The local motel decides to use statistical process control to monitor the consistency of its housekeepers. The owner periodically inspects rooms after the housekeeper has cleaned. These checks involve making sure'the beds are made, the trash can is emptied, coffee supplies are replenished, and the toilet paper has that neat little triangle at the end of the roll. What type of control chart should be made for this situation?
