I had a conversation with a co-worker about this very thing on Wednesday.  I made a couple of suggestions based on what seemed to work at my former place of employment and he told me I just didn't understand the culture of my current organization.  Which apparently said change is very hard to come by here.  This from a person in a position who could effect change.  So with an attitude like that, I will no longer offer any suggestions, which is an attitude unfortunately that stifles any further chance of change.
