It Didn't Happen

It didn’t happen unless you wrote it down.

What you heard may not be what they thought they said. And what you thought you said may not be what they heard. You always need to write it down and share it.

Especially when you are talking to a customer. Because the odds are good that what you deliver will not be what the customer thought they were going to get.
