Project success starts and ends with project leadership. We know that as project leaders we cannot succeed by ourselves. We need the help and support of our teams. This is why it is important to build teams and empower them to perform and deliver. The five leadership principles can be applied by a single person, the project leader, or the whole team. In either way, they help create the context for high-performance teams. Involving the complete team in building a project vision, nurturing collaboration, promoting performance, cultivating learning, and ensuring results help create an atmosphere of mutual respect and commitment toward the project vision as well as the other leadership principles. It is team leadership that helps secure project success. Leadership is about growth, for yourself, your relationships, your productivity, and your people.
