Campus Bikes

Campus Bikes sells several brands of new bikes, including everything from high-end racing models to beach cruisers. In addition to sales of new bikes and accessories, Mark’s service department is always busy. The staff includes Mark himself, a bookkeeper, two part-time sales reps, a full-time mechanic, and several part-time service helpers who assemble bikes. Before opening the shop three years ago, Mark worked for many years in his father’s auto dealership. Turner Motors, and he learned all about the automobile business. In the bike shop, he runs a similar operation, but on a much smaller scale. For example, sales orders are recorded on pre-printed forms, and service requests are written up just as they would be in an auto service department. Mark’s customers find him fair and reasonable. He likes to say that the main difference between his business and a big-box retailer is that he knows his customers and will do whatever it takes to keep them happy. You work at the college as a lab assistant in the computer information department. You earned a computer science degree at a two-year school, and you recently decided to work toward your four-degree. The computer lab manager, Jill, often suggests that local businesses contact you for help in troubleshooting IT issues. This morning, you received a call from Mark, who wants to hire you as a consultant to help plan a system for Campus Bikes. You learned that Jill had referred him, and you are excited to have this opportunity. It probably didn’t hurt that both you and Jill had bought bikes from Mark. and already knew him. After spending several weekends talking with Mark and the staff, you are ready to start. You decide to use an object-oriented approach that will be easy to understand. Tasks 1. List possible objects in the new bike shop system, including their attributes and methods. 2. Identify at least three possible use cases and actors. 3. Create a state transition diagram that describes typical customer states and how they change based on specific actions and events. Part II:

Until now, the owner, Mark Turner, kept the business records on his personal computer. He created a simple database to keep track of inventory, but it is not always up-to-date. He also developed spreadsheets to track expenses and payroll. The business has grown and Mark wants to install a new computer system to handle all business functions. ISYS 463 Individual Assignment #3 You are a student in the information systems department at the college. You were recently hired by Mare and he asked you to help him plan a system for Campus Bikes. You used an object-oriented approach to create a model of the business functions and actors involved. Now Mark wants you to do a “make or buy” analysis. Specifically, you will look into the pros and cons of in-house development versus purchase of a software package. Your research indicates that the most popular bike shop package is offered by a vendor called BikeData. In your last meeting. Mark said that tangible savings for a new system would be hard to measure, but improved customer care, better service department records, and increased productivity are expected. Mark estimates that these benefits will add up to about $6,000 per year, whether the system is developed in-house, or purchased from BikeData. You decide to compare relative costs to establish a total cost of ownership (TOC) over the useful life of the system. Based on your research, you put together the following summary: In-house development option • The system will have a six-year useful life, be very flexible, and easiest to maintain. • It will cost $16,000 to develop, install, and configure the system, and $1,500 to load existing data. • Mark and the bookkeeper can handle day-to-day support with no added expense. BikeData software package option • This is a vertical package with a four-year useful life. • The software is less flexible than an in-house system and some customizing will be needed. • It will cost $8,500 to purchase, $1,000 to install and configure, $2.000 to load existing
