This document discusses two major project killers - fear and complexity. It examines different types of fears that can undermine projects from customers, suppliers, project managers, and teams. These fears often lead to poor decisions if not addressed. The document also discusses how complexity is difficult to predict and that the traditional models of analyzing and planning everything upfront don't work for complex projects. It advocates for iterative and collaborative approaches like agile, PRINCE2, and Scrum which embrace uncertainty, learning, and small incremental steps to better handle complexity. The conclusion is that projects are more successful when the ability to learn is enhanced through collaboration, accepting uncertainties, and proving assumptions quickly.
