Back in the 90's, IBM planned their management courses just like Universities. There were textbooks, and homework. In fact, they were even named similar to Universities.

Management 101 - The basics <-- This was taken in your first year as mgr.
Management 201
Management 301
Management 401
etc etc

When I was there in 1996, there was a full-time team (6 people I think) of trainers.

I have not kept in touch with enough folks to know if that level of training still exists.
