From the official site :

There's a flurry of creative energy up on the third floor of Skywalker Ranch's Main House. That's where the Art Department brainstorms and generates fantastic pieces of concept art to clarify George Lucas' visions of a galaxy far, far away. For every piece that passes through the approval gauntlet, a dozen or so are rejected. When it comes to organizing the outcome of this process -- the many sketches, paintings, digital files, sculptures and models -- the Art Department relies on coordinator Fay David.

"I'm fascinated by the whole process of creating these creatures and new worlds," says David. "It's such a treat for me, every day, to come to work and see what the concept artists are designing. Now that I'm working with the David Dozoretz and the Animatics Department, I get to see them take that artwork and bring it to life. I'm continually blown away every time I see the work of the Animatics crew."

David, who began her career at Lucasfilm as a Production Assistant at Industrial Light & Magic during Episode I, came to the Art Department early in Episode II's pre-production. The task of developing an electronic method of tracking all the Art Department's assets throughout production fell to Lucasfilm's IT Department, with David's input.

Boba_Phat also finds confirmation on some rumors in this article:

"... Another important role that David plays is keeping track of the myriad of strange names for aliens, creatures, devices, and vehicles that evolve throughout production. It's her notes that keep track that Twi'leks are from Ryloth, that Po Nudo is a senator from Ando, that Senator Tessek's name is now Tikkes, and which characters are allied with the Corporate Alliance, or the Techno Union, or the Commerce Guild."
