Q211.
What is the main aim of developing a software prototype?

a.

To test the usability of the proposed system

b.

To test the speed and robustness of the proposed system

c.

To test the functionality of the proposed system

d.

All of the above

Discuss
Answer: (a).To test the usability of the proposed system Explanation:The main aim of developing a software prototype is to test the usability of the proposed system. It allows for the development of a working model of the software system that emphasizes certain aspects, such as usability.
Q212.
What is the main difference between the development of software and the development of physical products?

a.

The highest costs are incurred during production for physical products, but not for software

b.

Software development requires more prototypes than physical product development

c.

Software development is more expensive than physical product development

d.

Physical product development requires more testing than software development

Discuss
Answer: (a).The highest costs are incurred during production for physical products, but not for software Explanation:The main difference between the development of software and the development of physical products is that in developing physical products, the highest costs are generally incurred during production, when multiple copies of the product are being produced, while in software development, making multiple copies of the product is almost free.
Q213.
What are some ways to develop a software prototype relatively cheaply?

a.

Use of very high-level languages

b.

Development of a system with less functionality

c.

Use of low-level languages

d.

Development of a system with more functionality

Discuss
Answer: (a).Use of very high-level languages Explanation:To develop a software prototype relatively cheaply, one can use very high-level languages in which an executable version can be created quickly, and develop a system with less functionality, in particular as regards quality attributes such as speed and robustness.
Q214.
What is the main goal of prototyping in software development?

a.

To deliver a first version of the system to the user

b.

To clarify requirements for the prospective user

c.

To assess the correctness of the transition to the next phase

d.

To increase the understanding of the software process

Discuss
Answer: (b).To clarify requirements for the prospective user Explanation:Prototyping is a tool used in software development to help users express their requirements more precisely. It is achieved by developing the user interface quickly, allowing the prospective user to work with a system that contains the interaction component but not the software that actually processes the input. This helps the user get a good impression of what the future system will provide, before large investments are made to realize the system.
Q215.
What is the main difference between throwaway prototyping and evolutionary prototyping?

a.

Throwaway prototyping involves discarding the software product after the prototyping phase while evolutionary prototyping involves evolving the prototype to the final product

b.

Throwaway prototyping involves using different techniques and tools during the actual production phase while evolutionary prototyping does not

c.

Throwaway prototyping emphasizes more on documentation while evolutionary prototyping does not

d.

Throwaway prototyping is used more often than evolutionary prototyping

Discuss
Answer: (a).Throwaway prototyping involves discarding the software product after the prototyping phase while evolutionary prototyping involves evolving the prototype to the final product Explanation:Throwaway prototyping involves discarding the software product after the prototyping phase is over, while evolutionary prototyping involves iterating through the user-validation process and evolving the prototype to the final product. In practice, evolutionary prototyping is used more often than throwaway prototyping as discarding a (partly) working system is a hurdle that is not easily taken.
Q216.
What is the main goal of Agile methods?

a.

To deliver a first version of the system to the user

b.

To clarify requirements for the prospective user

c.

To deliver value to the customer as quickly as possible

d.

To increase the understanding of the software process

Discuss
Answer: (c).To deliver value to the customer as quickly as possible Explanation:Agile methods view the world as fundamentally chaotic and assume that change is inevitable. Their focus is to deliver value to the customer as quickly as possible.
Q217.
What are the advantages of a prototyping approach?

a.

The resulting system is easier to use

b.

User needs are better accommodated

c.

The resulting system has fewer features

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:The advantages of a prototyping approach include that the resulting system is easier to use, user needs are better accommodated, and the resulting system has fewer features.
Q218.
What are the disadvantages of a prototyping approach?

a.

The resulting system has more features

b.

The performance of the resulting system is worse

c.

The design is of lesser quality

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:The disadvantages of a prototyping approach include that the resulting system has more features, the performance of the resulting system is worse, and the design is of lesser quality.
Q219.
What are the benefits of involving users in the development process through prototyping?

a.

Users feel more involved in the development process

b.

Fewer conflicts with the designers

c.

The resulting system better satisfies user needs

d.

All of the above

Discuss
Answer: (d).All of the above Explanation:The benefits of involving users in the development process through prototyping include that users feel more involved in the development process, there are fewer conflicts with the designers, and the resulting system better satisfies user needs.
Q220.
What is prototyping in software development?

a.

A method of developing software using detailed plans and processes

b.

A method of developing software using a working model of the system to test usability

c.

A method of developing software using a heavy-weight development method

d.

A method of developing software using agile methods

Discuss
Answer: (b).A method of developing software using a working model of the system to test usability Explanation:Prototyping in software development is a method where a working model of the system is developed to test the usability of the proposed system before large investments are made to realize the system.
