The reviews aim to improve the capability of the civil service to meet today's delivery challenges and to be ready for tomorrows.
Sir Gus said: 'We are well underway with the Capability Review programme now. Twelve departments have been or are presently undergoing Capability Reviews, showing how we remain on track with our determination to develop a world class civil service for the 21st century.
'We recently published the findings of the first four department reviews. As well as recognising the areas where departments do well these reviews demonstrated how we are prepared to both highlight areas of improvement and put in place tough actions to achieve these improvements.'
The review teams have been drawn from the private sector, the wider public sector and board-level members of other government departments.
The findings of the Capability Reviews for these five departments will be published in spring 2007.
