|
1.
|
Increasingly, organizations adopt and follow a
standardized systems development process.
|
|
|
2.
|
Most information systems meet expectations and come
in within budget.
|
|
|
3.
|
Organizations that develop software for the U.S.
government must adhere to certain quality management requirements.
|
|
|
4.
|
The first principle of a systems development
methodology is to get the system owners and system users involved.
|
|
|
5.
|
Some organizations develop their own system
development methodologies.
|
|
|
6.
|
A problem could be a real problem, an opportunity
for improvement or a directive from management.
|
|
|
7.
|
Project management ensures that an information
system is developed at minimum cost, within a specific time frame, and with acceptable
quality.
|
|
|
8.
|
Cost effectiveness is the result obtained by
striking a balance between the lifetime costs of developing, maintaining, and operating an
information system and the benefits derived from the system.
|
|
|
9.
|
A feasibility study is done to determine if a
system development project is cost-effective. After that point, the project will not be
cancelled.
|
|
|
10.
|
The first solution an analyst finds is usually the
best solution. It is not cost effective to consider alternatives.
|
|
|
11.
|
By dividing a larger problem (system) into more
easily manage pieces (subsystems); the analyst can simplify the problem-solving
process.
|
|
|
12.
|
According to best practices, it is important to
consider the information system as a whole if one is going to get the best solution. Dividing it into
smaller pieces is an obsolete way to design and develop the system.
|
|
|
13.
|
Information systems should be designed for growth
and change. Where possible, flexibility and adaptability are important to the overall success and
longevity of an information system.
|
|
|
14.
|
The sole focus of system development should be to
meet today's user requirements. It is impossible to anticipate ways to meet future needs since
they are unknown. It is better to develop the system as quickly as possible with the requirements
that are known today.
|
|
|
15.
|
Problems are undesirable situations that prevent
the organization from fully achieving its purpose, goals and/or objectives.
|
|
|
16.
|
A directive is a new requirement that's
imposed by management, government or some external influence.
|
|
|
17.
|
FAST is a leading commercial
methodology.
|
|
|
18.
|
Projects are always planned.
|
|
|
19.
|
A steering committee is comprised of system owners
and IT managers who determine which requests and projects get approved and scheduled.
|
|
|
20.
|
The scope definition phase must consider the
question, "Is this project worth looking at?"
|
|
|
21.
|
Scope frequently changes during a
project.
|
|
|
22.
|
Scope defines how big the project is or will
be.
|
|
|
23.
|
Given the initial scope of the project, the analyst
can staff the project team, estimate the budget for systems development and prepare a schedule for
the remaining phases of development.
|
|
|
24.
|
The earliest that a systems analyst can project the
staffing for a project, estimate its budget and prepare a schedule is during the requirements
analysis phase.
|
|
|
25.
|
The problem analysis phase provides for a study and
analysis of the requirements for the new system.
|
|
|
26.
|
The primary deliverable of the problem analysis
phase is system improvement objectives. These objectives do not define inputs, outputs or processes.
Instead, they define the business criteria on which any new system will be evaluated.
|
|
|
27.
|
System designers and system builders can frequently
skip the requirements analysis phase because they have performed this step in the past and know what
the users need.
|
|
|
28.
|
Technical feasibility is used to determine if a
solution is technically feasible and if the staff has the technical expertise to design and build the
solution.
|
|
|
29.
|
Operational feasibility is used to determine if the
design team has the technical skills needed to actually get the proposed solution into
operation.
|
|
|
30.
|
Economic feasibility is used to determine if a
solution is cost-effective, which means that there is a favorable balance between the cost of
developing the solution and the benefits derived from that solution.
|
|
|
31.
|
Schedule feasibility is used to determine if the
performance of the proposed system will fit into the users' working schedules.
|
|
|
32.
|
Risk feasibility is the probability of a successful
implementation using the chosen technology and approach.
|
|
|
33.
|
A repository is a database or other filing
mechanism where system developers store all documentation, knowledge, and products for one or more
information systems or projects.
|
|
|
34.
|
Feasibility is a measure of how beneficial the
development of an information system would be to an organization.
|
|
|
35.
|
An iterative development methodology is often
called a waterfall development approach.
|
|
|
36.
|
A logical model does not include implementation
details.
|
|
|
37.
|
The sequential development approach has lost favor
with most system developers..
|
|
|
38.
|
Timeboxing is the imposition of a nonextendable
period of time, usually 6 to 9 days.
|
|
|
39.
|
Data modeling is a process-centered technique
popularized .by the structured analysis and design methodology.
|
|
|
40.
|
An advantage of the model-driven approach is that
it makes it easier to identify, conceptualize, and analyze alternative technical
solutions.
|
|
|
41.
|
Object-oriented analysis and design attempts to
merge the data and process concerns into singular constructs called objects. A system is documented
in terms of its objects and their interactions.
|
|
|
42.
|
Rapid application development (RAD) techniques
emphasize extensive user involvement for rapid and evolutionary construction of working prototypes of
a system to accelerate the system development process.
|
|
|
43.
|
Commercial off-the-shelf software is a software
package or solution that is purchased to support one or more business functions and information
systems.
|
|
|
44.
|
An enterprise resource planning (ERP) software
product is a fully integrated collection of information systems that span most basic business
functions required by a major corporation.
|
|
|
45.
|
Forward engineering allows a CASE tool to read
existing program code and transform that code into a representative system model that can be edited
and refined by the systems analyst.
|
|
|
46.
|
Reverse engineering requires the systems analyst to
draw system models, either from scratch or from templates. The resulting models are subsequently
transformed into program code.
