Satyam Computer Services Ltd. Fuels Global Knowledge-Sharing Initiative with SumTotal Enterprise Suite.

MOUNTAIN VIEW, Calif. -- SumTotal(TM) Systems (Nasdaq:SUMT), and its partner C&S signed a contract with Satyam Computer Services Ltd. -- a leading global consulting and IT services company -- to make SumTotal Enterprise Suite the backbone for the Satyam Learning Center (SLC). SLC delivers nearly two million hours of education each year to 28,000 IT professionals in 55 countries.

C&S is a joint venture between Computer Associates and Satyam Computer Services. C&S has a strategic partnership with SumTotal to resell and implement the SumTotal Enterprise Suite.

Satyam has identified knowledge management as an organization-wide initiative to bridge the information and knowledge gaps among Satyam's global associates.

Also, to keep pace with the opportunities in its industry, Satyam has realized the importance of providing support services in a virtual manner to its customer-facing units. To achieve this goal, Satyam has "virtualized" an array of administrative, financial and HR processes through an organization-wide portal named "eSupport."

The company sees SumTotal's software solution as a key enterprise application to enable these two enterprise-wide initiatives. This will enable associates to focus on what is critical: serving customers by addressing their needs in a proactive manner.

Satyam will be implementing SumTotal's solution across all of the global consulting and IT services firm's locations.

"SumTotal Enterprise Suite gives us superior capabilities to deploy and administer these new learning initiatives with much more scalability and flexibility," said Ed Cohen, senior vice president of Satyam Computer Services Ltd. "The solution also provides the ability to set up and run various domains, courses and audiences for a globally distributed organization, such as ours, with operations across six continents."

"We believe that SumTotal's solutions will align our knowledge-sharing programs and spending with corporate initiatives for future growth," added Cohen.

"We feel that Indian organizations in the financial services, telecommunications, retail, IT services and ITES sectors, who are expanding rapidly, will be able to differentiate themselves from the competition by investing in SumTotal's solutions to improve employee productivity," said Sudheer Koneru, managing director, India, SumTotal Systems, Inc. "As a global leader in this marketplace, SumTotal stands committed to bringing the best of breed talent and business performance management solutions to India to cater to the need of Indian organizations."
