Elite Model Management! It launched the careers of the above-mentioned models and now it has launched an OBA to improve the way it works.  

Elite Model Management represents hundreds of models to worldwide designers, beauty product firms, magazines, and movie studios. The company’s bottom line depends on scouts, booking agents, and executive management working behind the scenes. After experiencing poor adoption of its industry standard booking software, Elite decided to bring its applications together using Windows Vista™, the 2007 Microsoft Office system, and Microsoft Exchange Server 2007. The result is an Office Business Application that consolidates applications and allows people to quickly find and act on information, coordinate day-to-day activities, and keep track of important billing processes.
