4.16 Part A of the Magenta Book has given an overview of the key issues in policy evaluation, where it fits in the policy cycle, what benefits good evaluation can offer and some of the things to consider when planning and undertaking any evaluation activity.
4.17 Part B is aimed primarily at an analytical audience and therefore more technical, though it will be relevant too for interested policy makers. It covers in more detail some of the issues, challenges and steps to take in planning and undertaking an evaluation, including the setting of an evaluation framework, process and impact evaluation design and approaches to the interpretation and assimilation of evaluation evidence.
