Because you're reading this - you probably already know all about P2P. But do you really know what P2P is? Because depending on whether you see it from a finance point of view or a purchasing point of view you could have a very distorted view of what getting P2P right is all about. It's a bit like a police investigation. Three different witnesses to a crime can give three entirely different accounts of an incident - so much so that the police could be forgiven for thinking that there was three separate incidents. The witnesses are not stupid and they're not lying - they simply have different points of view. And its the same with P2P.
