I believe I understand what the author of this post is trying to accomplish, but for virtually every "client" I have ever worked for, their eyes would have glazed over by the time they'd read 25% of this response (if they could even get that far). It is worth it to try to help your client understand why seemingly simple changes take a long time to implement. I'd just be surprised if the written response in this post would be of much help to most clients. The face-to-face has a much better shot at being helpful, but, of course, that depends a great deal on the client also.
