Question 22

These are statements that describe what the system should do or possess to meet the needs of its users and stakeholders.

Answer 22

System Requirements

Question 23

These requirements define the attributes and qualities that describe how the system should perform, rather than what it should do.

Answer 23

Non-functional Requirements

Question 24

These requirements define what the system should do. They define what the system should achieve in terms of features and capabilities.

Answer 24

Functional Requirements

Question 25

This is the third stage which includes beginning to meet the system requirements. It includes output and user interface design, data design, and system architecture.

Answer 25

Systems Design

Question 26

This is the method by which a prototype is developed. It involves a repetitive sequence of analysis, design, modeling, and testing.

Answer 26

Prototyping

Question 27

This prototyping methods produces a full-featured, working model of the information system. Because the model is “on track” for implementation, it is especially important to obtain user feedback, and to be sure that the prototype meets all requirements of users and management.

Answer 27

System Prototyping

Question 28

This prototyping method is a method of development that employs technical mechanisms for reducing risk in a project, when the project needs are vaguely and poorly laid out.

Answer 28

Design Prototyping or Throwaway Prototyping
