Microsoft's HR mission is to create an empowering environment for employees through a focus on culture, talent, leadership, and management. HR aims to build a modern corporate culture through increased productivity via a self-service portal, providing employees with new skills through learning programs, and modernizing communications to reach all workers. Microsoft uses tools like SharePoint, Learning Central, and Yammer to achieve these goals and help unlock HR's potential to contribute more strategically to business performance through workforce analytics and insights.
