There are too few evaluations of government’s major projects. 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. HM Treasury told us that this figure is too low and that it is not acceptable for departments to have no evaluation arrangements in place. The IPA told us that most departments have gaps in terms of their evaluations but that the Ministry of Defence has particularly significant gaps. The Evaluation Task Force is currently updating the 2019 analysis of how many projects in the Government Major Projects Portfolio have robust evaluation plans.9
