Mistake #5: Poor interactions within your team and with clients
The last, but not least, most common mistake project managers make when managing multiple projects is inefficient communications. Poor communications within a team lead to misunderstandings and therefore to mistakes in project work. If your project lacks communication with clients, you and your client might end up with two different project visions as a result. In any case, miscommunication will result in loss of time and money, as well as in increasing your stress.
