“When do I remove tickets from the DONE column?”The short answer is, every week or so, try to have a short retrospective with your team or alone (if you are working by yourself). When you have the meeting, review what’s happened and archive as you do.Some of the tasks in your DONE column will spark introspection, some won’t. (Hopefully you don’t have to ponder all your work).As you discuss the tasks, you can move them into your ARCHIVE where you store completed tasks. Or, if you are so inclined, you can throw them away.In the video, the ARCHIVE is part of the software. With a physical board you can have your archive be a file folder or a shoebox.
