EDS has revamped its $US310 million service-based contract with the Commonwealth Bank of Australia to deliver desktop and other end-user computing services for the next five years.

The new contract covers all end-user computing services, including desktop, service desk, ATM services, managed output, email, messaging, Outlook Web access and mobile information protection.

The deal follows last year's $US350 million signing of a new master IT&T Agreement involving Enterprise Processing Services (EPS) for mainframe, midrange and data storage until 2012.

EDS A/NZ vice president, Chris Mitchell, said the agreements were in line with a more collaborative and strategic relationship being developed between the two organizations to decouple arrangements and deliver specific business outcomes.

"When we signed the EPS agreement last year we also agreed to a joint charter as a foundation for further enhancing our ongoing business relationship," Mitchell said.

"We support the bank's business every day and the charter reinforces our close involvement in helping it achieve its goals."

Mitchell said the latest contract renewal was a reflection of the hard work that had gone into meeting the quality and service challenges that underpin the relationship.

"The EDS teams continue to work with the Commonwealth Bank to ensure it achieves its strategic vision of excelling in customer service," he said.

"We can help the bank realize this by delivering the most reliable financial services infrastructure in Australia."

Under the new end-user computing services contract, EDS will be responsible for supporting the Bank's 44,000 desktop devices, 3300 ATMs, 4000 printers and 1000 facsimile machines.

CBA group executive CIO, Michael Harte, said the collaborative approach was enabling EDS to find new ways of providing value to the bank through enhancing and meeting end-user expectations.

"EDS has stepped up to the quality and service challenge, adding simplicity, stability and improved delivery to the IT services offered to the bank," he said.

"The latest re-signing is a reflection that EDS has raised the bar and will deliver significantly enhanced business outcomes."

The partnership between EDS and the CBA began in 1997 with a 10-year agreement for IT services.
