Sales staff is arrogantly ignorant. They know best, even when they know nothing at all.

Groups implement (or don't implement) policy differently. If the group doesn't like something, they may simply ignore it.
The group level managers' decisions are often overruled by the sales managers. The sales managers will also make decisions for things that affect the groups, but not even tell the group leaders. The groups then have to deal with the consequences of decisions that they had nothing to do with.
The company values are ignored by many, including some in management.
