This 2018 update of the HM Treasury’s Green Book is essential reading for local authorities, and other relevant place-stakeholders, applying for funding. It focuses on how to appraise and evaluate policies, programmes, and projects - with appraisal referring to the assessment of costs, benefits, and risks to alternative ways of meeting objectives; and evaluation involving a systematic assessment of an intervention’s design, implementation and outcomes. The document explains how appraisal and evaluation are key parts of The Policy Cycle, which includes: Rationale; Objectives; Appraisal; Monitoring; Evaluation; and Feedback. Used alongside complementary resources, such as the Aqua Book, Magenta Book, and Managing Public Money Guide, it helps with the development of transparent, objective, evidence-based appraisal and evaluation of proposals to inform decision making and business cases. The guide, designed to be accessible for those with or without technical knowledge in this area, covers the following: appraisal and government decision-making; how to generate options and long-list appraisals; how to undertake cost-benefit analysis of short-lists; presenting appraisal results; and evaluation.
