A) Parallel
B) Direct
C) Phased
D) Pilot
E) Traditional

Question 15

A bank upgrades the computer systems of its branches, one branch at a time. This is most likely which of the following migration strategies?

A) Parallel
B) Direct
C) Phased
D) Pilot
E) Traditional

Question 16

The Build phase of the SDLC is used to ensure that the software is properly integrated with the other components of the information system.

Question 17

The SDLC and prototyping methodologies are one and the same.

Question 18

Both the SDLC and prototyping methodologies are use d to create custom systems.

Question 19

Off-the-shelf systems enable infusion of knowledge in the organization

Question 20

End-user development: The process by which an organization's non-IT specialists create software applications.

Question 21

Custom software development is a systems development approach predicated on the notion that it impossible to clearly estimate and plan in detail such complex endeavors as information systems design and development projects.

Question 22

A system analyst is a highly skilled IT professional who takes the system requirements document (i.e., what the applications should do) and designs the structure of the system (i.e., how the application will perform its tasks).

Question 23

What are two advantages to custom developing and designing a software application?

Question 24

Name two advantage to purchasing off-the-shelf software

Question 25

Name, in order, the principal phases of the SDLC

Question 26

Name and describe the four approaches to software installation

Question 27

Occasionally, _________ will be used within the SDLC as a way to elicit user requirements and seek input in the design of the user interface.

Question 28

When purchasing off-the-shelf applications, a selection process similar to the SLDC is used-the only difference being one additional phase in the process. What is the name of this phase and where does it occur in the process?

Question 29

List and describe two benefits of End-User development

Question 30

We have discussed the notion of "make and buy" as a new trend that challenges the traditional "make vs. buy" paradigm. Briefly explain what we have meant by "make and buy" and provide an example.

Question 31

List and describe two risks of End-user development. Make sure to include at least two examples of each.

Question 32

Feasibility analysis is required to justify IT investments. Along with user requirements this is where user-managers have the greatest input. Briefly describe the purposes of the technical feasibility analysis, the economic feasibility analysis, and the behavioral feasibility analysis.
