Abstract

The Enterprise Modelling (EM) approach to systems design can promote systems integration and data integrity. This results in greater business efficiency and improved customer service. This paper reports on a comprehensive case study of Telstra, which is Australia’s leading telecommunications carrier. Specifically, it reports on Service Level Agreement and reporting performance of two similar systems evaluated in terms of accepted Information Systems Architectural Criteria. One system named Mobile Number Portability (MNP) was designed using the latest object-oriented tools. The other named Data Repository System (DRS) was designed using the EM approach. DRS significantly outperformed MNP confirming the claims made for the EM approach.
