The lack of a benchmark means that we cannot be certain that improvements have been achieved. The Agency told us that they were very pleased with the quality of service being provided and that they were carrying out a review to try and quantify the benefits of the joint venture.

CCTA, the public sector body with the principal overview of public sector deals, told us that it is usually the case in the public sector that outsourcing deals are entered into without a benchmark of pre-outsourcing service levels.
