Abstract
Improving field performance of telecommunication systems is one of the most relevant targets of both telecom suppliers and operators, as an increasing amount of business critical systems worldwide are relying on dependable telecommunication. Finding defects earlier of course should improve field performance in terms of reduced field failure rates and reduced intrinsic downtime. This paper describes an integrated approach to improve early defect detection and thus field reliability of telecommunication switching systems. The assumptions at the start of the projects discussed in this paper are: Wide application of code inspections and thorough module testing must lead to a lower fault detection density in following test phases. At the same time criteria for selecting the right modules for code reviews, code inspections and module test have to be improved in order to optimize efficiency. Experiences from projects of Alcatel Telecom’s Switching System Division are included to show practical impacts.
