Question 1

What is the emphasis of the first step involved in developing a prototype?

Accepted Answer

The answer of What is the emphasis of the first...

Question 2

What is an advantage of prototyping?

Accepted Answer

Prototyping allows developers to create a working model of the system, which can be refined and updated based on user feedback, ensuring that the final system meets user needs effectively.

Question 3

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.

Accepted Answer

The basic premise of prototyping is that it allows users to share their feedback based on the prototype or an existing system. The idea behind prototyping is that it helps users identify the features that they like or dislike, making it easier to develop a final system that meets their needs. This is different from modified software, outsourcing agreements, and turnkey systems, which are all related to implementing or customizing existing systems rather than designing new ones.

Question 4

Business process reengineering (BPR)can be a challenging venture for all involved.Many reengineering efforts fail or fall short of the goals to be achieved in the process.Which statement below applies to the BPR obstacle of controls?

Accepted Answer

The answer of Business process reengineering (BPR)can be a challenging...

Question 5

A prototype that is turned into a fully functional system is referred to as a(n)

Accepted Answer

An operational prototype is a working model of a product or system that can be tested and evaluated to determine if it meets the requirements and specifications. It is an intermediate step between the initial concept and the final product, and is used to refine and improve the design before production. The other options, disappearing prototype, nonoperational prototype, and throwaway prototype, do not accurately describe a fully functional system.

Question 6

Computer-aided software (or systems)engineering is another tool used for improving the development process.What is one thing that CASE tools were not designed to do in assisting in the software and systems development process?

Accepted Answer

CASE tools were not designed to replace skilled designers. Although they automate many aspects of the software development process and enhance the efforts of managers in understanding information needs, they are still tools that supplement the work of skilled designers.

Question 7

Which of the following would not be considered a challenge when implementing business process reengineering efforts?

Accepted Answer

Availability of mainframe computer hardware and software is not typically a challenge when implementing business process reengineering efforts, as this is a technical issue that can generally be resolved through procurement or upgrades. The other options (cost, tradition, skepticism) are all common challenges that can arise during the implementation of business process reengineering efforts.

Question 8

There are four steps involved in developing a prototype.Which step emphasizes speed and low cost rather than efficiency of operation?

Accepted Answer

The second step involves creating a rough prototype that emphasizes speed and low cost rather than efficiency of operation. This prototype is often referred to as a "proof of concept" prototype and serves to test the basic functionality of the design concept. The other steps involve refining and improving the prototype for better performance and usability.

Question 9

Which statement below regarding prototyping is false?

Accepted Answer

The statement that a prototype is quickly and expensively built is false. Prototypes are generally built in a shorter time frame and are considered cost-effective compared to building a full-scale system.

Question 10

There are seven major principles of business process reengineering (BPR).One principle states that whenever possible,one person should be given responsibility for the entire process.What is the name given to this principle?

Accepted Answer

The principle that one person should be given responsibility for the entire process is known as "organize around outcomes, not tasks." This means that instead of breaking tasks up into separate departments or individuals, the focus should be on achieving the desired outcome by assigning a single individual or team to manage the entire process. This helps to streamline communication and decision-making, improve accountability, and increase overall efficiency.

Question 11

What factor underlies the seven principles of reengineering?

Accepted Answer

The seven principles of reengineering, which focus on the efficient and effective use of information technology, are based on the premise that technology can help organizations radically redesign their processes to achieve significant improvements in quality, cost, and service.

Question 12

One of the principles of business process reengineering is to centralize and disperse data.How is this principle defined?

Accepted Answer

The principle of centralizing and dispersing data in business process reengineering suggests that information technology can maintain a centralized database, while telecommunications technology can disperse data to necessary locations. This allows for efficient access to information while still allowing for necessary dispersal to different areas of the organization. Option A refers to integration at the end, option B refers to making data available but does not address centralization, and option C refers to eliminating job descriptions and departmental boundaries, which is not related to centralizing and dispersing data.

Question 13

Which is not a problem with CASE technology?

Accepted Answer

Lack of system documentation is not a problem with CASE technology. CASE (Computer-Aided Software Engineering) technology actually helps in creating system documentation, which is one of its advantages. The other options are potential problems with CASE technology.

Question 14

What is a disadvantage to prototyping?

Accepted Answer

The disadvantage of prototyping is that developers may become so focused on creating the prototype that they may shortchange the testing and documentation process. This can result in incomplete or inaccurate documentation, as well as overlooked bugs or other issues that may arise later in the development process.

Question 15

A sobering fact is that even though a trillion-plus-dollars has been spent on information technology in the last decade,productivity has not increased significantly.One change suggested to improve performance dramatically is to analyze thoroughly and completely redesign business processes and information systems.What is such a change called?

Accepted Answer

The change suggested, which involves analyzing and redesigning business processes and information systems, is called business process reengineering. Option A (CSC Index) is a consultancy firm and option C (end-user development) refers to creating software or applications by end-users rather than professional developers. Option D (information system outsourcing) involves engaging a third-party service provider to manage an organization's information systems.

Question 16

What is an advantage of using CASE?

Accepted Answer

Using CASE (Computer-Aided Software Engineering) tools simplifies documentation by automating the process and reducing the chances of human error. This makes it easier for developers to understand the software being designed and for clients to understand the requirements being documented. The other options (incompatibility, replacement of skilled designers, unmet expectations) are not advantages of using CASE.

Question 17

Developing and putting teams in charge of products is an application of which business process reengineering principle?

Accepted Answer

The answer of Developing and putting teams in charge of...

Question 18

CASE stands for

Accepted Answer

CASE can stand for both computer-aided software engineering and computer-aided systems engineering, and both are commonly used in the field of software development to help streamline the design and development process.

Question 19

What is a disadvantage of using CASE?

Accepted Answer

One of the main disadvantages of using CASE can be incompatibility with other tools or systems, which can limit its effectiveness and usefulness.

Question 20

The development of which type of system listed below would not benefit from the creation of a prototype?

Accepted Answer

Systems that cross a number of organizational boundaries may require a lot of time and resources to create a prototype and may involve collaboration with multiple stakeholders. However, decision support systems, executive information systems, and expert systems can benefit from the creation of a prototype as it allows stakeholders to provide feedback and make necessary adjustments before the final system is developed.
