Q221.
What is throwaway prototyping?

a.

A method of developing software where the prototype is discarded after the prototyping phase

b.

A method of developing software where the prototype is evolved to the final product

c.

A method of developing software using detailed plans and processes

d.

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

Discuss
Answer: (a).A method of developing software where the prototype is discarded after the prototyping phase Explanation:Throwaway prototyping is a method where the prototype is discarded after the prototyping phase, and a new system is developed with the gathered requirements.
Q222.
What is evolutionary prototyping?

a.

A method of developing software where the prototype is discarded after the prototyping phase

b.

A method of developing software where the prototype is evolved to the final product

c.

A method of developing software using detailed plans and processes

d.

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

Discuss
Answer: (b).A method of developing software where the prototype is evolved to the final product Explanation:Evolutionary prototyping is a method where the prototype is evolved to the final product through a series of iterations where new or changed requirements trigger the next cycle.
Q223.
What are the advantages of prototyping?

a.

The resulting system is harder to use

b.

User needs are not well accommodated

c.

The resulting system has fewer features

d.

The development incurs more effort

Discuss
Answer: (c).The resulting system has fewer features Explanation:Advantages of prototyping include that the resulting system has fewer features, user needs are better accommodated, problems are detected earlier and the development incurs less effort.
Q224.
What are the disadvantages of prototyping?

a.

The resulting system is easier to use

b.

The resulting system has more features

c.

The development incurs less effort

d.

Both b and c

Discuss
Answer: (d).Both b and c Explanation:Disadvantages of prototyping include that the resulting system has more features, the performance of the resulting system is worse, the design is of lesser quality, and the development incurs more effort.
Q225.
When is prototyping particularly useful?

a.

When the user requirements are clear and well defined

b.

When the system has a considerable emphasis on the user interface and high degree of user interaction

c.

When the development team is inexperienced

d.

When the system has a high performance requirements

Discuss
Answer: (b).When the system has a considerable emphasis on the user interface and high degree of user interaction Explanation:Prototyping is particularly useful for systems with a considerable emphasis on the user interface and which show a high degree of user interaction, as it allows to quickly create a working model of the system to test and verify the usability of the proposed system.
Q226.
What is incremental development?

a.

A method of building software in which the final system is the last of a series of prototypes

b.

A method of building software in which the functionality of the system is produced and delivered to the customer in small increments

c.

A method of building software in which the user is closely involved in planning the next step

d.

A method of building software in which the "overfunctionality" syndrome is avoided

Discuss
Answer: (b).A method of building software in which the functionality of the system is produced and delivered to the customer in small increments Explanation:Incremental development is a method of building software in which the functionality of the system is produced and delivered to the customer in small increments, starting from the existing situation and proceeding towards the desired situation in a number of small steps. This method is used to avoid the "Big Bang" effect and to fight the "overfunctionality" syndrome.
Q227.
What is the main difficulty faced by users in expressing their requirements precisely?

a.

Difficulty in understanding the technology

b.

Difficulty in understanding the process

c.

Difficulty in understanding the requirements

d.

Difficulty in understanding the system

Discuss
Answer: (c).Difficulty in understanding the requirements Explanation:The main difficulty faced by users in expressing their requirements precisely is their difficulty in understanding their own requirements.
Q228.
Why are prototypes useful in software development?

a.

To test the usability of the proposed system

b.

To test the functionality of the proposed system

c.

To test the performance of the proposed system

d.

To test the robustness of the proposed system

Discuss
Answer: (a).To test the usability of the proposed system Explanation:Prototypes are useful in software development as they allow users to test the usability of the proposed system before large investments are made to realize the system.
Q229.
What is the main advantage of incremental development approach?

a.

Avoiding the 'Big Bang' effect

b.

Improving the design quality

c.

Reducing the development effort

d.

Increasing the robustness of the system

Discuss
Answer: (a).Avoiding the 'Big Bang' effect Explanation:The main advantage of incremental development approach is that it avoids the 'Big Bang' effect by producing and delivering the functionality of the system in small increments, allowing for a more gradual and manageable transition to the final system.
Q230.
What is the spiral model of software development process proposed by Boehm?

a.

A model in which the final system is the last of a series of prototypes

b.

A model in which the development process is completed in one large step

c.

A model in which the development process is completed in a series of small steps

d.

A model in which the development process is completed in a spiral

Discuss
Answer: (d).A model in which the development process is completed in a spiral Explanation:The spiral model of software development process proposed by Boehm is a model in which the development process is completed in a series of small steps, where each convolution of the spiral focuses on identifying and solving the sub-problem with the highest associated risk.
