Like CRM and a host of other TLA's (three letter Abreviations), when discussing PRM we need a clear definition as it can cover a multitude of sins. From Content Providers to Handset Retailers, Telco Operators today need to deal with various other parties in supplying services through the value chain.
Why are these 'Partners' increasingly important is because they frequently control end-points of the value chain where services are created or consumed (bought). So that Operators are not relegated to simply supplying the Pipe the value chain needs to be integrated not only Technicaly but also from a Business Flow and intelligence perspective. This is where the difficulty occurs as the Partners frequently have differing objectives and the sharing of information although potentialy providing a better service to the consumer is not always seen as generating the most profit for each member of the value chain.
Control of the value chain, 'ownership' of the consumer and how to maximise the benefits (cost and profit) to all members of the value chain (including the consumer) are the critical issues.
