Ten percent of UK IT projects are delivered on time, according to a survey conducted by the Economist Intelligence Unit.
The survey says that the main reasons for project delays are changing business priorities and poor co-ordination between IT and business managers.
Business managers often give poor specifications to IT departments and then insist on changes after the project has been started.
The survey shows that firms that succeed in IT project and service delivery have a big advantage.
The report was sponsored by HP and is based on a survey of 1,125 IT professionals worldwide.
