This question aligns with Organizational Culture and Leadership , particularly in building sustainable structures for patient engagement. Option D is correct because the first and most critical step is securing leadership and staff buy-in , which ensures organizational support, resources, and alignment with strategic goals. CPXP emphasizes that without internal commitment, initiatives like patient and family advisory councils may lack authority, participation, or sustainability. Establishing buy-in helps define purpose, clarify expectations, and integrate the council into the organization’s culture.

Option C (meeting volunteers) may provide insight but does not establish formal support. CPXP highlights that strong leadership alignment is foundational for successful patient partnership initiatives .
