Ariba LIVE 2007: The Journey Continues to Boca Raton.

Company Paves Road to Spend Management Excellence with a Preview of Final Event in Global Conference Series

SUNNYVALE, Calif. -- Why do thousands of procurement executives and professionals make attending Ariba([R]) LIVE([TM]) events around the globe each year a priority? Because spend management is a journey. And they know that in order to be successful, they need access to fresh insights and best practices that will help them deliver results. On Tuesday, May 1, Ariba, Inc. (NASDAQ: ARBA), the leading spend management solutions provider and host of the global conference series, will offer a preview of the kinds of information provided at Ariba LIVE events, which companies around the world have been leveraging for more than a decade to improve their business and profits. During a live webinar, James Gregson, Senior Manager, Strategic Sourcing, Ariba, will trace the steps of the spend management journey and outline the actions that define success for companies of all types and sizes. The session will take place from 12 p.m. - 1 p.m. ET.

"All companies aspire to improve their current performance and embark on a journey of sorts to make it happen," Gregson said. "Each will take a different path and move at its own speed. But there are common elements that define top performers. Ariba LIVE, and this preview webinar, are designed to provide executives committed to driving organizational change and business excellence through spend management with the tools they need to successfully navigate the journey."

From keynote speeches delivered by executives and spend management practitioners with world-class companies to interactive breakout sessions across six unique tracks, Ariba LIVE events offer practical, actionable information that companies - regardless of where they are in their spend management journey - can use to accelerate their spend management initiatives and the results that they deliver.
