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.

d. Consider the same narrative as described in the beginning. Model the process with two pools, message flows, and intermediate message events.

a. Pools represent participants in a process. Which of the following is the best name for the pool representing the external participant?

• Starbucks

• Baristas

• Customers

• Drive-through lane

• None of these

b. Which of the following is most likely to be a name of a message flow coming into the Starbucks pool?

• Customer Order

• Delivered Order

• Answers to Customer Questions

• Customer Receipt

• None of these

c. Models often show the pool for the external participants as opaque. What are the advantages of this?

• Focuses on the message flows and activities for the internal participant

• Ignores activities in the external participant pool that are not relevant

• Reduces the complexity of the model

• Focuses on controllable process activities

• All of these

d. Intermediate message events can be catching or throwing. The events catch incoming message flows and throw outgoing message flows. Which of the following message flows could connect to an intermediate catching event in this process?

• Delivered products

• Customer payments

• Customer receipt

• Answers to customer questions

• None of these

e. Intermediate message events can be catching or throwing. The events catch incoming message flows and throw outgoing message flows. Which of the following message flows could connect to an intermediate throwing event in this process?

• Customer order

• Customer payments

• Customer receipt

• Answers to customer questions

• None of these

f. Which of the following is required if you include any tasks or other BPMN elements in the Customers pool?

• The sequence flow in the Customers pool must flow continuously from the start event to end events

• The message flows still connect to the edge of the Customers pool regardless of whether or not the pool is opaque

• You do not need to show message flows if you include activities in the Customers pool

• The Starbucks pool can be opaque if you include the activities in the Customers pool and the message flows

• None of these
