• People in general seek rules and structure to make their lives simple and so that when things don't go quite right, they can blame "the system".
• It works out better for managers and founders of companies if people understand a few guiding principles rather than lots of rules. If people understand what you are trying to do and why the principles are in effect, then the appropriate behavior is usually quite clear even with very few rules.
• Unfortunately, most people are not inclined to work as hard as it takes to think through, understand, and internalize even a few principles because it takes effort and critical thinking.

Make it part of the culture to expect people to understand the principles at work, not just the rules. The best way to do this is for the leadership team to model the desired behavior and to explicitly tell people that they are expected to follow suit, and to give feedback when they do and when they don't.
