What you like to sell as a product tomorrow, you need to develop by a project today. A company needs to run a portfolio containing many of such research and development (R&D) projects and often has even more ideas which projects it still should add. The management of such a portfolio involves important decisions on which projects to run, which ones to abandon, how to prioritise them, and how to allocate the resources. And it should strive for a transparent overview for making sure your project portfolio brings you there where you want to be. This book, first, gives a comprehensive overview of approaches and methods for R&D portfolio management. Second, it presents the results from a study done at Swedish industrial companies and offers many experiences and insights from their practice. The reader of this book is offered an overview of this topic. Students and academics can make further use of the broad spectrum of referred authors and literature. And managers benefit from the suggested approaches and the insights from many studied company practices.
