draw a system blueprint for the following business scenario:

You use your mobile phone, click the app and fill the necessary information into the form to select the coffee you would like to order. Submit the form and make the payment online. The coffee store staff receives the online order and makes the coffee, then notify you online that the coffee is ready for pick-up. After receiving the notification, you walk to the store, check the name on the coffee cup and pick up the coffee.
