When trust or satisfaction is an issue with a stakeholder-especially one as critical as the sponsor-the first step is direct communication. A one-on-one meeting to understand expectations, concerns, and establish rapport is essential. This aligns with stakeholder engagement best practices, where early and proactive engagement is prioritized. The PMBOK Guide - Seventh Edition, in the Stakeholder Performance Domain, recommends identifying and analyzing stakeholder needs and initiating communication to build or maintain relationships. Option A is too process-oriented and premature before establishing rapport. Option B is informative but lacks interpersonal connection. Option C provides updates but does not address dissatisfaction or rebuild trust.
