The purpose, values & principles are GREAT and really beautifully haning in the wall. It do not happens in practice.
In fact I had one great manager - doing everything by the book. But when you are challenged to put creativity to work but no budget available you simply can't execute anything.
The culture of collaboration only exist in the wall, in the daily bases, if you are not part of a group you can't force people to work and help you.
political promotion, do not take risks
