Build a stakeholder map and communications plan for the [Program_Name] process improvement initiative spanning [Business_Units] and key [Customer_Segments]. Classify stakeholders by power/interest and advocacy/resistance; identify change sponsors [Change_Sponsors] and credible messengers at depot/terminal level. Surface likely objections (service risk, cost-to-serve, driver productivity) and define targeted interventions. Output format requirements: (1) Stakeholder Register table [Name, Role, Site, Power, Interest, Stance, Key Concerns, Influence Levers, Action, Owner]; (2) Power–Interest grid with color-coded stance; (3) Message Matrix [Audience, Core Message, Proof Points, Call-to-Action]; (4) Communications Calendar covering [Timeframe] [Channel, Frequency, Senders, Materials]; (5) Engagement Risk Log with mitigation and monitoring KPIs (reach, open rate, attendance, sentiment). Provide a concise brief for executive sponsors with three talking points tailored to top customers and unions. Include measurement plans to pivot if sentiment deteriorates.
