Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, what the (a) evidential basis and (b) method of calculation was for his Department's Common Technology Services team establishing the figure of 40 per cent savings from disaggregating large IT contracts; and if he will publish his Department's joint report with McKinsey & Co on that subject.

The figure refers to the estimated annual run cost savings from the delivery of the Cabinet Office Technology Transformation Programme.

The business case supporting this programme estimated 38% savings on the per-user annual run costs for Cabinet Office, compared to the “do minimum” option of retaining the outsourced service provision.

The Government draws on a wide range of advice to ensure we deliver the best possible service for users and value for taxpayers. Details of specific contracts awarded are published regularly on Contracts Finder.
