The age old question is should you adhere to Rules or adhere to Principles? The answer of course is total adherence to Principles. Rules are only a methodology to accomplish those Principles. What is the story being told by your Rules and how is that different for the story of your Principles? Now has everyone in your organization an understanding about the strategic clarity of those Principles? If they are not, they will seek cover under the umbrella of Rules to the detriment of your customers.
Principles > Rules.
