Effective Communication Is Not For The Impatient
Recently, I've come to the realization (through example) that effectively communicating complex ideas (even if they are logical and rational) takes much longer than you think. Simply going over a process or procedure in detail and handing over a protocol, then having all of the interested partied look each other in the eye and say "yes, I understand" is not enough.
Even if, at the time, they really DO understand, by the time they go to implement it, they will have forgotten something, or their own biases will prevent them from doing something exactly as it was decided. It's only once they fully make the process part of themselves and take ownership of it, will it stick. This can be a painfully slow process, requiring the same meeting and discussion several times, seemingly going over the exact same details several times in order for it to really take hold.
