Two things stop work quietly: a problem nobody owns, and a shift change where the open work is forgotten. Problems gives every issue a person and a fix-by time. Handover carries what is still open from one person to the next.
Problems / Open. Three columns: New, Being fixed, and Fixed, waiting for check.
One handover. Open work is pulled in by itself; the person leaving adds notes, cash and keys.
No setup fee. No charge per branch.
