Autodesk product designers work together on cross-divisional projects to improve their products across the board. One such effort involved switching the paradigm for presentation of tools from a menu style to a "Ribbon" style, as Microsoft did in 2007. I was the lead designer of the new interface for Autodesk Design Review, an application for viewing and annotating AutoCAD drawings and PDF files. Since this program had the largest number of installations around the world of any Autodesk product, it was especially important to get it right. I used analytics data to drive decisions on the placement and prominence of functions, and usability testing to validate our designs.
