Explanation
The Portfolio Kanban system is a method to visualize and manage the flow of portfolio Epics, from ideation through analysis, implementation, and completion1. The analyzing step of the Portfolio Kanban system involves developing a Lean business case for the Epic and presenting it to Lean Portfolio Management (LPM) for approval1. If the Epic receives a 'go' decision from LPM, it will be moved to the ready state in the Portfolio Kanban, where it will wait until one or more Agile Release Trains (ARTs) have the capacity to implement it1. The other options are incorrect because:
A: The Epic Owner does not have the authority to approve the Lean business case. Only LPM can make the final decision on whether to proceed with the Epic or not1.
C: The Epic will not remain in the analyzing step after receiving a 'go' decision from LPM. It will be moved to the ready state, where it will be prioritized using weighted shortest job first (WSJF) and other factors1.
D: The Epic will not be implemented based on its WSJF ranking alone. It will also depend on the availability and alignment of the ARTs that can deliver the Epic1. References: 1: Portfolio Kanban - Scaled Agile Framework
