This course made me think more about how important the interactions between people are to ruining a project. A good PM is important but if you have people in the group that are lagging behind others than that makes a project that much more difficult and can lead to timeline changes, going over budget, etc. The possibility of others in your team falling behind or not communicating to one another puts more stress on the PM to manage so the project does not fall behind or at worst get canceled altogether.
