Health care system addresses patient journey with subtraction

A healthcare system maps the patient journey and adds a chaperone to each step instead of removing any steps. To bust bureaucracy, it is important to subtract instead of adding. Researchers use a triangle-shaped bell called the 'no bell' to celebrate saying no. Competence is shown by subtracting, and subtraction can be built into processes. One simple way is the 'one in two out' rule.
