Communiqués -- Juillet (mois) 31, 2007

EL SEGUNDO, Calif., July 31 -- Computer Sciences Corporation (NYSE: CSC) announced today that it has earned SAP Customer Competence Center (CCC) recertification for its work on the U.S. Army’s Logistics Modernization Program (LMP). CCC certification signifies that an organization has met SAP standards for its practices, procedures and performance. Less than four percent of worldwide SAP implementations and fewer than one percent of SAP clients in North America have been awarded the certification, according to industry figures. CCC certification requires reevaluation every two years to ensure sustained quality and commitment to applying industry best practices.

CSC’s LMP team earned its initial certification in April 2005 and was the first CSC organization in North America to receive the award. The Army’s LMP is one of the world’s largest enterprise resource planning implementations and is completely modernizing the Army’s supply chain management operations. CSC provides end-to-end application development and support services to the LMP.

“Our recertification as an SAP Customer Competence Center reflects CSC’s dedication to providing world-class support to the Logistics Modernization Program,” said Austin Yerks, president of CSC’s Defense Division. “This award also honors the experience, expertise, and collaborative efforts of the CSC team members who deliver significant business results to our customers.”

SAP CCC certification is granted to organizations that exceed benchmarks for adopting effective business processes, and for maintaining and promoting technological expertise. The award affirms CSC’s commitment to achieving the highest standards in business and technology performance, which translates into greater productivity gains for its customers.

An audit by SAP’s Operations Competence Assessment organization analyzed how CSC’s LMP team managed the SAP environment, including the business processes and technology tools used to support the LMP production system. The results were then benchmarked against industry best-practice standards.

SAP CCC recertification serves as an independent review of business processes and technological efficiency, validating the framework CSC has in place to ensure continued high levels of performance in both service delivery and service support to the LMP.
