A project manager can't manage a project alone. He has to include people with a range of different qualifications and experience on the team and ensure that they are suitably motivated .
Step 1 – Forming 
Form your team. The stakeholder analysis shows you which departments and individuals have to be involved in the project. First of all, talk to your customer about the people who you intend to include in your team. Then form your core team.
Step 2 – Storming
Get the creative chaos under control as quickly as you can. You can do this in an official team building workshop where all aspects of project planning can be discussed. Never omit the informal part. Allow project team members to satisfy their "social needs" (getting to know each other, team development, appreciation of their work etc.).
Step 3 – Norming
You have to help your staff to quickly fuse as a team! Give your team a project identity by defining a vision, motto, slogan and logo for the project. That breathes life into the project and motivates the team.
Step 4 – Performing
After steps one to three, the project team members are capable of targeted project planning. Do remember, though, that some of your project team members will leave the team at phase transitions and it may be necessary for new people to join the project. Remember to thank team members who leave the project and help new project team members to integrate themselves in the project. It may be necessary to arrange another brainstorming session.
Step 5 – Adjourning (only autonomous project organisation) 
Some project team members will seek new challenges before the project is officially closed out. Others will attempt to reopen work packages that have long been closed out in order to continue working on the project. You have to be prepared for project team dissolution and be aware of the best way to dissolve your team.
