Deltek Receives 2008 ACE Award for Achievement in Customer Excellence

Deltek recognized by CustomerSat as an outstanding organization for customer support satisfaction

Herndon, VA, December 18, 2008 – Deltek, Inc. (NASDAQ: PROJ), the leading provider of enterprise applications software for project-focused organizations, today announced that it has received the 2008 Achievement in Customer Excellence (ACE) Award for “Customer Support Satisfaction.” The program’s sponsor, CustomerSat, recognized 27 recipients this year.

Since 2005, the annual ACE Awards have recognized CustomerSat clients who demonstrate rigorous application of customer feedback processes and outstanding performance that result in exceptional customer satisfaction. ACE Awards validate an organization’s success and effectiveness in delighting customers and building loyalty, as well as those individuals responsible for serving customers.

"Customer satisfaction is much more than a key performance metric," said John Chisholm, executive vice president of MarketTools and general manager of CustomerSat. "It is the most enduring and consistent predictor of customer loyalty, long-term growth and corporate value. Moreover, it is the measure that customers themselves care about most. The CustomerSat ACE Awards recognize organizations that have both committed to and achieved the highest levels of customer satisfaction."

ACE Award Selection Criteria
Qualifying performance is a combination of customer satisfaction mean scores and top-box rating percentages maintained during the year. CustomerSat ensures that the survey processes on which metrics are based are rigorous, defensible and repeatable. Surveys may use either a census of customers or representative sampling with specified minimum confidence levels and maximum margins of error.
