Q

This flowchart illustrates the flow documents and information between areas of responsibility within an organization.

A

Document flowchart

20
Q

This type of flowchart depicts the relationship among the input, processing, and output of an AIS.

A

System flowchart

21
Q

This flowchart describes the specific logic to perform a process shown on a systems flowchart.

A

Program flowchat

22
Q

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

A

System Requirements

23
Q

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

A

Non-functional Requirements

24
Q

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

A

Functional Requirements

25
Q

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.

A

Systems Design

26
Q

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

A

Prototyping

27
Q

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.

A

System Prototyping

28
Q

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.

A

Design Prototyping or Throwaway Prototyping

29
Q

What does CASE stand for?

A

Computer-aided Systems Engineering

30
Q

This is a tool that supports the rapid development of computer programs
by translating a logical model directly into code. Also called a code generator.

A

Application generators

31
Q

This is a computer program whose purpose is to take data from a source such
as a database, XML stream or a spreadsheet, and use it to produce a document in a format
which satisfies a particular human readership

A

Report Generators

32
Q

This is also called a form painter, it is an interactive tool that helps you design a custom
interface, create screens forms, and handle data entry format and procedures.

A

Screen Generators

33
Q

This is a functioning system, but it is less efficient than a fully developed system

A

Prototype

34
Q

This describes how users interact with a computer system, and consists of all the hardware,
software, screens, menus, functions, output, and features that affect two-way communications
between the user and the computer.

A

User Interface

35
Q

This uses visual objects and techniques that allow users to communicate
effectively with the system.

A

Graphical User Interface

36
Q

These allow users to send commands to the system.

A

Process-controlled Systems

37
Q

These are about how users communicate with the information system, and how
the system supports the firm’s business operations

A

User-centered Systems

38
Q

This describes the relationship between computers and people who use
them to perform their jobs

A

Human-Computer Interaction

39
Q

This phase begins once the client has tested and approved the system.
The system is installed at this phase to support the specified business functions.

A

Systems Implementation

40
Q

This is a continuous operation that includes eliminating
program and design flaws, updating documentation and test data, and updating user support.

A

Systems Maintenance
