INTRODUCTION
• Questions to be addressed in this chapter
include:
– What is the meaning of system, data, and
information
?
– What is an accounting information system (AIS)?
– Why is the AIS an important topic to study?
– What is the role of the AIS in the value chain?
– How does the AIS provide information for decision
making?
SYSTEMS, DATA, AND INFORMATION
• A system is:
– A set of interrelated components
– That interact

SYSTEMS, DATA, AND INFORMATION
• Every organization has goals.
– The subsystems should be designed to
maximize achievement of the organization’s
goals.
– Even to the detriment of the subsystem itself.
– EXAMPLE: The production department (a
subsystem) of a company might have to
forego its goal of staying within its budget in
order to meet the organization’s goal of
SYSTEMS, DATA, AND INFORMATION
•
Goal conflict occurs when the activity of a
subsystem is not consistent with another
subsystem or with the larger system.
•
Goal congruence occurs when the
subsystem’s goals are in line with the
organization’s goals.
• The larger and more complicated a

SYSTEMS, DATA, AND INFORMATION
• The
systems concept
encourages integration
(i.e., minimizing the duplication of recording,
storing, reporting, and processing).
•
Data
are facts that are collected, recorded,
stored, and processed by an information system.
• Organizations collect data about:
–
Events
that occur
SYSTEMS, DATA, AND INFORMATION
•
Information is different from data.
• Information is data that have been
organized and processed to provide
meaning to a user.
• Usually, more information and better
information translates into better

– External users
– Internal users
© 2008 Prentice Hall Business Publishing Accounting Information Systems, 11/e Romney/Steinbart 21 of 85
• Information is provided to both:
– External users
– Internal users
• External users primarily use information
that is either:
– MANDATORY INFORMATION—required by a
governmental entity, such as Form 10-K
required by the SEC; or
– ESSENTIAL INFORMATION—required to
conduct business with external parties, such
as purchase orders.
© 2008 Prentice Hall Business Publishing Accounting Information Systems, 11/e Romney/Steinbart 23 of 85
• In providing mandatory or essential
information, the focus should be on:
– Minimizing costs.
– Meeting regulatory requirements.
– Meeting minimum standards of reliability and
usefulness.
• Information is provided to both:
– External users
– Internal users
© 2008 Prentice Hall Business Publishing Accounting Information Systems, 11/e Romney/Steinbart 25 of 85
• Internal users primarily use discretionary
information.
• The primary focus in producing this
information is ensuring that benefits
exceed costs, i.e., the information has
positive value.
• An AIS is a system that collects, records,
stores, and processes data to produce
information for decision makers.
• It can:
– Use advanced technology; or
– Be a simple paper-and-pencil system; or
– Be something in between.
• Technology is simply a tool to create,
maintain, or improve a system.
© 2008 Prentice Hall Business Publishing Accounting Information Systems, 11/e Romney/Steinbart 27 of 85
• The functions of an AIS are to:
– Collect and store data about events,
resources, and agents.
– Transform that data into information that
management can use to make decisions
about events, resources, and agents.
– Provide adequate controls to ensure that the
entity’s resources (including data) are:
• Available when needed
• Accurate and reliable

WHY STUDY ACCOUNTING
INFORMATION SYSTEMS?
•
Accounting is an information-providing
activity, so accountants need to
understand:
–
How the system that provides that
information is designed, implemented,
and used.
–
How financial information is reported.

• Although “adding value” is a commonly used
buzzword, in its genuine sense, it means making
the value of the finished component greater than
the sum of its parts.
• It may mean:
– Making it faster
– Making it more reliable
– Providing better service or advice
– Providing something in limited supply (like O-negative
blood or rare gems)
– Providing enhanced features
– Customizing it
• Value is provided by performing a series of
activities referred to as the
value chain
.
These include:
– Primary activities
– Support activities
• These activities are sometimes referred to
as “line” and “staff” activities respectively.

be engaging in:
– Less structured decisions
– Broader scope (i.e., strategic planning)
decisions
• Corporations have:
– Unlimited opportunities to invest in
technology.
– Limited resources to invest in technology.
• Consequently, they must identify the
improvements likely to yield the highest
return.

• A product-differentiation strategy involves
setting your product apart from those of
your competitors, i.e., building a “better”
mousetrap by offering one that’s faster,
has enhanced features, etc.

• A low-cost strategy involves offering a
cheaper mousetrap than your competitors.
The low cost is made possible by
operating more efficiently.
• Sometimes a company can do both, but
they normally have to choose.

•
These strategic positions are not

• Choosing a strategic position is important
because it helps a company focus its efforts as
opposed to trying to be everything to everybody.
– EXAMPLE: A radio station that tries to play all types
of music will probably fail.
• It’s critical to design the organization’s activities
so they reinforce one another in achieving the
selected strategic position. The result is synergy,
which is difficult for competitors to imitate.
• The growth of the Internet has profoundly
affected the way value chain activities are
performed:
– Inbound and outbound logistics can be streamlined
for products that can be digitized, like books and
music.
– The Internet allows companies to cut costs, which
impacts strategy and strategic position.
– Because the Internet is available to everyone, intense
price competition can result. The outcome may be
that many companies shift from low-cost to
product-differentiation strategies.
– The Internet may impede access-based strategic

be closely integrated.
– The AIS should be the primary information
system to provide users with information they
need to perform their jobs.
