The Civil Service today signed a new technology contract with computer giant Microsoft in a deal it says will save taxpayers £2 million.
The NICS will pay £2 million to use Microsoft operating systems and products for the next three years, but the government claims the agreement will generate the same amount in savings.
The contract renews a deal first signed three years ago.
The technology will be used in the Civil Service's Shared Service Organisation IT project.
The agreement was signed at Clare House in Belfast.
NICS Shared Services Organisation Director Paul Wickens said: "This renewal agreement with Microsoft will result in around £2 million savings for the NICS over the next three years.
"This agreement not only builds on the strategic relationship that the NICS has with Microsoft but, in the current economic climate, represents real value for money for the NICS."
Klaus Holse Anderson, Corporate Area Vice President of Microsoft Western Europe added: "We are now in a position to assist the NICS to enhance their Shared Service, and help to deliver even better citizen services to NICS customers across Northern Ireland.
"We will also focus on contributing to the NICS objectives to reduce costs and increase efficiencies, by enabling better collaboration and streamlining of associated business processes through the provision of key enabling technologies and solutions."
