Whenever you present a product to your client–whether it’s a series of mock-ups, an intermediate-stage product, or a finished map–be proactive by letting the client know what decisions were made and why those decisions were made with reference to the design. You want to essentially “announce” what you’ve done. There are two reasons for this:
(1) To thwart questions and negative comments. When the client understands upfront the rational basis for color choices, font choices, and overall design choices, they are more likely to agree with what you’ve done.
(2) Really good design is easy to ignore. People do like to say that no feedback is good feedback, but you want to get credit for those good decisions. Go ahead and explain how the map was made and your client will have a whole new understanding of your capabilities.
Remember, a great map (or any project for that matter) will come from one of three situations: a receptive client, a noble cause, or great subject matter. Seek these.
