Assess learners' ability to design a comprehensive, evidence-based, scalable workplace physical activity and health-promotion program that integrates behavior-change theory (e.g., SCT, COM-B, TTM), wearable-device data monitoring, periodic biometric screening, culturally adaptive strategies for diverse employee populations, and a mixed-methods ROI evaluation plan. Task must define objectives, target populations, implementation steps, data governance and analytics approaches, engagement and incentive mechanisms, scalability considerations, outcome and cost-benefit metrics, and an implementation timeline with evaluation milestones.
