Fifteen minutes, on the last day of a round or the day after. It gives the round a proper end, and it writes the handoff the next round starts from.
Done when the round is marked Done, its Handoff field is filled in, and the next round has a start date or a dated note saying when you will decide.
The finish line. Copy it from the round. Did you reach it, reach part of it or change course? Each of these is a result. Write which, in a line.
What got done. Open the round and look at the ticked tasks in its Tasks list. A sentence will do.
What you decided, and why. The choices you made about the project this round, including the ones you made by default.
What is open. Questions still unanswered, tasks you kept moving to Next and notes left in the inbox.
Tidy the tasks. Move anything that no longer matters to Later, or delete it. Choose three Now tasks for the next round.
Rest. How long before the next round starts? Put the date on the next round in Rounds, even if it is a date to decide.
The project. Is it still Active? If the finish line is reached, mark it Finished and write what it became.
When you are done, copy your answers to 1, 3 and 4, and the first Now task, into the round's Handoff field, and mark the round Done.
