Information architecture – the black ship?

As I already wrote my employer form several teams to deal with architecture. While we had tremendous progress in the infrastructure, business and system architecture teams we seem to go very slow with the information team. At first sight I was sure that it won’t be any trouble to deal with information architecture but as the time pass is became more and more difficult to deal with.

First of all the level of abstraction is pretty high, which is not helping us at all. Then the amount of data regarding Information architecture is pretty low. Especially when you are looking for models for organize information by types of users, types of information (core vs. administrative ) and map those classifications into systems. I get the feeling that as much as infrastructure architecture is the most develop one, Information architecture is the black ship in that family.
