Government departments still have few incentives to commission and carry out high-quality evaluations of major projects. High quality evaluation is an important means of providing evidence about what works, transparency about what value a project has produced, and making the case (or not) for further investment. As we pointed out in our May 2022 report on the use of evaluation and modelling in government, in 2019, only 8% of £432 billion of spend on major projects had robust impact evaluation plans in place, and 64% of spend had no evaluation arrangements at all. The Evaluation Task Force is currently updating the 2019 analysis of how much evaluation of major projects now takes place and there is still room for improvement. In our May 2022 report we also pointed out that the same barriers such as a lack of political engagement and a lack of incentives for departments to produce evaluations had persisted since 2013. HM Treasury says it still has more to do to address these barriers, but that the time that it can take for value and benefits to be realised and the time it takes to carry out an evaluation can be barriers. HM Treasury does not, however, consider the cost of evaluation to be a barrier. Recommendation 2: HM Treasury and the evaluation task force should develop a plan that addresses the root causes of why evaluations are not routinely carried out and how to incentivise departments to carry our more high-quality and independent evaluations.
