Optimization of a telecommunications billing system

To remain competitive in a turbulent and rapidly evolving market, telecommunication companies have found it necessary to invest large sums of money on the latest technologies and IT infrastructure. These investments have been a serious drain on the financial resources of these companies who are now seeking ways to pare costs and regain their financial footing. This new reality is increasingly forcing companies to focus on improving processes in order to increase profitability. Process simulation is proving to be a useful tool in helping these companies attain higher levels of efficiency in business critical processes by revealing inefficiencies and redesigning processes. We seek to illustrate the method used to obtain substantial savings in the billing system of Telenor (Norway´s largest telecom company), through the use of simulation.
