Category: Rules and Principles

You decide to take a break from riding roller coasters and enter the amusement park cafeteria. You stand in the food line, and realize you forgot a tray. You walk across the room to get a tray and then back in line. With food in hand, you are now struggling to locate silverware and napkins. The cashier instructs you to obtain napkins at the back of the cashier line and then directs you to obtain your silverware in the middle of the room at the self$-$serve soda machine. This layout is a direct violation of which Lean Rule:

Specify and Simplify Every Flow Path

Clearly Connect Every Customer$-$Supplier

Structure Every Activity

Improve Through Experimentation
