This guide, from H M Treasury, is the central guidance for all UK government departments on evaluation.
It focuses on: how evaluations should be designed and managed; outlining some of the different evaluation options available; how evaluation improves policy making; how evaluation results and evidence should be interpreted and presented; and how thinking about evaluation before and during the policy design phase can help to improve the quality of evaluation results.
"All policies, programmes and projects should be subject to comprehensive but proportionate evaluation, where practicable to do so. The Magenta Book is the recommended central government guidance on evaluation that sets out best practice for departments to follow. It is hoped, however, that it will be useful for all policy makers and analysts, including those in local government and the voluntary sector. It presents standards of good practice in conducting evaluations, and seeks to provide an understanding of the issues faced when undertaking evaluations of projects, policies, programmes and the delivery of services. The Magenta Book is not a textbook on policy evaluation and analysis – the field has plenty of such texts. Rather, it is written and structured to meet the specific and practical needs of policy makers and analysts working in public policy."
