The Financial Audit Process Reengineering And The Financial Audit System Development In Telecom Operator

In recent years, the competition among Telecom Operators becomes increasingly fierce simply for the accelerated economic globalization, the rapid development of IT infrastructures, as well as the proper relaxation of telecom regulations. As a consequence, how to reduce the revenue loss in the ordinary business turns to be a hot research topic for most Telecom Operators. However, although the revenue assurance is such of importance, there are few related methods and theories which could give enterprises a general guidance.This paper abstracts and summarizes the practical experiences in a revenue assurance project for a Telecom Operator in some province of China. Theoretically, we present an innovative methodology for data audit, and partition the actual financial revenue data into five classes according to two different abstracted levels. Practically, we reengineer the financial audit process and develop the financial audit system, which could effectively enhance the underline IT infrastructures to accomplish the revenue assurance. Within the period of business modeling, original financial audit process is reengineered based on the theory of BPR, of which we use UML to describe the business process, use the theory of enterprise internal control to detect and optimize the business process. In addition, the switching to the optimized process from the old one is achieved. The reengineering of the financial audit processes accomplishes the modeling of the financial audit business, which is a fundamental step for developing our financial audit system by specifying the correspondent functional requirements. From the perspective of software engineering, the whole life cycle of this system, including the requirement analysis, system designing and implementation, as well as the project management, is also provided in this paper.The reengineering of the financial audit process and the developing of the financial audit system shows that our presented methodology of the revenue assurance could benefit the telecom operators effectively.
