what each module does.
Parallel development relies on only one iteration of the analysis phase.
An object is same as its class since both have attributes and behaviors.
Questionnaires are often used when there is only a small number of people from which
information and opinions are needed, because it is difficult to get a large number of
participants to return questionnaires on a timely basis.
CRUD matrices are created by creating a matrix that lists the classes across the top and
down the side.
A tool bar is a list of commands at the top of the screen that are always present on the
interface and may drop down immediately below another menu and disappear after one
use.
In the Enhanced Unified Process, the design and implementation workflows are the
primary focus of the production phase.
A use case that represents an important business process and involves the use of new
technology would likely be given an importance level of medium.
Contracts document the message passing that takes place between objects.
In the UML, the Use Case Diagram is an example of structure diagram.
Minicomputer typically costs hundreds of thousands of dollars while a mainframe costs
millions of dollars.

to the second normal form.
Under the Unified Process, the Project Management workflow includes risk
management and scope management, among several other activities.
Extreme programming is founded on core principles such as communication, simplicity,
feedback, and courage
Lauren, a systems analyst, has excellent interpersonal skills. To take advantage of her
skills, the functional lead of the project should assign her to program in Java and C++.

The four approaches to unit testing are user interface testing, use scenario testing, data
flow testing, and system interface testing; most projects use all four approaches.
Scalability is an important attribute in today’s systems. Client-server architectures tend
to be more scalable compared to the server-based architectures.
The traditional Work Breakdown Structure makes it easy to compare the current project
with past projects.
One of the guidelines for creating sequence diagram is: Place the initiator of the
scenario on the right of diagram.
Scott and Tim need to implement a very secure system for the Johnson Space Flight
Center. The Center has an endless hardware budget, so infrastructure costs are not a
consideration. The Center has a well trained IS staff that is available for the project.
Only six people will be interacting with the new system and they are engineers with
years of computer experience. Scott and Tim do not see changes to the system in the
near future.
Using the six characteristics of a computing architecture, make an architecture selection
recommendation to Scott and Tim.
What is a walkthrough?
Briefly describe the SCRUM agile development methodology.
Explain how the four fundamental computer application functions are handled in
client-server computing architectures. Discuss what is meant by fat client and thin client
configurations.
Describe how the concept of patterns in architecture relate to the development of
object-oriented systems. In what way do patterns promote reuse?
What are the six suggestions to address the mobile computing challenges?
When offshoring development, how could differences in Hall’s context dimension of
culture affect the contribution of a team member to the successful development of an
information system? What about Hall’s time or speed of messages dimensions?
Mariana, the IS manager, has just received a note from the accounting department
stating that they wish a new purchasing system could be placed on the priority list. The
chief accounting officer (CAO) has just learned that three of their competitors have new
purchasing systems. Since purchasing has not been considered a key business function
in the past, the CAO is concerned that his department lacks the functional expertise to
implement a new purchasing system. She feels that purchasing is becoming a strategic
necessity for the company and a new system should be in place by this time next year.
The CAO has managed the automation of numerous accounting functions, such as the
purchase of a combined general ledger with accounts receivable and accounts payable,
the custom development of a just-in-time inventory control system, and the
management of a financial projections and stock funds project that was contracted to an
outside vendor.

strategy selection process and the important characteristics that apply to the strategy
selected.
