The task you work on in the course: it comes back regularly in your work and eats up your time.
In module 1 you choose your time sink, assign it a stage and write down its steps. In the later modules you keep working on it, from the assignment and the project in Claude through to the action plan in module 12. If you do not have a time sink of your own, or you are unsure about your documents, you use the sample material of the planning office.
Example from Module 1
Planning office [example]: The time sink is the weekly report built from the hours list and the meeting notes.
Module 1: “Who presses the next button?”. In the Werkbank course room, with sign-in.
