The document summarizes Tata Consultancy Services' (TCS) changing managerial structure. In 2008, TCS restructured its organization into five new groups: Industry Solutions, Major Markets, New Growth Markets, Strategic Initiatives, and Organizational Infrastructure. This was done to address changes in the external environment like increased competition, boost revenue growth, and improve customer expectations. The restructuring provided opportunities for middle-level employees and helped TCS become the largest Asian IT company serving top global clients.
