More and more multinational companies are turning to offshore outsourcing to help them cut costs and free talent to come up with new products and services. In recent years, Procter & Gamble, DuPont, Cisco, Unilever, ABN Amro, and Marriott have all signed megadeals with global outsourcing companies to overhaul internal operations such as accounting or human resources or to upgrade their technology.
