EDS CEO Ron Rittenmeyer is retiring as Hewlett-Packard integrates the IT services firm it acquired earlier this year.
Rittenmeyer's departure, effective on 31 December, follows thousands of redundancies announced at the two merged firms.
EDS will become a business unit within HP's Technology Solutions Group (TSG).
HP said the new organisational structure will allow the company to sell and deliver more integrated solutions for its customers.
Joe Eazor will assume the role of senior vice-president of EDS, with responsibility for the business unit's operations, reporting directly to Ann Livermore, executive vice-president of TSG.
Rittenmeyer joined EDS in 2005 and was named chairman and CEO in 2007.
Eazor led the EDS deal team through its acquisition by HP and the subsequent integration. Prior to the acquisition, Eazor was executive vice-president of corporate strategy and business development at EDS.
