Final answer:
The flow of Portfolio Epics is usually managed using Kanban boards, which are a visual tool in Agile and Lean practices to visualize and limit work in progress, ensuring high-priority items are addressed timely.
Step-by-step explanation:
The flow of Portfolio Epics is typically managed using a) Kanban boards. Kanban boards are visual tools that help manage work as it progresses through a process. They allow teams to visualize the flow of work and are particularly useful in Agile and Lean practices, such as in the Scaled Agile Framework (SAFe). The Kanban approach to managing epics involves visualizing the work on the board, limiting work in progress, and managing the flow to ensure that the highest priority items are being worked on at the right time. This is in contrast to other methods like Scrum methodology, which focuses on time-boxed iterations or sprints, Gantt charts which are used for traditional project scheduling, or Critical path analysis which is used to identify the longest stretch of dependent activities and the time necessary to complete a project.
