When the business need is unique and the process is critical to the business, the most
appropriate development strategy is packaged software.
The project manager is the person who wants the change that a new system brings in an
organization.
In order for managers to receive all the information needed to support the task for
which it was designed, the report should provide all the information available on the
subject and allow the managers to select that which they wish to use.
Since a Manager has a higher position than an Employee, it is a good idea to design
class Manager as a superclass, and the class Employee inherits class Manager.
Client-server architectures strive to balance the processing between the client and the
server by having both perform some of the application functions.
The analysis phase of the SDLC ends when a system proposal for the new system is
presented to the approval committee.
A rectangle with rounded corners is used to represent an initial state on a behavioral
state diagram.
Association relationships are used for the relationship between instances of two classes
when the relationship is not specific enough to be considered a generalization or an
aggregation relationship.
Agile development methodology aims at eliminating the modeling and documentation
overhead in IS projects, while emphasizing simple, iterative application development.
A pre-condition is a constraint that must be met after the method executes.
The interface standard that describes the general appearance of all the screens in the
information system and the paper-based forms and reports that are used/developed by
the system is the interface templates.
There are several techniques that the project team can use to try to speed up access to
the data: denormalization, clustering, and indexing.
System analysts use structural models to depict the internal structural or static view of
an information system.
Familiarity with the application and technology are major factors considered under
economic feasibility.
Legacy databases and systems are one of seven factors in the hardware and software
specification document
Subclasses inherit the appropriate attributes and methods from the superclass above
them.
A classic mistake made during the implementation phase is to coordinate changes to the
source code, since that increases the development time.
In a behavioral state diagram, an action is non-atomic in nature while an activity is
atomic and cannot be interrupted.
Economic feasibility is determined by identifying costs and benefits associated with the
system, assigning values to them, and then calculating the cash flow and return on
investment for the project.
A whole-system conversion, in which the entire system is installed at one time, is the
least common because it is complex and the hardest to understand.
Adding staff to a project to shorten the project’s length is usually a wise move, because
adding staff normally translates into increased productivity.
If a class represents only temporary objects, then there should be a D in the column of
the CRUD matrix.
Parallel conversion is less risky than direct conversion because it has a greater chance
of detecting bugs that have gone undiscovered in testing; pilot conversion is less risky
than either phased or simultaneous conversion because if bugs do occur, they occur in
only pilot test locations.
Activity-based costing is similar to duration analysis. While duration analysis attempts
to find the time taken to complete business processes, activity-based costing finds the
costs associated with each of the basic functional steps or processes.
CASE tool is a popular graphic depiction of the work plan that lists project tasks along
a y-axis, time along an x-axis, and uses shaded boxes to represent tasks.
Cost benefit analysis identifies the financial costs and benefits associated with a
systems project.
Jim Smith is a project manager in the IS department of an insurance company and he
just hired a group of four contractors to work on a project together with an in-house
team of 4 full-time employees. He should use extreme programming as a methodology
for the project.
Gamification deals with applying gaming mechanics to gaming business..
A reference document describes how to perform a business task that typically requires
several computer functions or steps.
It is easier to ask an interviewee what is used to perform a task than it is to show the
interviewee a form and ask what information on the form is used.
Many project teams believe that packaged software is the best way to create a system
because they have complete control over the way the system looks and functions, and
they can be flexible and creative in the way they solve business problems.
Lauren and her team have been hired to create a transaction system for Mike’s
Motorcycles. Mike’s is a medium size shop with 10 employees that sells motorcycle
parts and does repair on motorcycles, lawn mowers, and other small engine systems
(boats, dune buggies, tractors, etc.) As part of Lauren’s team, you need to recommend
relational database management system.
The function that provides the logic related to the problem domain layer is called
application logic.
Benefits to using computer-aided software engineering (CASE) include faster task
completion and alteration, centralized development information, and illustration of
information through diagrams.
Comparing managing programmers in a feminine culture than in a masculine culture, it
is more important to ensure that the workplace is a supportive, non-competitive, and
nurturing environment in a feminine culture.
Determining whether the new system will be compatible with the existing technology
that already exists in the organization is part of the organizational feasibility study.
Extreme programming is ideal for developing large mission-critical applications.
In order to verifying and validating class and method design, all constraints, contracts,
and method specifications must be tested.
One of the criticisms of the Unified Process is that if fails to deal with the system after
it has been delivered.
What is connascence? Is this desirable or undesirable in a system? Why?
Institutionalization refers to using the new system as the normal, accepted, and routine
way of performing the business processes.
During an interview, the analyst has been asking about the process used to identify and
correct the number of poor-quality products produced on a manufacturing line.
The analyst commented, “This process seems way too slow and complicated. I don’t
know how you people can function if this is the way things are done.” Is this an
appropriate comment for the interviewer to make? Why or why not?
Explain the “Conversion Location” dimension and its impact on the conversion process.
Briefly describe the idea behind the RAD approach to systems development.
What are the three fundamental analysis strategies? Compare and contrast the outcomes
of each strategy.
Describe communication diagrams.
Briefly describe the Story Cards and Task Lists requirements documentation
techniques. What are some of the advantages of using story cards and task lists as a
requirements gathering and documentation technique?
Discuss the tests performed during system testing.
Briefly discuss the procedure for verifying and validating class and method design.
Discuss the problem of bias with regard to graphical outputs.
