In any large organization, there are basically two classes of rules: 1) stupid red tape rules that slow everyone down and 2) really important rules that you can never break ever. Effective people learn which rules fall into which group so they can break the red tape rules and get more stuff done.
That's a rather binary view and I disagree that rules always fall in either category.
Knowing _why_ a rule exists and what it's trying to prevent/achieve is much more valuable in my opinion. Wether or not to follow or bend a rule depends so much on the context.
