20 Common Mistakes Made by New or Inexperienced Project Managers
By Harold Kerzner, Ph.D
Abstract
Even experienced project managers can make mistakes. Most project management training courses, even those focusing on the PMBOK® Guide, stress “generally accepted best practices.” What is not taught are discussions on what not to do as a project manager. This White Paper shows twenty of the most common mistakes that young or inexperienced project managers make. Obviously, there are more than twenty mistakes, and many of these may be unique to specific industries. However, the list is a good starting point for understanding why many project managers get into trouble because of their own doing.
