Timeline and the finish date
Two finish dates, and the list of what would make them agree.
Known and estimated
The Timeline page gives two dates. The known finish uses only what somebody has committed to: tasks on a week with an estimate, and orders with a delivery date. The estimated finish covers everything, filling each gap with a stated assumption, such as an undated order arriving in four weeks and an unestimated task taking two days.
An administrator can change those assumptions on the page.
What is missing
Under the dates are three lists: orders with no delivery date, tasks on no week, and tasks with no estimate. Each line says how much work waits on it. Fill them in and the two dates meet.
