Learning objectives

1) List and discuss the purpose and use of

systems flowcharts, document flowcharts, program flowcharts, and hardware

flowcharts

2) Explain the basic parts of and design

considerations common to all types of

flowcharts

3) Identify and describe common symbols

and information technology tools used in flowcharting

4) Discuss ways flowcharts impact the

design, implementation, and evaluation of accounting information systems

5) Create and interpret systems flowcharts

Trang 4

Flowchart types & uses in AIS

• Systems flowcharts

– Provide a “big

picture” overview of

a system

– Often used in AIS

to understand

business

processes

• Document flowcharts

– Track the flow of documents through

an information system

– Sometimes used in AIS to check &

improve document processing

– Documents include

Trang 5

Flowchart types & uses in AIS

• Hardware

flowcharts

– Show the

relationships

between hardware

elements of an

information system

– Occasionally used

in AIS to

understand

network

components

internal control

changing network configuration

• Program flowcharts

– Show the logic associated with a computer program

– Almost never used

in AIS

Trang 6

Symbols

• Four groups

Symbols for databases and documents

– Process

Design considerations

• Flowcharting is at least as much “art” as

“science.”

• Independently drawn flowcharts of the

same process will almost never be

identical

• The goal is to produce a flowchart that is

concise and understandable—not to

reproduce someone else’s work

Trang 12

Design considerations

• Title

• One start, one end

• Columns based on

areas of

responsibility

• Plenty of white space

• Top to bottom, left

to right (in general)

• Clear origin and termination for all documents

Trang 13

Design steps

1) Establish the

system boundary

2) Determine column

headings

3) List actions

performed within

each column

4) Select appropriate

symbols

5) Prepare a first

draft

6) Discuss the draft

with others

7) Revise as

needed
