System documentation is intended to help programmers and systems analysts
understand the application software and enable them to build it or maintain it after the
system is installed.
Michelle has been assigned the task of completing the project in a timely manner and
within budget. Her project team role is infrastructure analyst.
Class cohesion addresses the cohesion within each individual method of a class.
High levels of inheritance coupling in a system are always good and desirable.
Polymorphism means that the same message can be interpreted differently by different
classes of objects.
An analyst for an insurance company determined that the overall time required to
process a property damage insurance claim is 21 business days. When the analyst
decomposes the process into steps and aggregates the total time requirements for all
steps, she discovers a total time of 12 hours. The analyst is employing the activity-based
costing analysis technique.
Currently, there is only one major approach to support ubiquitous computing:
specialized computing devices.
An execution occurrence in a sequence diagram denotes when an object is sending or
receiving messages.
A post-condition is a constraint that must be met for a method to execute.
The champion is a high-level IS executive who initiates the system request and supports
the project by providing time, resources, and political support within the organization
by communicating the importance of the system to other organizational decision
makers.
Project team members focus on getting the project done, leaving change management to
the business managers.
If cost is a critical issue, you should assign the best, most expensive personnel to the
implementation phase; never assign entry-level personnel in an attempt to save costs.
A system proposal brings together into a SINGLE comprehensive document the
material created during planning and analysis..
A server in the server-based architecture performs application logic, data access logic,
data storage, and presentation logic.
An audit file contains information about how data changes over time; it records before
and after images of data as it is altered so that it can be validated later.
The goal of acceptance testing is to confirm that the system is complete, meets the
business needs that prompted the system to be developed, and is acceptable to the users.
Because of potential problems, developers must be aware of the effects of modifications
in a superclass and in each of the subclasses that will inherit the modification.
Performance testing typically falls into two categories: stress tests and speed tests.
A Case statement is an advanced form of an If statement.
The major problem with a server-based architecture is that all data on the server must
travel to the client for processing.
New programmers and systems analysts are typically assigned to work on complex new
development projects.
The data stores that are described as NoSQL typically support SQL.
The sponsor, the change agent, and the potential adopters are the actors found in the
change management process.
In a CRUD matrix, C represents Create.
Control flows in an activity diagram are shown using solid-lines with arrows while
object flows are shown using dashed lines with arrows.
Scott has been assigned to focus on the users during the upcoming information systems
installation. Scott will provide user training and documentation. His role is to serve as a
change management analyst.
It is possible for the multiplicity of a relationship to be “zero or more.”
On a behavioral state diagram, an arrow is used to represent a transition.
For urgent projects, it is a good idea to use a prototyping methodology.
Presentations outlining the costs and benefits of the new system do not motivate
potential adopters to use the new system, and should not be used as a motivating factor.
What process do we use to estimate systems development based on use cases?
Describe a formal process for evaluating a user interface.
Briefly summarize the purpose of the design phase in SDLC. Explain why it exists and
what it contributes to the completion of the system.
What is the primary goal of observation? What are three ways to make observation
more effective? How reliable are the results of observation?
Explain the consequences of a project manager allowing the scope of a project to
gradually increase. Why does ‘scope creep’ occur?
What are the methods used to identify improvement opportunities during business
process improvement? How do the methods used for each analysis strategy affect the
outcome of the “identify improvement” process?
Indicate the four phases of the waterfall approach and mention its advantages and
disadvantages.
Why is it necessary for an analyst to detail the specifications for the individual classes
and methods? What techniques are useful for doing this documentation?

_______ and object orientation.
a. functions
b. classes
c. objects
d. projects
e. use cases
Explain the terms event, action and activity.
What are the five optimizations that should be done to create a more efficient design?
Define what a structural model is. Why should a systems analyst create one? Why is the
creation of a structural model iterative?
Think of an employee object. What are several of the possible states that that object
may have over time? Which of these states would be the initial state? Which would be
the final state?
A local retailer has hired Geneva and Sydney to develop his new information system.
He is not sure what type of system he wants, but it must be completed in four months
and he needs to know regularly that the project is on schedule. Geneva and Sydney
should use the Waterfall Development methodology for constructing the system.
