Ask 37signals: Do I need a designer to make pretty? - (37signals)

Think of it like paper and pencil. A programmer can use those tools to create a technical diagram of databases and objects. A designer can use those same tools to create a compelling layout with a flow that's just right.

When designers and programmers work with the same materials, they speak the same language. That's an incredibly helpful way to work together (contrast with artists speaking in Photoshop and "HTML cutters" trying to adapt that to the web).

One of the first recommendations that I could give to anyone preparing a project is to get parties with different skillsets involved on a common ground of functionality. Subcommittees and relegation lead to disconnects that you'll expect your product or service to overcome on its own. Instead, take every opportunity to reinforce the unity of the project's team; a flow of information in a common area can usually be more beneficial than more traditional methods. This concept can be applied to the physical way in which your team works as well.
