I was recently on a call with a client and an industry analyst, and the client asked if end user training would be necessary when the new communications technology system was implemented. To my surprise, the analyst said, "No." The theory was essentially that the new system should have a user interface that is easy to use and, like a smart phone, users should be able to figure out how to use it on their own, without training.
While I certainly agree that systems should be easy to use, I think that the smart phone analogy is faulty. Smart phones are an individual tool; they are not necessarily part of an eco-system. Yes, you can install apps that increase interaction with a selected group of your BFFs, but that doesn't make it the equivalent of a corporate communication system.
