It does not mean that all the developers understand all the design, but at least now they can see what the important elements are. As I started to write this article I was overwhelmed by the things I could talk about. Lots of anecdotes and tips came to mind.

That selection of information is one of the most important parts of communication, and it is the responsibility of every designer.
