This book is concentrating on leadership in projects, in particular project managers and their leadership responsibilities. Project leadership concerns how the project manager creates direction, progress and cooperation to ensure that the organization does the best possible job in achieving the project s goals. With both a business and a global perspective, this book presents new research on challenges in the project manager role, changes and collaboration in projects. The authors also provide insight into what it takes to deal with challenges, based on wide-ranging research in project management and leadership over the past 20 years.
