This question aligns with Organizational Culture and Leadership , particularly employee engagement and change management. Option D is correct because CPXP emphasizes that true commitment comes from involvement and ownership . When staff are actively engaged in the design and development of a process , they are more likely to understand, support, and sustain the change. This participatory approach builds trust, reduces resistance, and leverages frontline insights. Option C (explaining why) is important but not sufficient alone to secure commitment. Option A (monitoring) and Option B (incentives) may drive compliance but not genuine engagement. CPXP highlights that co-creation and collaboration are essential for lasting cultural change , making staff involvement the most effective strategy for achieving meaningful and sustained commitment.
