Question 2:

1. Describe and compare the various sources of software.

2. How can you decide among various off-the-self software options? What criteria should you use in your decision?

3. What methods can a systems analyst employ to verify vendor claims about a software package?

Give a brief overview and history of CASE.

1) What are the basic categories of CASE? (Hint: There are usually three)

c. project initiation vs. project planning vs. project execution vs. project closedown
d. project workbook vs. resources vs. work breakdown structure (WBS)

2. List the various project team communications methods, plus, describe an example of the type of information that might be shared among team members using each method.

Question 4:

1. Describe the project identification process.

2. Describe value chain analysis and how organizations use this technique to evaluate and compare projects.

3. Describe the steps involved in corporate strategic planning.

Question 5:

1. Contrast the following terms and concepts:

a. break-even analysis vs. present value vs. net present value vs. return on investment.
b. Intangible benefit vs. tangible benefit

2. List and describe the steps in project initiation and process planning.

Question 6:

1. Describe systems analysis and the major activities that occur, during this phase of the systems development life cycle.

2. Describe how prototyping can be used during requirements determination. How is it better, or worse, than traditional methods?

3. Why is continual user involvement a useful way to discover system requirements? Under what condition might it be used? Under what conditions might it not be used?

Question 7:

1. What is DFD? Why do systems analysts use DFDs? Briefly explain the rules for drawing good DFDs.

2. Explain the convention for naming different levels of DFDs. Why do analysts draw multiple sets of DFDs?

Question 8:

3. Discuss why you believe some systems developers feel a data model is one of the most important parts of the statement of information system requirements.

4. Distinguish between the data modeling done, during information systems planning, project initiation and planning, and the analysis phases of the SDLC.

5. List the deliverables from the conceptual data modeling part of the analysis phase of the systems development process.

Question 9:

1. What is the purpose of normalization? List the five properties of relations. What problems can arise when merging relations? (Hint: view integration)

2. Can instances of a relation (sample data) prove the existence of a functional dependency? Why or why not?

3. What is the purpose of denormalization? Why might you not want to create one physical table or file for each relation in a logical data model? Please explain your answer.

Question 10:

4. Describe the prototyping process of designing forms and reports. What deliverables are produced from this process? Are these deliverables the same for all types of system projects? Why or why not?

5. In your opinion, what type of labeling can you use in a table or list to improve its usability? What column, row, and text formatting issues are important when designing tables and lists?

Question 11:

1. Contrast the following terms and concepts:

a. dialogue vs. interface
b. command language interaction vs. form interaction vs. menu interaction vs. natural language interaction vs. object-based interaction
c. drop-down menu vs. pop-up menu

2. Describe the general guidelines for the design of menus. Can you think of any instances when it would be appropriate to validate these guidelines? Please explain your answer.

Question 12:

3. Summarize the six (6) possible architectures for client/server systems.

4. Summarize the reasons for using three-tiered client/server architecture.

5. Discuss how you can instill customer loyalty and trust worthiness when designing an Internet-based electronic commerce system.

Question 13:

1. What are the deliverables from coding, testing, and installation?

2. Explain the code-testing process.

3. What are the four approaches to installation? Which is the most expensive? Which is the most risky? How does an organization decide which approach to use?

4. What are the common methods of computer training? What is self-training? What is eLearning? In your opinion, is there proof that individual differences matter in computer training?

5. Describe the various roles typically found in a help desk function.

Question 14:

6. Contrast the following terms and concepts:

a. adaptive maintenance vs. corrective maintenance vs. perfective maintenance vs. preventive maintenance

b. baseline modules vs. build routines vs. system librarian

c. maintenance vs. maintainability

7. List the steps in the maintenance process and contrast them with the phases of the SDLC.

8. Describe three ways for organizing maintenance personnel and contrast the advantages and disadvantages of each approach.

9. What types of measurements must be taken to gain an understanding of the effectiveness of maintenance? Why is tracking "mean time," between failures, an important measurement?

10. Suppose you were a system librarian. Using entity-relationship diagramming notation, describe the database you would need to keep track of the information necessary in your job. Consider operational, managerial, and planning for the job.
