It is difficult to find professionals with the necessary skill set for RDBMS.
Economic feasibility focuses on whether the system can be built by examining the risks
associated with the users’ and analysts’ familiarity with the application, familiarity with
the technology, and project size.
A highly effective motivational technique for technical staff is to provide recognition
for each team member’s accomplishments.
A value added contract provides for flexibility, but may result in a larger than expected
bill.
Estimates from the planning stage will need to be refined as the project progresses,
because it is virtually impossible to develop an exact assessment of the project’s
schedule before the analysis and design phases are conducted.
System users are stakeholders who perform hands-on activities related to the project.
The final step in the user interface design process, interface evaluation, usually does not
yield any improvements, because by that stage of the design process, all of the “bugs”
will normally have been removed from the system.
Project Management is a supporting workflow within the Unified Process.
The formula for net present value (NPV) is the ratio of (Total benefits ” Total Costs) to
Total Costs.
If you are interested in the time ordering of the messages in a system, you should use a
communication diagram.
Use cases are typically written to document the normal flow of events. Exceptions that
occur in the normal flow need not be documented as part of the use case description.
When drawing use case diagrams, higher level use cases are drawn below lower level
use cases.
A decision node in an activity diagram is used to represent the actual test condition that
is used to determine which of the paths exiting the node is to be traversed.
Kristin, a systems analyst, needs to know detailed information about the accounts
receivable process, but she is not concerned with accounts payable or general ledger, or
the integration of this information. Her analysis will assist her in designing a To-Be
system for the accounts receivable department. The appropriate requirements-gathering
technique to be used would be interviewing.
In order to prepare computer systems for global communication, discrete multilingual
systems contain separate parts that are written in multiple languages and must have
each language reinstalled before it can be used.
The general structure used in most on-line documentation for documents, procedures
manuals, or tutorials is called documentation items.
RFP, RFI and RFQ all could be used by project teams to collect information for making
acquisition decision.
Unit testing includes two kinds of tests: white box testing and black box testing.
A method that performs multiple functions that are unrelated to one another exhibits
Coincidental cohesion, and this type of cohesion is undesirable.
Using the word “client” repeatedly, instead of interchanging it with the word “customer”
is an example of the interface design principle for minimal user effort.
The Relational DBMS only supports simple data types, but the Object Relational
DBMS supports both simple and complex data types.
A key factor in staffing a project involves motivating people to meet the project’s
objectives, and the most effective way to do this is through the use of money and
bonuses.
There are only two different types of constraints typically captured in object-oriented
design: preconditions and postconditions.
A test plan is often a short document (1 to 2 pages) that has one to two sentences about
each test to be performed during the testing part of the implementation phase.
Coincidental is the worst type of method cohesion.
Dynamic binding refers to the ability of object-oriented systems to defer the data typing
of objects to run time.
The primary objective of the systems analyst is to create a wonderful system.
Benchmarking refers to studying how other organizations perform a business process so
you can learn how your organization can do it better.
Nicole has identified development and operational costs for a soon-to-be built
information system. Her findings will be listed under economic feasibility in the
analysis report.
The behavioral state diagram shows the different states that an object passes through in
response to events, together with its responses and actions.
Clicking a mouse can be an event.
What is coupling? Is this desirable or undesirable in a system? Why?
Define performance requirements. Briefly describe three key areas of performance
requirements.
What are the five characteristics of a use case that impacts its importance level?
Describe each, and indicate what conditions would result in a higher importance level.
If a project team wants to employ a conversion strategy that minimizes risk, what will
its choices be? What circumstances might dictate the use of the lowest risk conversion
strategy?
Describe the differences between an ORDBMS and an OODBMS, and list the
advantages of using an OODBMS over an OODBMS.
Describe the typical layout areas for a standard screen, a Web screen, and a report
screen.
Explain the distinction between user documentation and system documentation.
Explain the difference between normal flows and sub-flows that would be documented
in a use case.
Discuss four classic implementation mistakes, and how project teams can avoid these
mistakes.
Discuss three ways a system designer can improve the usability of the system’s reports?
Sara has been assigned by the project manager to serve as the testing manager for the
soon-to-be-completed systems project. The project manager has made it clear that this
systems project is normal in every way and they are to design a plan that would be
similar to the last. They have written a normal testing plan that is very similar to the
testing plan followed on the last three projects. What are the four stages of tests Sara
should include in their testing plan and what is the ideal type of test to be performed for
each stage.
Explain the syntax for drawing behavioral state diagrams.
Briefly describe three types of standards for system development, and provide examples
of each.
Kiki, the marketing manager, and Joan, the director of information systems, have just
returned from a conference on state-of-the art technology for marketing management.
Each day after viewing vendor presentations and listening to other marketing managers
discuss “what they don”t have and what they really need,” Kiki and Joan would brain
storm ideas and record them in Joan’s laptop. On the flight home, Joan, a successful
project manager, and Kiki, an experienced marketing professional, recognize that they
have the foundation for a one-of-a-kind marketing management system that would
improve the decisions the marketing staff must make. This new system could possibly
change the way their primary products are marketed. In the process, this new system
could save the company millions of dollars and possibly make millions more. Joan has
an expert IS staff that is just completing a production management system. They are
always interested in learning new technology and often request additional training. No
new projects have been approved by the steering committee.
What would you recommend Kiki and Joan do? Include in your discussion the design
strategy selection process and the important characteristics that apply to the strategy
selected.
Sara and Julian need to implement a system for the Johnson Space Flight Center. It is
projected that the Center will grow 60% or more over the next two years. These drastic
increases at the Center will be reflected in huge increases in personnel, the relocation of
offices, and many software upgrades. All of the software to be used in this system is
considered “non-secure”. The software will be purchased, thus reducing the cost of
development.
Using the six characteristics of a computing architecture, make an architecture selection
recommendation to Sara and Julian.

strategy for a project.
Explain the distinction between black box testing and white box testing.
What does the acronym CRUD stand for? Why would an analyst create a CRUD matrix
during his analysis?
