BT has signed a multi-million pound contract with Oracle, for the technology giant's human capital management (HCM) software suite.
The exact financial terms were not disclosed.
BT will adopt Oracle HCM cloud globally, affecting all 87,900 employees. The telecoms giant said that the software will help underpin the company's growth plans and help to support its overall business strategy.
The software will be used throughout the company's management process from recruiting and managing staff, to identifying future workforce needs using analytics.
BT said that replacing its existing systems with Oracle's HCM cloud will help to improve its service delivery and be an easier-to-use HR suite for employees.
The telecoms giant added that a key benefit of the software was that all users would have access to the same user interface, which will improve compatibility and ease HR administration.
"To underpin our growth agenda and support delivery of our business strategy we are looking closely at all aspects of how we manage our organisation. Transforming the role of HR in the business and the way in which we manage our people is key to this success," said Clare Chapman, BT's group people director.
"We are excited to work with Oracle as the software product suite provides us with the breadth, depth and quality our ambitions require," she added.
Former HP chief, and now Oracle President, Mark Hurd, said that Oracle was "delighted" that BT had selected the firm's HCM cloud offering.
"People are at the centre of every successful organisation. BT is transforming the way it manages its workforce to help drive growth," he said.
