The kick-off meeting is the formal start of the project or a project phase. It is an opportunity for the project manager to communicate the project objectives, scope, schedule, risks, assumptions, and expectations to the project team and other stakeholders. It also helps to establish the team roles and responsibilities, the communication plan, the ground rules, and the team culture. The kick-off meeting is part of the Develop Project Management Plan process, which belongs to the Planning process group. The other options are not the actions that the project manager should do in this phase, as they are either part of other processes or not relevant to the project baseline schedule development. References:
