"PE 4-8. Consider the following narrative (initially introduced in PE 2-8): Copies R Us (CRU) is a copy shop and office service center operating in downtown Boston. To be able to compete with the large chains, CRU is open twenty-four hours per day and offers a wide variety of printing and image processing services at affordable prices and with friendly service. CRU divides its main products and services into categories (such as black/white copies, color copies, collating, binding, computer usage, faxing, etc.). A large number of products and services belong to each category, and the categories, products, and allocation of products to categories change dynamically. A job consists of all products and services that a customer orders at the same time (for example, a marketing brochure job could consist of color copies, collating, folding, and binding). Currently, a customer comes to an agreement regarding the required job(s) with the service representative, who creates a service ticket that CRU technicians will use to perform the work. It is important that the system maintains information about the time when each job was entered into the system and details describing all the components of the job and any special requirements the job has. CRU maintains a priority order for the jobs. This order is normally based on the time a job was registered to the system, but the store manager on duty can override the priorities. CRU serves both individual and business customers. All business customers are identified by CRU before they can attain business-customer status, which allows them to be invoiced for the work they have requested CRU to perform. Each business customer negotiates a separate discount percentage for each of CRUs product categories. CRU does not always know the identities of individual customers, but it encourages its customers to get a Most Valued Customer (MVC) card, which gives its holders volume discounts, depending on the amount of work they request CRU to perform annually. Getting an MVC card, of course, requires the customer to provide CRU with his contact information. Individual customers pay for their purchases at the time they pick up their jobs (either by cash or credit card); as mentioned earlier, business customers can also be invoiced periodically (e.g., once a month), and thus one invoice can cover multiple jobs. CRU has several resources that cannot be used by more than one customer at a time (such as a couple of conference rooms with videoconferencing capabilities and several computers). CRU needs to maintain reservations for these resources. Business customers can make multiple reservations. Only individual customers with the MVC card can make reservations at all, and an MVC customer can have only one reservation at a time. A. Identify (with a brief label) all user stories and write out at least one of them (if any exist) for each of the following personas in the context of this narrative: a. Copies R Us individual customer b. Copies R Us business customer c. Copies R Us representative d. Copies R Us technician B. For each of these user stories, develop wireframe(s) that illustrate the key elements of the process the user will follow to achieve her/his goal(s) within the context of the user story. Illustrate the key navigation options between the wireframes. C. For each user story, select one wireframe and expand it to a mock-up by including the key controls and sample data. D. Based on what you learned through the process of developing the user stories and UI models, describe what changes you would recommend to the business process you developed in PE 2-8."
