It is February and Tim, the Sales Manager at the Mobile Network PotentiallyFinite

(PF), has closed quite a few high value deals with his Advertising clients. But his

teammates, Berners and Lee haven't opened up the bubbly as yet.

Berners is the Partner Manager at PotentiallyFinite and he is responsible for

managing the Network's publishers, who in turn are responsible for supplying the

inventory on which the Network's ads run. Berners has to ensure the supply

requirements of PotentiallyFinite are met to the fullest. At the same time he has to ensure that the publishers he manages gets sufficient revenues such that they are happy and stick on with the Network. If the publishers see their revenue falling then they might shift to a competing network.

Lee is the Operations Manager and she ensures that Demand/Supply Mismatches are kept at a minimal at the same time ensuring that PotentiallyFinite maximizes its revenue given the constraints on the Demand and Supply end.
