• Why might it make sense to learn UP disciplines and activities sequentially, as in the waterfall approach, even though in practice iterations are used in nearly all development projects?

• Teaching UP disciplines and activities sequentially like a waterfall helps to organize the course and helps to explain the specific work that is done in each UP phase. Teaching an iteration approach first can confuse the work that is done in different UP disciplines

• List some of the models that architects create to show different aspects of a house they are designing. Explain why several models are needed.

• Blue prints showing: floor plan, front and rear elevation, roof framing plan, plumbing layout, electrical layout, foundation, and placement of house on lot. There can be other models: a scale 3D model of what the house looks like, mathematical calculations defining stresses and forces affecting the roof or walls. Each model “abstracts” or highlights certain aspects of the house. No one model can contain everything needed. All models must fit together to define a house.

TC 7TC 7

• Describe a "technique" you use to help you complete the activity "Get to class on time." What are some “tools” you use with the technique?

• A technique is a strategy for completing an activity. So a strategy for getting to class on time might include suggestions like set the alarm, get to bed early, check the class schedule each night, check the bus schedule over breakfast, etc. The tools would be the alarm, the class schedule, and the bus schedule.

• Is the proposed systems an accounting system? A factory operations system? Or both?

• Systems today are very integrated – it is difficult to define where one system ends and the other one begins. The factory operations system draws on inventory accounting data when items are manufactured, and then it creates updates to the finished goods inventory accounting data. One system cannot work without the other. An analyst increasingly needs to be aware of the overall business processes of the company. Additionally, an analyst needs to be aware of the overall strategic plan to see how the systems fit together.

• Which approach might be more appropriate for this project, a predictive approach or an adaptive approach? Discuss.

• An adaptive approach will be more appropriate for this project, because the exact requirements of the system and the needs of the users are not well understood. Sally should use some form of extensive user participation to get as much input from users in the factory as possible. She doesn’t know much about the factory, so she needs to rely on the experts to help her define the business needs, requirements, use cases, and so on.

• Which activities of the UP disciplines discussed in this chapter should involve factory workers and factory management?

• Ideally factory workers and factory management should be involved throughout the total UP. Their involvement is especially important within several disciplines. In the Business Modeling discipline, they should participate in defining the problem the system must solve, the system objectives, and benefits. Within the Requirements discipline, they should help define the problem domain, the requirements and their priorities, develop the user interface dialogs, and evaluate requirements. In the Testing discipline, they will probably be most involved in usability and user acceptance testing. In the Deployment discipline, they may be involved and training other users.
