Question 3

As part of the bidding process required for bidding on providing a new software system to Kinect Incorporated,Thorton Wilder prepared a functional program that simulated the new system's input and output interface.This program is an example of
A)CASE.
B)an operational prototype.
C)a RFP.
D)a nonoperational prototype.

Accepted Answer

Thorton Wilder's functional program that simulated the new system's input and output interface is an example of an operational prototype. An operational prototype is a working model of the system or product that demonstrates its functionality and features. It is used to test and evaluate the system before finalizing it for production.

Question 4

Which statement below regarding prototyping is false?
A)Prototypes are considered "first drafts," which are quickly built and intended to be discarded when the real system is finished.
B)Developers who use prototyping still go through the systems development life cycle.
C)Prototypes help developers and end users make conceptual and physical design decisions.
D)Prototyping allows developers to condense and speed up parts of the analysis and design phases.

Accepted Answer

Prototypes are not necessarily intended to be discarded when the real system is finished. In some cases, the prototype itself may become the final system, with additional functionality and features added based on user feedback.

Question 5

Which of the following is an advantage of CASE?
A)It exhibits a high degree of cross-system compatibility.
B)It is an inexpensive technology that is accessible to small businesses.
C)Documentation is generated automatically.
D)It enhances the congruence between user expectations and the final system.

Accepted Answer

CASE generates documentation automatically, which saves time and reduces the risk of errors or omissions in documentation.

Question 6

As part of the bidding process required for bidding on providing a new software system to Kinect Incorporated,Thorton Wilder prepared diagrams that represent input and output screenshots.These diagrams are an example of
A)CASE.
B)an operational prototype.
C)a RFP.
D)a nonoperational prototype.

Accepted Answer

Diagrams representing input and output screenshots, which do not function but illustrate the design or concept, are examples of a nonoperational prototype. They are meant to show how the system will look or operate without having the actual functionality implemented.

Question 7

Which of the following were CASE tools not designed to do?
A)replace skilled designers
B)plan,analyze,design,program,and maintain an information system
C)automate important aspects of the software development process
D)enhance the efforts of managers in understanding information needs

Accepted Answer

CASE tools were not designed to replace skilled designers or developers but rather to enhance their work and automate important aspects of the software development process. They also help managers understand information needs and facilitate the planning, analysis, design, programming, and maintenance of an information system.

Question 8

Identify the system below where development would not likely benefit from treating a prototype.
A)decision support systems
B)executive information systems
C)expert systems
D)systems that cross a number of organizational boundaries

Accepted Answer

The answer of Identify the system below where development would...

Question 9

Which is not a problem with CASE technology?
A)cost
B)incompatibility
C)lack of system documentation
D)unmet expectations

Accepted Answer

Lack of system documentation is not a problem with CASE technology. CASE technology, or computer-aided software engineering, is designed to assist in the development and documentation of software systems. However, the cost of CASE tools and the potential for incompatibility between different tools and systems can be issues, along with the possibility of unmet expectations if the technology is not integrated and utilized effectively.

Question 10

Firms should consider preparing a software prototype if the application
A)will be used for a critical function like inventory management.
B)automates a structured task.
C)can be produced using outside developers.
D)inputs and outputs are not clearly defined.

Accepted Answer

Prototyping is particularly useful when the inputs and outputs of the application are not clearly defined. It allows for exploration and refinement of requirements through iterative development and feedback.

Question 11

The basic premise of ________ is that it is easier for people to express what they like or dislike about an existing system than to imagine what they would like in a system.
A)modified software
B)outsourcing agreements
C)prototyping
D)turnkey systems

Accepted Answer

This statement describes the basic premise of prototyping, which involves creating a mock-up or prototype of a system to solicit feedback from users before building the final product. By testing an existing system, users can more easily express their preferences or pain points than if they were asked to imagine what they'd like in an ideal system. Modified software, outsourcing agreements, and turnkey systems do not necessarily involve this premise.

Question 12

Firms should consider preparing a software prototype if the software
A)will be used for a critical function like accounts receivable.
B)automates an unstructured or semi-structured task.
C)can be produced using expertise available in-house.
D)is available as a canned package.

Accepted Answer

Prototyping is often recommended for software that automates unstructured or semi-structured tasks, especially if it involves complex user interactions. This is because it allows for early testing and iteration, which can help identify and address usability and functionality issues before significant time and resources are invested in development. Prototyping may not be necessary for software that automates more straightforward or well-understood tasks, can be readily purchased as a canned package, or can be developed in-house without significant uncertainty or risk. Accounts receivable software could be critical, but that factor alone wouldn't necessarily require a prototype.

Question 13

Which of the following is a one-time event that can yield dramatic performance improvements?
A)Business process reengineering (BPR)
B)Business process management (BPM)
C)Business process innovation (BPI)
D)Business process diagramming (BPD)

Accepted Answer

Business process reengineering (BPR) is a one-time event that involves a radical redesign of a company's core business processes to achieve dramatic improvements in performance, such as increased efficiency and faster delivery times. BPR is often used when a company is experiencing significant challenges or needs to make major changes to remain competitive. In contrast, BPM, BPI, and BPD are ongoing processes that involve continuous improvement and refinement of business processes over time.

Question 15

Identify a key advantage of a business process management system (BPMS)as compared to an event-based system.
A)ease of use
B)processing speed
C)cost
D)built in audit trail

Accepted Answer

The key advantage of a business process management system (BPMS) over an event-based system is the built-in audit trail. A BPMS provides a complete and transparent view of each step of the process, which enables easy monitoring, tracking, and analysis of activities in real-time thus providing a built-in audit trail functionality. This audit trail can improve compliance and transparency, making BPMS particularly suitable for industries where compliance is crucial, such as healthcare or finance.
