using critical success factors, and determining requirements
from the IS plan can be used. Often, screen and report layout
charts are used to document requirements during systems
analysis.
Like traditional analysis, problems or potential oppor-
tunities are identified during object-oriented analysis.
Object-oriented systems analysis can involve using diagram-
ming techniques, such as a generalization/specialization
hierarchy diagram.
CHAPTER 12: SELF-ASSESSMENT TEST
Effective systems development requires a team effort from
stakeholders, users, managers, systems development special-
ists, and various support personnel, and it starts with careful
planning.
1.
8. System performance is usually determined by factors such
as fixed investments in hardware and related equipment.
True or False?
9.
____________________
takes an iterative approach to
the systems development process. During each iteration,
requirements and alternative solutions to the problem are
identified and analyzed, new solutions are designed, and a
portion of the system is implemented.
10. Joint application development (JAD) employs tools, tech-
niques, and methodologies designed to speed application
development. True or False?
__________________ is the activity of creating or mod-
ifying existing business systems. It refers to all aspects of
the process—from identifying problems to be solved or
opportunities to be exploited to the implementation and
refinement of the chosen solution.
2.
Which of the following people ultimately benefit from a
systems development project?
a.
computer programmers
11. What consists of all activities that, if delayed, would delay
the entire project?
a.
b.
systems analysts
c.
stakeholders
deadline activities
d.
senior-level manager
b.
slack activities
3.
_______________ requires unbiased and careful ques-
tioning of whether systems elements are related in the most
effective or efficient ways.
c.
RAD tasks
d.
the critical path
4.
Like a contractor constructing a new building or renovating
an existing one, the programmer takes the plans from the
systems analyst and builds or modifies the necessary soft-
ware. True or False?
Systems development starts with investigation and analysis of
existing systems.
12. The systems request form is a document that is filled out
during systems analysis. True or False?
5.
The term
__________________
refers to the translation
of strategic and organizational goals into systems develop-
ment initiatives.
13. Feasibility analysis is typically done during which systems
development stage?
a. investigation
b. analysis
c. design
d. implementation
14. Data modeling is most often accomplished through the use
of _______________, whereas activity modeling is often
accomplished through the use of _________________.
15. The overall purpose of requirements analysis is to deter-
mine user, stakeholder, and organizational needs. True or
False?
6.
What involves investigating new approaches to existing
problems?
a.
critical success factors
b.
systems analysis factors
c.
creative analysis
d.
critical analysis
Systems development often uses tools to select, implement,
and monitor projects, including net present value (NPV),
prototyping, rapid application development, CASE tools, and
object-oriented development.
