The project kickoff meeting is your first project team meeting. With just a little care, you can set a positive tone for the whole project.
If you haven’t yet written the project charter, you can use the project kickoff meeting to write the charter with the team. You have the answers to what’s driving the project (see Decide on a Driver for Your Project), and you can use the kickoff to write the charter as a team (see Write a Project Charter to Share These Decisions).
If you have written the charter, hold a walk-through of the charter. This helps people see how to start reviewing work products, as in Get Multiple Sets of Eyes on Work Products.
