What not to do during deployment

At the aQuatic conference this week, we started talking about a number of mistakes we had made in rolling out our acro* implementations. Please share them here...

For example, at Symantec, we initially underestimated the complexity of the rollout. Also, we started with rules and then did terminology, and in retrospect I probably would have focused on terminology first.

What would you have done differently?

Thanks,
