In a survey with 10,000 Project Managers it was found that over 60% of the issues that impact
project performance is associated to the people side of the project, while management and
leadership issues account for over 75% of all project failures. If on one side, people are the
greatest source of uncertainty in a project, on the other, they are also the most important
resource to reducing risks, when properly managed (Thamhain, 2013).
