With more than 20 years of software industry experience, much of it focused on mission-critical decision support software development, Thorpe joined ILOG in 1999. In her previous role as director of business rules product marketing, Thorpe led the product strategy that contributed to rapid market adoption for ILOG's business rule products into the finance, insurance and supply chain industries. Under Thorpe's leadership, ILOG business rule product revenues have grown more than 100 percent year over year, and the company has become widely recognized as a business rules market leader and innovator. This distinction was punctuated with recent industry accolades including the Software Development Magazine Productivity and Crossroads A-List awards. With this promotion, Thorpe will now have product marketing responsibility not only for ILOG's business rules products, but also for the company's visualization and optimization product lines.
