Waiting for

In GTD, the list of things you have handed to someone else and still care about — a request sent, a task delegated, an order placed — each with who and when, so that the follow-up is a next action of yours and not a worry

The list that turns delegation from hope into a system: the item leaves your next actions and lands here with a date, the weekly review reads it, and an overdue one becomes a next action to nudge. Half of what people carry in their heads is on this list once it exists. The workflow figure sends delegate it here.
