Chunghwa Telecom Co., Ltd. (CHT), a leading telecommunications company in Taiwan, was facing challenges with its existing billing system. The company, which provides services in fixed line, mobile communications, and data communications, has a subscriber base of 23 million. The billing system, based on an IBM mainframe, tracks billing for calls, collates monthly statistics relating to telephone charges, bill consolidation, bill delivery, clearing, bill collection, suspension, resumption and the stopping of phone services, refunds, arrears tracking and bad debt management. With an annual bill turnover of about NT$180 billion, it is Taiwan’s largest telecommunications billing system. However, the increasing competition in the industry and the launch of many new businesses and services, including ADSL, home broadband and MOD businesses and related services, were putting a strain on the billing system. The company needed to enhance its billing system to meet the growing needs of its value-added business development services.

To enhance its billing system, CHT decided to use Compuware’s application system quality solution, Xpediter, its file management solution, File-AID, and application system efficiency management solution, Strobe. These tools have been used by CHT for about 18 years and have become an integral part of their daily work. With Xpediter, CHT’s programmers can track each and every step of the program implementation process, enabling them to detect any problems quickly, thereby significantly reducing testing and debugging times. File-AID is a collection of data management tools that provide simple and quick access to different forms of information, for example, rapid access to VSAM, DB2 and IMS data files. Strobe enables administrators to evaluate and analyze the application performance of the IBM z/OS mainframe, locate bottlenecks that might be affecting an application’s efficiency and optimize the productivity of the batch processing application in the accounting system.
