Once the project has been completely planned, the project plan is approved by the key stakeholders. This is when a Kickoff meeting is held. This meeting is not for reviewing the plan. The plan has already been approved. This meeting is to open communication channels between all stakeholders. Some of the discussions that happen during such a meeting are key project resource introductions, walkthrough of performance reports that would be sent and review of upcoming risks. Immediately after this meeting the project execution work is started.
