CSC has insisted its work on the £11.7 billion Department of Health National Programme for IT (NPfIT) is going "very well", two weeks after ministers were advised by a powerful committee to consider scrapping the programme.

The Public Accounts Committee advised health and Cabinet Office ministers to seriously reconsider the programme, and said it was so disappointed with CSC's work that it was possible the supplier was no longer fit for any government work. CSC has only delivered its main patient records system to three large trusts in nine years, and representatives have been unable to guarantee it would deliver the systems to all trusts by the current 2015 deadline.

"We are performing very well on it," CSC chief executive Mike Laphen told investors in a reference to the programme, as the company reported first-quarter net income up 28 percent to $183 million. "We think we have an outstanding product here."
