Introduction

Welcome to Information Systems for Business and Beyond. In this book, you will be introduced to the concept of information systems, their use in business, and how information systems can be used to gain competitive advantage.

Audience

This book is written as an introductory text, meant for those with

little or no experience with computers or information systems.

While sometimes the descriptions can get a bit technical, every

effort has been made to convey the information essential to

understanding a topic while not getting overly focused in detailed

terminology.

Chapter Outline

The text is organized around thirteen chapters divided into three

major parts, as follows:

• Part 1: What Is an Information System?

◦ Chapter 1: What Is an Information System? – This chapter

provides an overview of information systems, including

the history of how information systems got to where it is

today.

systems hardware and how it works. You will look at

different computer parts and learn how they interact.

◦ Chapter 3: Software – Without software, hardware is

useless. This chapter covers software and the role it plays

in an organization.

◦ Chapter 4: Data and Databases – This chapter explores

how organizations use information systems to turn data

into information that can then be used for competitive

advantage. Special attention is paid to the role of

databases.

◦ Chapter 5: Networking and Communication – Today’s

computers are expected to also be communication

devices. This chapter reviews the history of networking,

how the Internet works, and the use of networks in

organizations today.

◦ Chapter 6: Information Systems Security – This chapter

discusses the information security triad of confidentiality,

integrity, and availability. Different security technologies

are reviewed, and the chapter concludes with a primer on

personal information security.

• Part 2: Information Systems for Strategic Advantage

◦ Chapter 7: Does IT Matter? – This chapter examines the

impact that information systems have on an organization.

Can IT give a company a competitive advantage? This

chapter discusses the seminal works by Brynjolfsson, Carr,

and Porter as they relate to IT and competitive advantage.

◦ Chapter 8: Business Processes – Business processes are the

essence of what a business does, and information systems

play an important role in making them work. This chapter

will discuss business process management, business

process reengineering, and ERP systems.

◦ Chapter 9: The People in Information Systems – This

chapter will provide an overview of the different types of

people involved in information systems. This includes

people who create information systems, those who

operate and administer information systems, those who

manage information systems, and those who use

information systems.

◦ Chapter 10: Information Systems Development – How are

information systems created? This chapter will review the

concept of programming, look at different methods of

software development, review website and mobile

application development, discuss end-user computing,

and look at the “build vs. buy” decision that many

companies face.

• Part 3: Information Systems beyond the Organization

◦ Chapter 11: Globalization and the Digital Divide – The rapid

rise of the Internet has made it easier than ever to do

business worldwide. This chapter will look at the impact

For the Student

Each chapter in this text begins with a list of the relevant learning

objectives and ends with a chapter summary. Following the

summary is a list of study questions that highlight key topics in the

chapter. In order to get the best learning experience, you would

be wise to begin by reading both the learning objectives and the

summary and then reviewing the questions at the end of the

chapter.

For the Instructor

Instructors: if you have adopted this book for your course, would

you be so kind as to let us know in the instructor survey?

Learning objectives can be found at the beginning of each

chapter. Of course, all chapters are recommended for use in an

introductory information systems course. However, for courses on

a shorter calendar or courses using additional textbooks, a review

of the learning objectives will help determine which chapters can be

omitted.

At the end of each chapter, there is a set of study questions and

exercises (except for chapter 1, which only offers study questions).

The study questions can be assigned to help focus students’ reading

on the learning objectives. The exercises are meant to be a more

in-depth, experiential way for students to learn chapter topics. It

is recommended that you review any exercise before assigning it,

adding any detail needed (such as length, due date) to complete the

assignment. Some chapters also includes lab assignments.

As an open textbook, support for supplemental materials relies

on the generosity of those who have created them and wish to

share them. Supplemental materials, including slides and quizzes,

are located on the home page for this book. If you wish to contribute

Chapter 1: What Is an Information System?

Learning Objectives

Upon successful completion of this chapter, you will be

able to:

• define what an information system is by identifying

its major components;

• describe the basic history of information systems;

and

• describe the basic argument behind the article

“Does IT Matter?” by Nicholas Carr.

Introduction

Welcome to the world of information systems, a world that seems to

change almost daily. Over the past few decades information systems

have progressed to being virtually everywhere, even to the point

where you may not realize its existence in many of your daily

activities. Stop and consider how you interface with various

components in information systems every day through different

Chapter 1: What Is an Information System? | 9

electronic devices. Smartphones, laptop, and personal computers

connect us constantly to a variety of systems including messaging,

banking, online retailing, and academic resources, just to name a

few examples. Information systems are at the center of virtually

every organization, providing users with almost unlimited

resources.

Have you ever considered why businesses invest in technology?

Some purchase computer hardware and software because everyone

else has computers. Some even invest in the same hardware and

software as their business friends even though different technology

might be more appropriate for them. Finally, some businesses do

sufficient research before deciding what best fits their needs. As

you read through this book be sure to evaluate the contents of each

chapter based on how you might someday apply what you have

learned to strengthen the position of the business you work for, or

maybe even your own business. Wise decisions can result in stability

and growth for your future enterprise.

Information systems surround you almost every day. Wi-fi

networks on your university campus, database search services in

the learning resource center, and printers in computer labs are

good examples. Every time you go shopping you are interacting

with an information system that manages inventory and sales. Even

driving to school or work results in an interaction with the

transportation information system, impacting traffic lights,

cameras, etc. Vending machines connect and communicate using

the Internet of Things (IoT). Your car’s computer system does more

than just control the engine – acceleration, shifting, and braking

data is always recorded. And, of course, everyone’s smartphone is

constantly connecting to available networks via Wi-fi, recording

your location and other data.

Can you think of some words to describe an information system?

Words such as “computers,” “networks,” or “databases” might pop

into your mind. The study of information systems encompasses a

broad array of devices, software, and data systems. Defining an

10 | Information Systems for Business and Beyond (2019)

information system provides you with a solid start to this course

and the content you are about to encounter.

Defining Information Systems

Many programs in business require students to take a course in

information systems. Various authors have attempted to define the

term in different ways. Read the following definitions, then see if

you can detect some variances.

• “An information system (IS) can be defined technically as a set

of interrelated components that collect, process, store, and

distribute information to support decision making and control

in an organization.” 1

• “Information systems are combinations of hardware, software,

and telecommunications networks that people build and use to

collect, create, and distribute useful data, typically in

organizational settings.” 2

• “Information systems are interrelated components working

together to collect, process, store, and disseminate

information to support decision making, coordination, control,

analysis, and visualization in an organization.” 3

As you can see these definitions focus on two different ways of

describing information systems: the components that make up an

information system and the role those components play in an

organization. Each of these need to be examined.

Chapter 1: What Is an Information System? | 11

The Components of Information Systems

Information systems can be viewed as having five major

components: hardware, software, data, people, and processes. The

first three are technology. These are probably what you thought

of when defining information systems. The last two components,

people and processes, separate the idea of information systems

from more technical fields, such as computer science. In order to

fully understand information systems, you will need to understand

how all of these components work together to bring value to an

organization.

Technology

Technology can be thought of as the application of scientific

knowledge for practical purposes. From the invention of the wheel

to the harnessing of electricity for artificial lighting, technology has

become ubiquitous in daily life, to the degree that it is assumed

to always be available for use regardless of location. As discussed

before, the first three components of information systems –

hardware, software, and data – all fall under the category of

technology. Each of these will be addressed in an individual chapter.

At this point a simple introduction should help you in your

understanding.

Hardware

Hardware is the tangible, physical portion of an information system

– the part you can touch. Computers, keyboards, disk drives, and

flash drives are all examples of information systems hardware. How

12 | Information Systems for Business and Beyond (2019)

these hardware components function and work together will be

covered in Chapter 2.

Software

Software comprises the set of instructions that tell the hardware

what to do. Software is not tangible – it cannot be touched.

Programmers create software by typing a series of instructions

telling the hardware what to do. Two main categories of software

are: Operating Systems and Application software. Operating

Systems software provides the interface between the hardware and

the Application software. Examples of operating systems for a

personal computer include Microsoft Windows and Ubuntu Linux.

The mobile phone operating system market is dominated by Google

Android and Apple iOS. Application software allows the user to

perform tasks such as creating documents, recording data in a

spreadsheet, or messaging a friend. Software will be explored more

thoroughly in Chapter 3.

Data

The third technology component is data. You can think of data as

a collection of facts. For example, your address (street, city state,

postal code), your phone number, and your social networking

Chapter 1: What Is an Information System? | 13

account are all pieces of data. Like software, data is also intangible,

unable to be seen in its native state. Pieces of unrelated data are

not very useful. But aggregated, indexed, and organized together

into a database, data can become a powerful tool for businesses.

Organizations collect all kinds of data and use it to make decisions

which can then be analyzed as to their effectiveness. The analysis

of data is then used to improve the organization’s performance.

Chapter 4 will focus on data and databases, and how it is used in

organizations.

Networking Communication

Besides the technology components (hardware, software, and data)

which have long been considered the core technology of

information systems, it has been suggested that one other

component should be added: communication. An information

system can exist without the ability to communicate – the first

personal computers were stand-alone machines that did not access

the Internet. However, in today’s hyper-connected world, it is an

extremely rare computer that does not connect to another device

or to a enetwork. Technically, the networking communication

component is made up of hardware and software, but it is such a

core feature of today’s information systems that it has become its

own category. Networking will be covered in Chapter 5.

People

Jeff Bezos, Amazon CEO

When thinking about information

systems, it is easy to focus on the

technology components and forget to

look beyond these tools to fully

understand their integration into an

organization. A focus on the people

involved in information systems is the

next step. From the front-line user

support staff, to systems analysts, to

developers, all the way up to the chief

information officer (CIO), the people

involved with information systems are

an essential element. The people

component will be covered in Chapter 9.

Process

The last component of information systems is process. A process

is a series of steps undertaken to achieve a desired outcome or

goal. Information systems are becoming more integrated with

organizational processes, bringing greater productivity and better

control to those processes. But simply automating activities using

technology is not enough – businesses looking to utilize

information systems must do more. The ultimate goal is to improve

processes both internally and externally, enhancing interfaces with

suppliers and customers. Technology buzzwords such as “business

process re-engineering,” “business process management,” and

“enterprise resource planning” all have to do with the continued

improvement of these business procedures and the integration of

technology with them. Businesses hoping to gain a competitive

advantage over their competitors are highly focused on this

component of information systems. The process element in

information systems will be discussed in Chapter 8.

The Role of Information Systems

You should now understand that information systems have a

number of vital components, some tangible, others intangible, and

still others of a personnel nature. These components collect, store,

organize, and distribute data throughout the organization. You may

have even realized that one of the roles of information systems

is to take data and turn it into information, and then transform

that information into organizational knowledge. As technology has

developed, this role has evolved into the backbone of the

organization, making information systems integral to virtually every

business. The integration of information systems into organizations

has progressed over the decades.

The Mainframe Era

From the late 1950s through the

1960s, computers were seen as

a way to more efficiently do

calculations. These first

business computers were

room-sized monsters, with

several machines linked

together. The primary work was to organize and store large volumes

of information that were tedious to manage by hand. Only large

businesses, universities, and government agencies could afford

them, and they took a crew of specialized personnel and dedicated

facilities to provide information to organizations.

Time-sharing allowed dozens or even hundreds of users to

simultaneously access mainframe computers from locations in the

same building or miles away. Typical functions included scientific

calculations and accounting, all under the broader umbrella of “data

processing.”

In the late 1960s,

Manufacturing Resources

Planning (MRP) systems were

introduced. This software,

running on a mainframe

computer, gave companies the

ability to manage the

manufacturing process, making it more efficient. From tracking

inventory to creating bills of materials to scheduling production, the

MRP systems gave more businesses a reason to integrate computing

into their processes. IBM became the dominant mainframe

company. Continued improvement in software and the availability

of cheaper hardware eventually brought mainframe computers (and

their little sibling, the minicomputer) into most large businesses.

Today you probably think of Silicon Valley in northern California

as the center of computing and technology. But in the days of the

mainframe’s dominance corporations in the cities of Minneapolis

and St. Paul produced most computers. The advent of the personal

computer resulted in the “center of technology” eventually moving

to Silicon Valley.

Chapter 1: What Is an Information System? | 17

IBM PC

The PC Revolution

In 1975, the first microcomputer was announced on the cover of

Popular Mechanics: the Altair 8800. Its immediate popularity

sparked the imagination of entrepreneurs everywhere, and there

were soon dozens of companies manufacturing these “personal

computers.” Though at first just a niche product for computer

hobbyists, improvements in usability and the availability of practical

software led to growing sales. The most prominent of these early

personal computer makers was a little company known as Apple

Computer, headed by Steve Jobs and Steve Wozniak, with the hugely

successful “Apple II.” Not wanting to be left out of the revolution,

in 1981 IBM teamed with Microsoft, then just a startup company,

for their operating system software and hurriedly released their

own version of the personal computer simply called the “PC.” Small

businesses finally had affordable computing that could provide

them with needed information systems. Popularity of the IBM PC

gave legitimacy to the microcomputer and it was named

Time magazine’s “Man of the Year” for 1982.

Because of the IBM PC’s open

architecture, it was easy for

other companies to copy, or

“clone” it. During the 1980s,

many new computer

companies sprang up, offering

less expensive versions of the

PC. This drove prices down and

spurred innovation. Microsoft

developed the Windows

operating system, with version

3.1 in 1992 becoming the first

commercially successful release. Typical uses for the PC during this

period included word processing, spreadsheets, and databases.

18 | Information Systems for Business and Beyond (2019)

Registered Trademark of SAP

These early PCs were standalone machines, not connected to a

network.

Client-Server

In the mid-1980s, businesses began to see the need to connect their

computers as a way to collaborate and share resources. Known as

“client-server,” this networking architecture allowed users to log

in to the Local Area Network (LAN) from their PC (the “client”) by

connecting to a central computer called a “server.” The server would

lookup permissions for each user to determine who had access to

various resources such as printers and files. Software companies

began developing applications that allowed multiple users to access

the same data at the same time. This evolved into software

applications for communicating, with the first popular use of

electronic mail appearing at this time.

This networking and data

sharing all stayed mainly within

the confines of each business.

Sharing of electronic data

between companies was a very

specialized function.

Computers were now seen as tools to collaborate internally within

an organization. These networks of computers were becoming so

powerful that they were replacing many of the functions previously

performed by the larger mainframe computers at a fraction of the

cost. It was during this era that the first Enterprise Resource

Planning (ERP) systems were developed and run on the client-server

architecture. An ERP system is an application with a centralized

database that can be used to run a company’s entire business. With

separate modules for accounting, finance, inventory, human

resources, and many more, ERP systems, with Germany’s SAP

Chapter 1: What Is an Information System? | 19

ARPANet, 1969

leading the way, represented the state of the art in information

systems integration. ERP systems will be discussed in Chapter 9.

The Internet, World Wide Web and E-Commerce

The first long distance

transmission between two

computers occurred on

October 29, 1969 when

developers under the direction

of Dr. Leonard Kleinrock sent

the word “login” from the

campus of UCLA to Stanford

Research Institute in Menlo

Park, California, a distance of

over 350 miles. The United

States Department of Defense

created and funded ARPA Net

(Advanced Research Projects

Administration), an

experimental network which

eventually became known as

the Internet. ARPA Net began with just four nodes or sites, a very

humble start for today’s Internet. Initially, the Internet was confined

to use by universities, government agencies, and researchers. Users

were required to type commands (today we refer to this as

“command line”) in order to communicate and transfer files. The

first e-mail messages on the Internet were sent in the early 1970s as

a few very large companies expanded from local networks to the

Internet. The computer was now evolving from a purely

computational device into the world of digital communications.

In 1989, Tim Berners-Lee developed a simpler way for researchers

to share information over the Internet, a concept he called the

20 | Information Systems for Business and Beyond (2019)

Registered trademark of Amazon.com, Inc.

World Wide Web. 4 This invention became the catalyst for the growth

of the Internet as a way for businesses to share information about

themselves. As web browsers and Internet connections became the

norm, companies rushed to grab domain names and create

websites.

In 1991 the National Science

Foundation, which governed

how the Internet was used,

lifted restrictions on its

commercial use. Corporations

soon realized the huge potential of a digital marketplace on the

Internet and in 1994 both eBay and Amazon were founded. A mad

rush of investment in Internet-based businesses led to the dot-com

boom through the late 1990s, and then the dot-com bust in 2000.

The bust occurred as investors, tired of seeing hundreds of

companies reporting losses, abandoned their investments. An

important outcome for businesses was that thousands of miles of

Internet connections, in the form of fiber optic cable, were laid

around the world during that time. The world became truly “wired”

heading into the new millenium, ushering in the era of globalization,

which will be discussed in Chapter 11. This TED Talk video focuses

on connecting Africa to the Internet through undersea fibre optic

cable.

The digital world also became a more dangerous place as virtually

all companies connected to the Internet. Computer viruses and

worms, once slowly propagated through the sharing of computer

disks, could now grow with tremendous speed via the Internet.

Software and operating systems written for a standalone world

found it very difficult to defend against these sorts of threats. A

whole new industry of computer and Internet security arose.

Information security will be discussed in Chapter 6.

Web 2.0

As the world recovered from the dot-com bust, the use of

technology in business continued to evolve at a frantic pace.

Websites became interactive. Instead of just visiting a site to find

out about a business and then purchase its products, customers

wanted to be able to customize their experience and interact online

with the business. This new type of interactive website, where you

did not have to know how to create a web page or do any

programming in order to put information online, became known as

Web 2.0. This new stage of the Web was exemplified by blogging,

social networking, and interactive comments being available on

many websites. The new Web 2.0 world, in which online interaction

became expected, had a major impact on many businesses and even

whole industries. Many bookstores found themselves relegated to a

niche status. Video rental chains and travel agencies simply began

going out of business as they were replaced by online technologies.

The newspaper industry saw a huge drop in circulation with some

cities such as New Orleans no longer able to support a daily

newspaper.

Disintermediation is the process of technology replacing a

middleman in a transaction. Web 2.0 allowed users to get

information and news online, reducing dependence of physical

books and newspapers.

As the world became more connected, new questions arose.

Should access to the Internet be considered a right? Is it legal

to copy a song that had been downloaded from the Internet? Can

information entered into a website be kept private? What

information is acceptable to collect from children? Technology

moved so fast that policymakers did not have enough time to enact

appropriate laws. Ethical issues surrounding information systems

will be covered in Chapter 12.

The Post-PC World, Sort of

Ray Ozzie, a technology visionary at Microsoft, stated in 2012 that

computing was moving into a phase he called the post-PC world. 5

Now six years later that prediction has not stood up very well to

reality. As you will read in Chapter 13, PC sales have dropped slightly

in recent years while there has been a precipitous decline in tablet

sales. Smartphone sales have accelerated, due largely to their

mobility and ease of operation. Just as the mainframe before it, the

PC will continue to play a key role in business, but its role will

be somewhat diminished as people emphasize mobility as a central

feature of technology. Cloud computing provides users with mobile

access to data and applications, making the PC more of a part of

the communications channel rather than a repository of programs

and information. Innovation in the development of technology and

communications will continue to move businesses forward.
