Hewlett-Packard's CIO, Randy Mott, has left the company amid an organisational restructure.
As a result, HP has scrapped the chief administration officer role and plans to extend the role of the CIO.
"As part of the realignment to improve the company's focus on customer-facing businesses, HP will streamline its administrative operations," said HP in a statement.
The statement added: "Randy Mott, executive vice-president and chief information officer, is leaving HP effective immediately. The company will conduct a search for a successor."
Ann Livermore, executive vice-president of HP's enterprise business, has been elected to HP's board. HP said she will continue to act as an interim lead for HP's enterprise services until a replacement is named.
Executives from enterprise servers, storage, networking and technology services will now report directly to Leo Apotheker, HP's CEO.
HP's latest financial results show corporate users are buying its enterprise IT products and services. HP's revenue increased 1% for its second fiscal quarter ended 30 April 2011, compared with the same period the year before.
