• Develop and execute comprehensive communication strategies that create compelling change narratives connecting transformation to business outcomes and employee experience
• Conduct change impact assessments, facilitate pilot programs, and implement tiered rollouts to minimize change fatigue and maximize adoption
• Define and track success metrics (adoption rates, sentiment, business impact) and provide data-driven insights to leadership on transformation progress
• Lead change management for the integration of AI-powered HR solutions (e.g., predictive analytics, intelligent automation) into the employee experience
• Serve as trusted advisor to HR Leadership on change management best practices, facilitating stakeholder alignment and decision-making
