A new government-wide IT strategy could be announced in December.
The programme is expected to be aligned with new Treasury initiatives and will be published alongside the pre-budget report on 9 December.
The strategy sets out the direction for government ICT until 2020, and will include emphasis on cloud computing, open source, and rationalisation of datacentres. There are also plans for a government "app store", encouraging the reuse of business applications across the public sector.
The programme is said to highlight £500m worth of annual savings, which include spending on IT staff decreasing by 5% a year from 2010.
