Problem 1
Scope creep can be defined as a continuous increase in the scope of a project that can significantly increase project cost. Explain how a proper model of the system context can help prevent scope creeps.
Problem 3
You have been asked to develop a system that will help with planning large- scale events and parties such as weddings, graduation celebrations, and birthday parties. Using an activity diagram, model the process context for such a system that shows the activities involved in planning a party (booking a venue, organizing invitations, etc.) and the system elements that might be used at each stage.
Problem 5
Develop a sequence diagram showing the interactions involved when a student registers for a course in a university. Courses may have limited enrollment, so the registration process must include checks that places are available. Assume that the student accesses an electronic course catalog to find out about available courses.
Problem 6
Look carefully at how messages and mailboxes are represented in the email system that you use. Model the object classes that might be used in the system implementation to represent a mailbox and an email message.
Problem 7
Based on your experience with a bank ATM, draw an activity diagram that models the data processing involved when a customer withdraws cash from the machine.
Problem 9
Draw state diagrams of the control software for: an automatic washing machine that has different programs for different types of clothes; the software for a DVD player; the control software for the camera on your mobile phone. Ignore the flash if you have one on your phone.
Problem 10
In principle, it is possible to generate working programs from a high-level model without manual intervention when using model-driven architectures. Discuss some of the current challenges that stand in the way of the existence of completely automated translation tools.
