A team is going to follow their project manager’s examples. Therefore if he is lackadaisical his team is most likely going to slack off on assignments, thus causing a cascade of issues. It is important for a project manager to be communicative with his team, neat, and enthusiastic about all aspects of the project. Team motivation can be as simple as talking to the team members, and giving them positive feedback on what they are doing. A pizza party (or something of that manner) after the completion of a difficult task could be another form of motivation to keep the team striving for the best. By doing things like this the team members will know that the PM cares about them, and the task at hand; which will improve overall motivation, and mood of the team.
