The global telecommunications industry has changed from a number of co-operating national monopolies oå ering a restricted range of services to a competitive, growing market with players of many types and sizes, oå ering a large range of services. How can vertically integrated incumbents align themselves and their systems to best compete in this environment? Business patterns and enterprise modelling oå er a tool to model a large organization as a number of smaller enterprises that can compete with and co-operate with smaller specialist players in the market.In order to identify enterprises, this paper proposes that there are only a limited number of types of enterprise (manufacturer, service supplier, reseller, agent, broker) and that these enterprise types can only interact in a limited number of ways (component supply, aggregation supply, resell supply, trading, end-supply and commission). With the use of examples, this paper illustrates these types of enterprise and enterprise relationships, and how they can be combined to build both internal and external supply chains, and discusses some of the conclusions that can be drawn from this analysis.
