Question 1

An advantage of prototyping is that creativity can increase because it allows for quicker user feedback, which can lead to better solutions.

Accepted Answer

Prototyping allows for iterative development and testing, enabling designers to quickly gather user feedback and make improvements, fostering creativity and innovation in finding effective solutions.

Question 2

A disadvantage of prototyping is that creativity can decrease because it allows for slower user feedback, which can lead to delayed solutions.

Accepted Answer

Prototyping typically allows for faster user feedback, which can enhance creativity and lead to quicker solutions.

Question 3

A disadvantage of prototyping is that it encourages a return to the "code, implement, and repair" life cycle that used to dominate information systems.

Accepted Answer

Prototyping can lead to a focus on quick fixes and iterative changes, which may result in a cycle of continuous coding and patching rather than thorough planning and design.

Question 4

An advantage of prototyping is that it encourages a return to the "code, implement, and repair" life cycle that used to dominate information systems.

Accepted Answer

Prototyping encourages iterative development and user feedback, which contrasts with the traditional "code, implement, and repair" approach by focusing on refining requirements and design before full-scale implementation.

Question 5

With prototyping there is no need for the systems analysis phases.

Accepted Answer

Prototyping is a part of the systems development process, but it does not eliminate the need for systems analysis phases, which are crucial for understanding requirements and designing a system that meets user needs.

Question 6

System design is also called logical design.

Accepted Answer

System design and logical design are related but distinct concepts. System design encompasses both logical and physical design, where logical design focuses on the abstract structure and relationships, while physical design deals with the actual implementation details.

Question 7

A disadvantage of prototyping is that you cannot completely substitute any prototype for a paper specification. No engineer would prototype an engine without some paper design. Yet many information systems professionals try to prototype without a specification. Prototyping should be used to complement, not replace, other methodologies. The level of detail required of the paper design may be reduced, but it is not eliminated.

Accepted Answer

Prototyping is meant to complement traditional design methods by providing a tangible model to test and refine ideas, but it cannot fully replace the detailed specifications needed for complex systems.

Question 8

Prototyping does not address numerous design issues. These issues can inadvertently be forgotten if you are not careful.

Accepted Answer

Prototyping can sometimes overlook certain design issues, especially if the focus is on rapid development and testing, leading to potential oversights if not carefully managed.

Question 9

Prototyping completely addresses design issues and helps you to remember all of them in detail.

Accepted Answer

Prototyping helps identify and address some design issues, but it may not catch all problems or ensure detailed recall of every issue.

Question 10

Prototyping is that it often leads to a premature commitment to a design (usually the first one implemented).

Accepted Answer

Prototyping can lead to premature commitment because stakeholders may become attached to the initial design, making it difficult to explore alternative solutions or improvements.

Question 11

A disadvantage of prototyping is that the scope and complexity of the system can quickly expand beyond original plans. This can easily get out of control.

Accepted Answer

Prototyping can lead to scope creep as stakeholders may continuously request changes and additions, leading to a more complex system than initially planned.

Question 12

Prototyping helps keep the scope and complexity of the system project under control.

Accepted Answer

The answer of Prototyping helps keep the scope and complexity...

Question 13

A disadvantage of prototyping is that it can reduce creativity in designs.

Accepted Answer

Prototyping can lead to a focus on the specific details of the design, which can limit the exploration of alternative ideas and reduce creativity.

Question 14

A disadvantage of prototypes is that they often suffer from slower performance than their third generation counterparts.

Accepted Answer

Prototypes are often initial versions of a product and may not be optimized for performance, unlike later, more refined versions.

Question 15

Prototypes can be built for simple outputs, computer dialogues, key functions, entire subsystems or even the entire system.

Accepted Answer

Prototypes can vary in scope and complexity, ranging from simple outputs to entire systems, depending on the purpose and requirements of the project.

Question 16

Prototypes can only be built to simulate the user dialogue with the system.

Accepted Answer

Prototypes can be built for various purposes, including simulating user dialogue, testing system functionality, evaluating design concepts, and gathering user feedback.

Question 17

Object technologies and techniques are an attempt to eliminate the separation of concerns about data and process.

Accepted Answer

Object technologies and techniques integrate data and processes by encapsulating them within objects, thus reducing the separation between data and the operations that manipulate them.

Question 18

Rapid application development (RAD) is the merger of various structured techniques (especially the data-driven information engineering) with prototyping techniques and joint application development techniques to accelerate systems development.

Accepted Answer

Rapid application development (RAD) combines structured techniques, prototyping, and joint application development to speed up the development process.

Question 19

Rapid application development calls for the interactive use of structured techniques and prototyping to define the users' requirements and design the final system.

Accepted Answer

Rapid application development (RAD) emphasizes quick development and iteration, using structured techniques and prototyping to refine user requirements and system design.

Question 20

Joint application development (JAD) is a technique that complements other systems analysis and design techniques by emphasizing participative development among system owners, users, designers and builders.

Accepted Answer

JAD is a collaborative approach that involves all stakeholders in the development process to ensure that the system meets the needs and requirements of all parties involved.
