a. Another name for component-based development.

b. A useful approach when a customer cannot define requirements clearly.

c. A high speed adaptation of the linear sequential model.

d. All of the above.

20. Evolutionary software process models ()

a. Are iterative in nature

b. Can easily accommodate product requirements changes

c. Do not generally produce throw away systems

d. All of the above

21. The incremental model of software development is ()

a. A reasonable approach when requirements are well defined.

b. A good approach when a working core product is required quickly.

c. The best approach to use for projects with large development teams.

d. A revolutionary model that is not used for commercial products.

22. The spiral model of software development ()

a. Ends with the delivery of the software product

b. Is more chaotic than the incremental model

c. Includes project risks evaluation during each iteration

d. All of the above

23. The concurrent development model is()

a. Another name for the rapid application development model.

b. Often used for the development of client/server applications.

c. Only used for development of parallel or distributed systems.

d. Used whenever a large number of change requests are anticipated.

24. The component-based development model is()

a. Only appropriate for computer hardware design.

b. Not able to support the development of reusable components.

c. Dependent on object technologies for support.

d. Not cost effective by known quantifiable software metrics.

25. Describe the phases of the prototyping model for software development?

Answer:Requirements are gathered by having the customer and developer meet and identify whatever objectives and requirements they can. Quick design follows, focusing on representation of the software that will be visible to the customer. A prototype is constructed by the developer and evaluated by the customer and used to refine the requirements. Iteration occurs and the prototype is tuned to satisfy the customer's needs.

26. Describe the role of risk analysis in evolutionary process models like the spiral model.

Answer:As each prototype is enhanced by iteration through the process steps, both the technical and management risks are assessed to see if it is still possible to compete the project which its required functionality with acceptable time and cost constraints.

27. Effective software project management focuses on()

a. people, performance, payoff, product

b. people, product, performance, process

c. people, product, process, project

d. people, process, payoff, product
