EZS is a small fast food outlet serving mainly freshly prepared, customizable line of sandwiches. It is supplemented with an assortment of drinks, light salads, seasonal fruit and snacks. A customer joining the line makes a sandwich selection by consulting the billboard, and marks her selection on a customized form. She then hands the form to an assembler who produces the sandwich while she moves on. The customer does not wait for the sandwich to be assembled, but proceeds directly down the line to select additional items onto her tray. Next, the customer proceeds to pay at the cash register. Finally, (after the payment is completed) she collects her prepared sandwich at a designated location. Selecting the sandwich and marking the form takes 30 seconds. Assembling the sandwich requires 90 seconds. Selecting additional items takes 60 seconds. Paying at the cash register requires 40 seconds. Collecting the prepared sandwich requires 20 seconds. Another improvement option considered (instead of the one in the previous part) is limiting the number of additional items available thereby reducing the expected time of making a selection from 60 to only 40 seconds. Using AI to answer quiz questions is prohibited. What is the expected effect on the theoretical flow time of the process?
