In recent times, service sector has been the fastest growing sector in the world. While product quality is easier to control with rigorous tests, services are usually produced and consumed at the same time, and service deficiencies cannot be eliminated before delivery due to the personalized and subject nature of services. In addition, service standards are difficult to establish due to subjective measurements, and customers have their own expectations about what service quality is or should be.

For export of services, the usual inquiries from the buyer relate to assurance of continuity of supply and consistency of quality. In addition, services are usually labour intensive, involving complex cross functional integration of several supporting systems.
