What this page is — The standing teams your organisation plans with: who is in each team, in which role and at what share of their time, who leads it, and which projects it plans in. Teams live in Organization Settings; each project picks the teams that plan in it.
What this page is — Everything that happens before and around the planning itself: creating a PI session, the Brief tab where the facilitator decides which team plans which category, publishing, and the Team boards tab where each team plans its own work.
What this page is — How a customer contract that is priced by milestone becomes traceable money on the plan: the amount on each Milestone, the share each contributing task carries, and the Value tab that reads it all back.
