DIUS was created by machinery of government changes in July 2007 from elements of the then Department of Trade and Industry and Department for Education and Skills.
As a consequence the Department has not yet existed for the specified periods of 12 and 24 months. At this point staff turnover has not been analysed by the new Department as the systems are not yet in place to do so reliably. The Department is undertaking a project to move to a shared services HR Data platform, and, as soon as this project is completed, will be in a position to analyse and provide such data. Until such time, the collection of the required data would involve disproportionate cost.
