People on campus drink coffee-- students, professors, staff, etc., drink coffee, many of them every day. They can go to a coffee shop on campus, such as Starbucks or Java City, order coffee there, and go back to work, or class.

You can order coffee online, using the Tapingo mobile application, but you still need to walk there to get your order.

I need help with drawing a diagram to this software requirement specification please.

We introduce the new application UCD (University Coffee Delivery); in UCD you also order a coffee beverage online. But you can order from any physical location, even off campus. Commuters who are on their way to campus, who are passing by the coffee shop, and are willing to deliver the drink to you will be assigned to do so.

In the future, we could add delivery of other types of food and drink, from various types of food places -- similar to Uber Eats, Grub Hub, etc.

The purpose of Homework 2 and Homework 3 is to learn how to write a fairly complete and precise requirements specification, which is a critical step in developing a large software system. Completing these assignments will give you experience in one of the most interesting and difficult software engineering tasks.
