The stakeholder engagement strategy is designed to involve stakeholders who have the power to affect success, either positively or negatively. ACMP explains this includes executives, managers, employees, and informal influencers. Stakeholder analysis (B) identifies them, but the engagement strategy (A) ensures they are involved in meaningful ways to support adoption. Sponsorship engagement (C) is specific to leaders, while communications engagement (D) covers messaging but not active participation.
