Consider the following narrative describing the process of filling a customer's order at a Starbucks branch: Identify the start and end events and the activities in the following narrative, and then draw the business process model using BPMN: the Starbucks customer entered the drive-through lane and stopped to review the menu. He then ordered a Venti coffee of the day and a blueberry muffin from the barista. The barista recorded the order in the cash register. While the customer drove to the window, the barista filled a Venti cup with coffee, put a lid on it, and retrieved the muffin from the pastry case and placed it in a bag. The barista handed the bag with the muffin and the hot coffee to the customer. The customer has an option to pay with cash, credit card, or Starbucks gift card. The customer paid with a gift card. The barista recorded the payment and returned the card along with the receipt to the customer.

Consider the same narrative as described in the beginning. Add an intermediate error event to account for the possibility that the coffee the customer ordered is brewing and will not be ready for 5 minutes. When that happens, the Starbucks barista asks the customer if he/she wants to wait or wants another coffee.

Which of the following is used to represent an intermediate error event?

a. Place the intermediate error symbol on the perimeter of the task
b. Use a gateway after testing whether coffee is ready
c. Add a circular arrow to the symbol showing that the process repeats
d. Add an intermediate timer event showing that the process is delayed
e. None of the choices are correct.
