1. Which of the following is not a function of decomposition?
Permit different parts of the system to be built at the same time by the same person.
Allow attention to be concentrated on the part of the system pertinent to a particular audience, without confusing people with details irrelevant to their interests.
Facilitate the focusing of attention on one area (subsystem) at a time without interference from other parts.
Break a system into smaller, more manageable, and understandable subsystems.
Build different parts of the system at independent times and have the help of different analysts.

Question 2. The process of developing and maintaining an information system best describes:
joint application design.
prototyping.
information systems analysis and design.
information technology infrastructure development.
systems implementation.

Question 3. Identifying, assessing, and managing the risks and day-to-day changes that occur during a project best defines which of the following project manager activities?
Conflict management
Risk and change management
Team management
Customer relations
Technical problem solving

Question 4. An online or hard-copy repository for all project correspondence, inputs, outputs, deliverables, procedures, and standards that is used for performing project audits, orientation of new team members, communicating with management and customers, identifying future projects, and performing post project reviews is called:
a project workbook.
a schedule book.
a project planner.
project management software.
an electronic calendar.

Question 5. Which of the following would be classified as an intangible cost?
Hardware costs
Labor costs
Employee morale
Operational costs
Internet service setup fee

Question 6. Tangible benefits would include:
improved organizational planning.
ability to investigate more alternatives.
improved asset control.
lower transaction costs.
first to market.

Question 7. Which of the following is a modern method for collecting system requirements?
Interviewing
Questionnaires
Observations
Joint application design
Document analysis

Question 8. The purpose of requirements structuring is to:
enable the analysts to gather information on what the system should do from as many sources as possible.
enable the analysts to develop a baseline project plan quickly.
enable the large amount of information gathered during requirements determination to be organized.
enable the analysts to identify several feasible alternatives.

Question 9. Drawbacks to prototyping include:
a tendency to avoid creating formal documentation of systems requirements which can then make the system more difficult to develop into a fully working system.
prototypes becoming very idiosyncratic to the initial user and difficult to diffuse or adapt to other potential users.
prototypes are often built as stand-alone systems.
checks in the SDLC are bypassed so that some more subtle, but still important, system requirements might be forgotten.
all of the above.

Question 10. Technologies that enable the breaking of long-held business rules that inhibit organizations from making radical business changes best defines:
technology barrier breakers.
reengineered technologies.
disruptive technologies.
state-of-the-art technologies.
innovative technologies.

Question 11. A data-flow diagram that represents a system's major processes, data flows, and data stores at a high level of detail refers to a:
context diagram.
level-1 diagram.
level-0 diagram.
level-00 diagram.
logic diagram.

Question 12. The number of instances of entity B that can (or must) be associated with each instance of entity A refers to:
cardinality.
domain.
ternary occurrence.
participation level.
join level.

Question 13. Which of the following is a true statement regarding midrange alternatives?
Midrange alternative design strategies often do not involve computer technology; instead they focus on making paper flows more efficient or reducing redundancies in current processes.
Midrange alternative design strategies represent compromise solutions.
Functionality is the primary focus of midrange alternative design strategies.
Midrange alternative design strategies provide all the required functionality users demand with a system that is minimally different from the current system.
Midrange alternative design strategies provide all the desired features using advanced technologies that often allow the system to expand to meet future requirements.

Question 14. Reversing the sequence of one or more characters in a field is called:
transposing.
transcripting.
appending.
truncating.
hashing.

Question 15. The primary deliverable from logical database design is:
normalized relations.
design specifications.
an updated Baseline Project Plan.
a list of alternatives design strategies.
a production system.

Question 16. Commonly used methods for highlighting include each of the following EXCEPT:
reverse video.
boxing.
spacing.
underlining.
all capital letters.

Question 17. A notation that allows the modeler to specify, visualize, and construct the artifacts of software systems, as well as business models, best defines:
Unified Modeling Language.
Structured English.
pseudocode.
logic modeling.
structured design.

Question 18. Benefits of the object-oriented modeling approach include:
the ability to tackle more challenging problem domains.
improved communication among users, analysts, designers, and programmers.
reusability of analysis, design, and programming results.
increased consistency among the models developed during object-oriented analysis, design, and programming.
all of the above.

Question 19. User testing of a completed information system using simulated data refers to:
acceptance testing.
alpha testing.
beta testing.
system testing.
stub testing.

Question 20. Changing over from the old information system to a new one by turning off the old system as the new one is turned on best describes:
phased installation.
single location installation.
parallel installation.
direct installation.
rotation installation.

Question 21. List and briefly describe the four major SDLC phases.

Question 22. Discuss the six major categories of feasibility.

Question 23. Identify and describe the traditional methods for determining requirements.

Question 24. Discuss how DFDs can be used as analysis tools.

Question 25. Define the following key data modeling terms: entity, attribute, relationship, degree, cardinality, and associative entity.

Question 26. briefly discuss generating alternative design strategies.

Question 27. Identify and describe validation tests and techniques used to enhance the validity of data input.

Question 28. Describe four benefits of the object-oriented modeling approach.
