Eleven Common Mistakes Made by New or Inexperienced Project Managers


Harold Kerzner, Ph.D., PMP 


The list below shows eleven of the most common mistakes that young or inexperienced project managers make. Obviously there are more than eleven 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.

MISTAKE #1: Pretending to Know More than You Actually Do 

Generally, project managers today possess an understanding of technology rather than a command of technology, yet persist in trying to make technical decisions on the project. This usually infuriates line managers, causing them to show who is boss.

The size and complexity of today’s projects should make it clear to project managers that they must rely heavily upon the assigned subject matter experts and functional leads for technical direction and support. On some projects, such as in R & D, project manager assignments may be dictated by a requirement for a command of technology rather than just an understanding, but this is an exception rather than the rule. Good project managers know their limitations and never try to dictate a solution without first consulting with the true experts.

MISTAKE #2: Preparing an Ambitious Schedule 

The more inexperienced the project manager, the more optimistic he or she becomes when preparing the schedule baseline. While ambitious schedules are nice to have, they are often unrealistic and can make matters worse. Customers are never told that the schedule is ambitious and therefore believe the schedule is realistic. The customers then focus on the milestone dates and now, when the milestones slip from ambitious to reality, you have an unhappy customer who wonders what other surprises will show up next.

Another factor to consider is the impact on the functional estimates. Ambitious schedules may require team members to perform at a higher position on the learning curve thus changing the functional standards. Functional managers may not want their estimates and standards to be changed. Also, ambitious schedules may require the company’s best functional workers to be assigned to the project and this may be unrealistic.
