Two part time boxed meeting: 8h/1m sprint. The work to be performed
in the Sprint is planned at the Sprint Planning Meeting. This plan is
created by the collaborative work of the entire Scrum Team. The two
part of activities need to be discussed are
1. Defines what will be delivered in the increment:
