In this paper, we will present two examples of how Enterprise Architecture could help make better investment decisions within a multi-country Telecommunications Company (Telco). These two examples relate to two of the significant challenges that a Telco is currently facing:
The invasion of Telco’s traditional playground by new actors, the web players and the consumer electronics manufacturers : Telcos must react and position themselves face to the new entrants
The sharing of IT components between the local companies of the same Telco Group, in order to cut cost through economies of scale
For each of the examples, we will present a strategic view and an engineering view, showing that it is possible to show, on a single A4 sheet, a summary of the technical policy for the delivery of end-user services regarding the two above mentioned challenges.
