In-Depth Information
Systems review is the process of analyzing and monitoring
systems to make sure that they are operating as intended. The
two types of review procedures are the event-driven review
and the time-driven review. An event-driven review is trig-
gered by a problem or opportunity. A time-driven review is
started after a specified amount of time.
Systems review involves measuring how well the system
is supporting the mission and goals of the organization. Sys-
tem performance measurement monitors the system for
number of errors, amount of memory and processing time
required, and so on.
CHAPTER 13: SELF-ASSESSMENT TEST
Designing new systems or modifying existing ones should
always help an organization achieve its goals.
1.
10. What type of documentation is used by computer
operators to execute a program and by analysts and
programmers?
a. unit documentation
b. integrated documentation
c. technical documentation
d. user documentation
11. _________________ testing involves testing the entire
system of programs.
12. The phase-in approach to conversion involves running
both the old system and the new system for three months
or longer. True or False?
________________ details system outputs, inputs, and
user interfaces; specifies hardware, software, databases,
telecommunications, personnel, and procedures; and
shows how these components are related.
2.
Determining the hardware and software required for a new
system is an example of ____________.
a.
logical design
b.
physical design
c.
interactive design
d.
object-oriented design
3.
Disaster planning is an important part of designing security
and control systems. True or False?
Maintenance and review add to the useful life of a system but
can consume large amounts of resources. These activities can
benefit from the same rigorous methods and project manage-
ment techniques applied to systems development.
13. A(n) _______________ is a minor change to correct a
problem or make a small enhancement to a program or
system.
14. Many organizations require a request for maintenance
form to authorize modification of programs. True or False?
4.
________________ involves systems development efforts
that slash power consumption and require less physical
space.
5
Scenarios and sequence diagrams are used with
________________.
a.
object-oriented design
b.
point evaluation
c.
incremental design
d.
nominal evaluation
15. A systems review that is caused by a problem with an exist-
ing system is called ____________.
a. object review
b. structured review
c. event-driven review
d. critical factors review
16. Corporate mergers and acquisitions can be a reason for
systems maintenance. True or False?
17. Monitoring a system after it has been implemented is called
_________________.
6.
Near the end of the design stage, an organization prohibits
further changes in the design of the system. This is called
___________________.
7.
In object-oriented systems design, a sequence of events is
called a scenario and can be diagrammed in a sequence dia-
gram. True or False?
The primary emphasis of systems implementation is to make
sure that the right information is delivered to the right person
in the right format at the right time.
