Tough to make generalizations, but I can imagine the chaos if one didn't obey the rules. Having said that I get very frustrated when the reply to the question "why do we do this this way?" is "because of the rules".
I try to live my professional life, the best I can, by the advice I got from one of my first supervisors "rules are made to be changed". Early on in my career I learned that if you wanted to change the rules, a simple request was NOT going to get it done and that you had better be willing to not only explain/justify the change but be willing to pay a "price", in some cases, if the request was disapproved.
Been a rather long time since I was employed by anything other than a federal government organization BUT my contacts with people in the private sector, and my memory tend to indicate that the government has NO corner on this issue
