I believe that all the responses above have mentioned what are the best practices to form a good project team. from my personal experience. Most of the time, you do not get the chance to pick your team members or even your project (especially if you are a project manager). In a functional organization, the Project manager goes to each department and requests someone to work on their project. The trick here lies with the project manager who has to set the tone and environment to encourage team members to work and achieve their goals. One of the best project management methodologies I have seen so far, the project manager scheduled a project kickoff meeting, where he invited all team members, allowed each member to introduce themselves and highlight what their role in the project. The project manager explained in that meeting what are the project goals, expectations from each member, project milestones, and project timeline. He gathered input from each member to tailor the timeline based on the need of each department. He also scheduled a one hour status update meeting once every two weeks. This meeting is mandatory for all team members, where each each member will present their status and provide an explanation for any delays. This way seems to bring everyone on board.
