What is the purpose of the portfolio Kanban system?

• A. It monitors the release calendar
• B. It tracks epics across the portfolio
• C. It logs defects
• D. It manages the flow of epics

Answer: (D)

The portfolio Kanban is about visualizing and controlling the flow of epics as they move from idea to delivery across the portfolio. It provides stages and gates for epics—funneling, analyzing, approving, and moving into the portfolio backlog and then implementation—so decisions about funding and sequencing happen at the right points. By limiting work in progress and focusing on the flow, it helps ensure that the most valuable epics are analyzed and funded, and that delivery remains aligned with strategy.

This system isn’t specifically for monitoring a release calendar or logging defects; those are handled at other levels or with different tools. The key purpose here is to manage the movement and prioritization of epics through the portfolio pipeline.
