Within your group, assign some of the roles that people take on in agile development. Make sure that one person is an onsite customer and at least two people are programmers. Assign other roles, as you see fit. Simulate the systems development situation discussed in Problem 7, or have the person acting as the onsite customer choose an ecommerce business with which he or she is familiar. Assume that the customer wants to add some functionality to his or her Web site. Role-play a scenario showing what each person would do if this was being approached through agile methods. Write a paragraph that discusses the constraints that each person faces in enacting his or her role.
