks in the flow of value. This is aligned with Lean-Agile principles, which advocate for making work visible to help teams understand the current state of the system, identify bottlenecks, and improve flow. By visualizing the flow of all work and tracking the progress of individual items, teams can quickly see where issues are occurring and take steps to address them. This practice is a key responsibility of the Release Train Engineer (RTE), who facilitates Agile Release Train (ART) events and processes, and supports teams in delivering value. The RTE helps manage risks, escalates impediments, and drives relentless improvement, which includes identifying and addressing bottlenecks in the flow of work12.
