Question 1
In Object-Oriented Programming, an object is kind of person, place, event, or
thing about which we want to capture.
1 / 1 point
True
False
Correct
An object is an instantiation of a class. Refer to 4.1-1: Object Orientation for
more information.
2.
Question 2
An application for a fast food chain models each user with a class. Any user
can apply a 5% off coupon code when ordering a meal above $10 (represented
by a class labelled User), however users that pay a monthly fee can also apply
a 10% off coupon code when ordering any menu item from the store and are
represented by a subclass of User labeled specialUser. Is this an example of
inheritance?
1 / 1 point
Yes
No
Correct
SpecialClass inherits the same method from User, which is by definition
inheritance. Refer to 4.1-2: Inheritance and UML for more information.
3.
Question 3
Which of the following is false?
1 / 1 point
It is usually much easier to restructure a UML diagram than restructure code.
In a sequence diagram, the program is represented visually by an ‘actor’ that sends ‘messages’ to
the objects throughout the time of the interaction.
In a state machine diagram, various states of an object in a program are represented by arrows
throughout the diagram.
Correct
States are represented by boxes, while the transitions from one state to
another are represented by arrows. Refer to 4.1-3 Additional UML Diagrams
for more information.
4.
Question 4
Which of the following is true about acquisition strategies?
1 / 1 point
If a firm does not fully understand how to develop or implement a software system, it is often more
effective to outsource that system to a vendor.
In the long run, it is usually more cost-effective to develop new software in-house.
One of the drawbacks to outsourcing software development is that it is harder to control the quality
of the design and ensure that it meets the necessary requirements.
Correct
Outsourcing the problem means that there is less assurance that the product
will be met with the same regard for quality and time efficiency. Refer to 4.2-1
Acquisition Strategies for more information.
5.
Question 5
Which is the best way to describe an Alternative Matrix?
1 / 1 point
Since it considers every technical criteria for a system with a corresponding weight, the resulting
scores of an Alternative Matrix for a given system determine which alternative is objectively the best
decision for the firm to make as it is comprehensive of every factor going into that system’s
development.
The scores of an Alternative Matrix should only be considered as a factor in the decision-making
process for a firm, and should be weighed against other external criteria by an experienced leader
responsible for the system’s development.
Correct
The matrix does not consider external factors (such as money, time factors)
and thus should not be the only factor to consider in making the development
decision. Refer to 4.2-2 Alternative Analysis for more information.
6.
Question 6
Online retailers frequently implement systems that recommend other
products to customers based on their previous purchase history, what time of
year they made the purchase, what other customers frequently bought in
addition to the customers purchase, and other data relating to the purchase.
This is an example of:
1 / 1 point
Business Intelligence Architecture
Operational Architecture
Correct
Recall the example of Wal-Mart stocking pop tarts before Hurricane Ivan.
Utilizing data to make decisions and predictions is Business Intelligence.
Refer to 4.2-3 Architectural Options for more information.
7.
Question 7
The best implementation might be a human implementation of a physical
process.
1 / 1 point
True
False
Correct
Although systems are mostly used as physical process implementations, there
may exist scenarios in which a human implementation is best. Refer to 4.3-1
Design Logical to Physical for more information.
8.
Question 8
Which of the following is the definition of “scope creep”?
1 / 1 point
When ERP management locks a firm into one ecosystem, resulting in all data being managed under
the same vendor.
When additional features are requested during the implementation phase of a project, thus
increasing the cost and time required to complete said project.
Correct
Managing scope creep is the largest responsibility of the Project Manager
during the implementation phase. Refer to video 4.3-2 Develop Test Document
for more information.
9.
Question 9
The Business Analyst is involved with preparing the technology during the
migration plan.
1 / 1 point
True
False
Correct
The Business Analyst focuses on preparing the business and preparing the
people during the migration plan. Review video 4.4-1 Transition for more
information.
10.
Question 10
The Maintenance phase in the SDLC described in this course is the longest
and costliest phase.
1 / 1 point
True
False
Correct
Although not included in the SDLC described in this course, this phase occurs
after the implementation phase but is equally important because it may last
the lifetime of the product and is where the majority of the total cost of the
system comes from through tasks like project assessment, system support,
and system maintenance. Review video 4.4-2 Maintenance and Total Cost of
Ownership for more information.
