From the perspective of delivering successful projects, the value of a skilled project sponsor and project manager outweighs many other factors. Projects need leaders who can give them vision, identity, keep the stakeholders and the project team on board and make the difficult decisions that will enable the project to continue (or, if necessary, be terminated). These are human skills that don't necessarily feature large in the project management bodies of knowledge. Ralf Müller and Rodney Turner's Project-Oriented Leadership explains the key leadership models of managerial, intellectual and emotional leadership and shows how they can be applied within projects to lead processes, functions and people, and ensure an ethical and inclusive approach within projects and programs.
