Question to the Department for Work and Pensions:

To ask the Secretary of State for Work and Pensions, pursuant to the Answer of 8 July 2014, Official Report, column 278W, on personal independence payments, what his Department's definition is of a mature system; and how he proposes that the maturity of the system will be measured.

The publication of any new statistics series needs to ensure that it is based on robust data and the measures reflect the system that is being delivered and latest performance. The Department’s statisticians are currently looking at developing measures around clearance times and will pre-announce future publication in line with the UK Statistics Authority protocols.
