In order not to get bogged down in this flow and not lose the original goal, the workflow is divided into equal time iterations, the so-called sprints.
Sprints should not be too long.
They are usually measured in weeks from 1 to 4.
Tasks that are not included in the current sprint will automatically be transferred to the new one.
You can always change the content of a sprint by simply changing the sequence of tasks in a thread.
