North America is the world's largest outsourcing market. All levels of government are feeling budgetary pressures. That's paving the way for increased private sector involvement in the delivery of public services. Our work here focuses on two primary service areas - IT & Professional Services and Managed Services. Our IT & Professional Services practice designs, develops and deploys IT solutions that enhance the quality and accuracy of information and provides seamless information-sharing. Our Managed Services practice delivers mission-critical operations that increase efficiency, productivity and quality of service while enabling the customer to take on higher priority assignments.
