• In this chapter, we discuss two of the most common documentation tools:– Data flow diagrams– Flowcharts
• Include three types:– Document flowcharts describe the flow of documents and
information between departments or units.– System flowcharts describe the relationship between inputs,
processing, and outputs for a system.– Program flowcharts describe the sequence of logical
operations performed in a computer program.

INTRODUCTION TO DFD AND FLOWCHART
• Which method should you use—flowcharts or DVDs?– 62.5% of IS professionals use DFDs– 97.6% use flowcharts

DATA FLOW DIAGRAMS
• A data flow diagram (DFD) graphically describes the flow of data within an organization. It is used to:– Document existing systems– Plan and design new systems
• There is no black-and-white approach to developing a DFD.

FLOWCHARTS
• A flowchart is an analytical technique that describes some aspect of an information system in a clear, concise, and logical manner.
• Flowcharts use a set of standard symbols to depict processing procedures and the flow of data.
• Flowcharting History:– Introduced in 1950s by industrial engineers to document
business processes and document flows for process improvement.
– Sarbanes-Oxley 2002 increased importance by requiring companies to document business processes and internal controls procedures.

FLOWCHARTS
• Every shape on a flowchart depicts a unique operation, input, processing activity, or storage medium.
• In the days of yore, flowcharts were manually created using plastic templates.
• Most flowcharts are now drawn using a software program such as Visio.– Microsoft and Power Point are also used.– The software uses pre-drawn shapes, and the
developer drags the shapes into the drawing.

FLOWCHARTS
• There are four types of flowcharting symbols:– Input/output symbols
Input/output symbols indicate the type of device or media that provides input to or records output from a process.

DOCUMENT FLOWCHARTS
• A document flowchart shows the flow of documents and information among areas of responsibility in an organization.
• These flowcharts trace a document from cradle to grave and show:– Where a document comes from– Where it’s distributed– How it’s used– It’s ultimate disposition– Everything that happens as it flows through the
system
© 2008 Prentice Hall Business Publishing Accounting Information Systems, 11/e Romney/Steinbart43 of
119
DOCUMENT FLOWCHARTS
• Internal control flowcharts are document flowcharts used to evaluate the adequacy of internal controls, such as segregation of duties or internal checks.
• They can reveal weaknesses or inefficiencies such as:– Inadequate communication flows– Unnecessarily complex document flows– Procedures that cause wasteful delays
• Document flowcharts are also prepared in the system design process.

119
GUIDELINES FOR PREPARING FLOWCHARTS
• Let’s step through some guidelines for preparing flowcharts:– As with DFDs, you can’t effectively prepare a
flowchart if you don’t understand the system, so:• Interview users, developers, auditors, and
management• Administer questionnaires• Read through narratives• Walk through systems transactions
© 2008 Prentice Hall Business Publishing Accounting Information Systems, 11/e Romney/Steinbart45 of
119
GUIDELINES FOR PREPARING FLOWCHARTS
– Identify:• Entities to be flowcharted, e.g., departments,
functions, external parties (the parties who “do” things in the story)
• Documents or information flows• Processes
– As you read through a narrative, you may want to mark the preceding items with different shapes (e.g., drawing a rectangle around entities, circling documents, etc.).

This is part of the document flowchart from Figure 3-9 in your textbook.
© 2008 Prentice Hall Business Publishing Accounting Information Systems, 11/e Romney/Steinbart47 of
119
GUIDELINES FOR PREPARING FLOWCHARTS
–Use separate columns for the activity of each entity.• Example: If there are three different
departments or functions that “do” things in the narrative, there would be three columns on the flowchart.
© 2008 Prentice Hall Business Publishing Accounting Information Systems, 11/e Romney/Steinbart48 of
119
GUIDELINES FOR PREPARING FLOWCHARTS
– Flowchart the normal course of operations, and identify exceptions with annotations.
– As much as possible, the flow should go from top to bottom and left to right.
– Use standard flowcharting symbols, and draw with a template or computer.
– Clearly label all symbols. Use annotations if necessary to provide adequate explanation.
© 2008 Prentice Hall Business Publishing Accounting Information Systems, 11/e Romney/Steinbart49 of
119
GUIDELINES FOR PREPARING FLOWCHARTS
– Give the flowchart a clear beginning and ending.• Show where each document originated and its final
disposition.– One approach you can use is to read through
the narrative and for each step define:• What was (were) the input(s)• What process was carried out• What was (were) the output(s)
– Note on the next slide that the flow sequence is input—process—output.

GUIDELINES FOR PREPARING FLOWCHARTS
– Every manual process should have at least one input and at least one output.
– Show all data entered into or retrieved from a computer file as passing through a process first.
– Do not show process symbols for:• Forwarding a document to another entity• Filing a document

GUIDELINES FOR PREPARING FLOWCHARTS
– If a flowchart takes more than one page, label the pages as 1 of 5, 2 of 5, 3 of 5, etc.
– Show documents or reports first in the column where they are created.
– Start with a rough draft; then redesign to avoid clutter and crossed lines.
– Verify the accuracy of your flowchart by reviewing it with users, etc.
– Place the flowchart name, the date, and the preparer’s name on each page of the final copy.

The Revenue Cycle:
Sales to Cash Collections
© 2008 Prentice Hall Business Publishing Accounting Information Systems, 11/e Romney/Steinbart 73 of 161
INTRODUCTION
• In this chapter, we’ll look at:• Capturing and processing data.• Storing and organizing the data for decisions.• Providing controls to safeguard resources
(including data).
© 2008 Prentice Hall Business Publishing Accounting Information Systems, 11/e Romney/Steinbart 74 of 161
• The revenue cycle is a recurring set of business activities and related information processing operations associated with:– Providing goods and services to customers– Collecting their cash payments
• The primary external exchange of information is with customers.
© 2008 Prentice Hall Business Publishing Accounting Information Systems, 11/e Romney/Steinbart 75 of 161
– What are the basic business activities and data processing operations that are performed in the revenue cycle?
– What decisions need to be made in the revenue cycle, and what information is needed to make these decisions?
– What are the major threats in the revenue cycle and the controls related to those threats?
© 2008 Prentice Hall Business Publishing Accounting Information Systems, 11/e Romney/Steinbart 76 of 161
• Information about revenue cycle activities flows to other accounting cycles, e.g.:– The expenditure and production cycles
• Receive information about sales transactions so they’ll know when to initiate the purchase or production of more inventory.
© 2008 Prentice Hall Business Publishing Accounting Information Systems, 11/e Romney/Steinbart 77 of 161
• Information about revenue cycle activities flows to other accounting cycles, e.g.:– The expenditure and production cycles– The human resources/payroll cycle
• Uses information about sales to calculate commissions and bonuses.
© 2008 Prentice Hall Business Publishing Accounting Information Systems, 11/e Romney/Steinbart 78 of 161
• Information about revenue cycle activities flows to other accounting cycles, e.g.:– The expenditure and production cycles– The human resources/payroll cycle– The general ledger and reporting function
• Uses information produced by the revenue cycle in preparing financial statements and performance reports.

• The primary objective of the revenue cycle:– Provide the right product in the right place at
the right time for the right price.
© 2008 Prentice Hall Business Publishing Accounting Information Systems, 11/e Romney/Steinbart 81 of 161
• Decisions that must be made:– Should we customize products?– How much inventory should we carry and
where?– How should we deliver our product?– How should we price our product?– Should we give customers credit? If so, how
much and on what terms?– How can we process payments to maximize
cash flow?
© 2008 Prentice Hall Business Publishing Accounting Information Systems, 11/e Romney/Steinbart 82 of 161
• Management also has to evaluate the efficiency and effectiveness of revenue cycle processes:– Requires data about:
• Events that occur.• Resources used.• Agents who participate.
– The data needs to be accurate, reliable, and timely.
