Abstract
This paper describes he process used to adapt Software Reliability Engineering (SRE) to a GUI-based ne work management system. This system is used for the operations and maintenance of GSM mobile elephone networks. The objectives were to formally quantify customer usage of the software in he field, to increase test effectiveness, and to establish an accurate pre-release software quality indicator. It reports on a novel use of capture and playback tools to automatically generate operational profiles on a GUI system, and on the process model developed to adapt and implement SRE. I also describes the application, with minimal overhead, of the operational profiles to the existing test process and practical lessons learned as a result of this experience. Initial results show that it is no necessary to wait until the end of the SRE implementation process to see benefits. This paper demonstrates that significant test effectiveness improvements can be seen during the implementation of SRE.
