World’s Largest Business Federation Will Manage Learning and Talent with SumTotal ‘ResultsOnDemand’

Mountain View , Calif. – April 30, 2007 – The U.S. Chamber of Commerce selected SumTotal® Systems, Inc. (NASDAQ: SUMT), a global provider of talent and learning management solutions, to build an online university for approximately 500 Chamber employees across the United States. The online university will be an easily accessible portal for employees to find information related to professional development, tap into best practices and obtain compliance training.

To build its online university, the Washington, D.C.-based organization selected SumTotal’s ResultsOnDemand ™ platform, which is SumTotal’s software-as-a-service (SaaS) model for analyzing employee performance and delivering learning over the Internet

Among the first initiatives for the online university will be delivering instruction aimed at the Chamber’s membership-development team, which focuses, in part, on selling the value of a Chamber membership to small, medium and large businesses.

To supplement training for its membership development team, the Chamber will also use the SumTotal platform to put instruction online so team members can continually refer back to their classes and access the most up-to-date curriculum.
