@donasmrs-- Compared to some of the other more classic organizational culture models, adhocracy is a newer model.
As far as I know, some of the big computer software and web companies have this type of organizational culture model. That's why they're not only very successful, but also some of the most desirable places to work.
These organizations care less about hierarchy and more about team work and creativity. I think that this is the new age organizational culture model.
