1. Include the words "always" and "never" in your architectural principles and policies
2. Believe positional authority trumps ability to influence
3. Practice methodology without anthropology
4. Hire an innovator and proceed to micromanage him/her
5. Utilize crowd wisdom for decision making rather than intelligence collection
6. View your architecture as an end, rather than a means










Excellent points Brenda.
Here are a couple of additional ones to consider:
7) Equating your enterprise architecture with your technological implementation/infrastructure
8) Assuming that what is policy today is sacred and cannot be changed
9) Expecting efficiencies to emerge rather than business innovation opportunities
