Organisations increasingly use projects to undertake major as well as smaller tasks. Projects help target and delimit activities, place the responsibility and transfer risk from the financing to the implementing party. As a result, evaluation has become popular as a tool to control, guide and draw lessons of experience from projects. This book is intended both as a textbook for students and a handbook for practitioners. It provides hands-on easy to comprehend lessons about evaluation as a phenomenon, its design, preparation and methodology - as well as the project as a management tool. Knut Samset is professor at the Norwegian University of Science and Technology and director of a major research program on front-end management of projects. He has written internationally published books on project design, evaluation, and project risk management.
