Clean laundry keeps collecting on a chair. Clearing it once helps today; the pile returns if more arrives than gets put away. You can examine that pattern without deciding that someone is lazy or that every problem needs a complicated diagram.
A system map shows the parts and relationships you think matter. The clean-laundry examples in this course show how a few words and arrows can help you understand a recurring problem and choose a small change to try.
A map is a proposed explanation. Recurrence is a reason to investigate; it does not prove a particular cause.
