Ariba Helps Growing Enterprises Achieve Spend Management Excellence.

Company to Outline Priorities and Success Strategies During September 25 Webcast

SUNNYVALE, Calif. -- Rising energy and materials costs, increased global competition, and continued customer price pressure is making spend management a priority for all companies. But the imperative is even stronger for growing enterprises that often lack the buying power and resources of their larger peers. On Thursday, September 25, Ariba, Inc. (NASDAQ:ARBA), the leading spend management solutions provider, will host an interactive webcast during which it will outline the challenges of managing spend in today's business climate and strategies that mid-market organizations can employ for overcoming them. The live session, will take place from 2:00 p.m. - 3:00 p.m. ET.

"When it comes to managing spend, growing enterprises face a unique set of challenges," said Paul Tong, Senior Product Marketing Manager, Ariba. "They recognize that procurement can identify opportunities for savings, but often lack the solutions and resources to drive them to the bottom line."

To understand the issues that growing enterprises face in managing their spend, Ariba conducted a survey of executives and procurement professionals at mid-market organizations across a range of industries. The results, published as part of Mid-Market Rising: The Spend Management Imperative for Growing Enterprises (www.ariba.com/resourcelibrary), found that although they place high importance on core procurement activities, growing enterprises generally fall short of their goals because they lack sufficient budget, resources and staffing. Additionally, they lack the tools needed to coordinate information and processes across disparate groups and enforce consistent standard procedures and policies across the organization.

"At Ariba, we are committed to providing mid-market organizations with solutions, processes and knowledge that enable them to manage these issues and achieve their spend management goals," Tong continued. "Through our webinar, participants can gain insight into technology and processes they can leverage to design and execute a holistic approach to procurement that is tightly aligned with business goals that delivers performance improvements and hard-dollar results."
