What is one way Kanbans are used in SAFe?

Kanbans are an integral part of the Lean-Agile framework utilized in SAFe, primarily focusing on visualizing and managing the flow of work. The primary use of Kanbans in SAFe is to help teams manage workflow and optimize processes by limiting the amount of work in progress, which subsequently aids in managing queue length effectively.

By using Kanbans, teams can visualize their work items through various stages in a workflow, thereby providing insight into the current status and helping to identify bottlenecks or areas that need improvement. This approach enhances transparency and efficiency, ensuring that teams can maintain a steady flow of work and avoid overloading any part of the process.

While managing nonfunctional requirements, PI objectives, and sprint planning are all important components of Agile and SAFe practices, they do not directly correlate with the specific role of Kanbans, which is primarily concerned with visualizing and controlling the flow of work items through a process. This focus on flow and queue management is what distinguishes the correct choice.
