HM Treasury has used the last two spending reviews to increase the emphasis on evaluation in departments, but acknowledges it has a lot more to do to address the persistent problems which prevent the provision and use of evaluation.17 Working with the Evaluation Task Force, HM Treasury asked departments to provide evaluation evidence for each line of capital budget spend, and for each new line of resource budget spend.18 All of this is a welcome step forward, but we are disappointed that HM Treasury did not make use of its powers earlier, despite the NAO recommending it in 2013.19
