Read the Interactive Session and discuss the following questions
Interactive Session: Management
• What kinds of applications are described in the case? What
business functions do they support? How do they improve
operational efficiency and decision making?
• Identify the problems that businesses in this case study
solved by using mobile digital devices.
• What kinds of businesses are most likely to benefit from
equipping their employees with mobile devices?
• Discuss the implications of this statement: “The iPhone is
not a game changer, it’s an industry changer.”
MEET THE NEW MOBILE WORKERS
• In the emerging, fully digital firm:
– Significant business relationships are digitally
enabled and mediated.
– Core business processes are accomplished through
digital networks.
– Key corporate assets are managed digitally.
• Digital firms offer greater flexibility in
organization and management.
– Time shifting, space shifting

• Growing interdependence
between:
– Ability to use information technology
and
– Ability to implement corporate
strategies and achieve corporate goals
• Firms invest heavily in information
systems to achieve six strategic business
objectives:
1. Operational excellence
2. New products, services, and business models
3. Customer and supplier intimacy
4. Improved decision making
5. Competitive advantage
6. Survival
In contemporary systems there is a growing interdependence between a firm’s information systems and its
business capabilities. Changes in strategy, rules, and business processes increasingly require changes in
hardware, software, databases, and telecommunications. Often, what the organization would like to do depends
on what its systems will permit it to do.

• Operational excellence:
– Improvement of efficiency to attain higher
profitability
– Information systems, technology an important
tool in achieving greater efficiency and
productivity
– Walmart’s Retail Link system links suppliers to
stores for superior replenishment system
• New products, services, and business models:
– Business model: describes how company
produces, delivers, and sells product or service to
create wealth
– Information systems and technology a major
enabling tool for new products, services,
business models
•Examples: Apple’s iPad, Google’s Android OS,
and Netflix
• Customer and supplier intimacy:
– Serving customers well leads to customers returning,
which raises revenues and profits.
• Example: High-end hotels that use computers to track
customer preferences and used to monitor and
customize environment
– Intimacy with suppliers allows them to provide vital
inputs, which lowers costs.
• Example: JCPenney’s information system which links
sales records to contract manufacturer

• Improved decision making
– Without accurate information:
• Managers must use forecasts, best guesses, luck
• Results in:
– Overproduction, underproduction
– Misallocation of resources
– Poor response times
• Poor outcomes raise costs, lose customers
– Example: Verizon’s Web-based digital dashboard to
provide managers with real-time data on customer
complaints, network performance, line outages, and
so on
• Competitive advantage
– Delivering better performance
– Charging less for superior products
– Responding to customers and suppliers in
real time
– Examples: Apple, Walmart, UPS
• Survival
– Information technologies as necessity of business
– Industry-level changes
•Example: Citibank’s introduction of ATMs
– Governmental regulations requiring record-
keeping
•Examples: Toxic Substances Control Act,
Sarbanes-Oxley Act
•Dodd-Frank Act

• Information system:
– Set of interrelated components
– Collect, process, store, and distribute
information
– Support decision making, coordination, and
control
• Information vs. data
– Data are streams of raw facts.
– Information is data shaped into meaningful form.
What Is an Information System?
Raw data from a supermarket checkout counter can be processed and organized to produce meaningful
information, such as the total unit sales of dish detergent or the total sales revenue from dish detergent for a
specific store or sales territory.
Figure 1.3
Data and Information
• Three activities of information systems
produce information organizations need
– Input: Captures raw data from organization or
external environment
– Processing: Converts raw data into meaningful
form
– Output: Transfers processed information to
people or activities that use it

• Feedback:
– Output is returned to appropriate members of
organization to help evaluate or correct input stage.
• Computer/computer program vs.
information system
– Computers and software are technical foundation
and tools, similar to the material and tools used to
build a house.
An information system
contains information about an
organization and its
surrounding environment.
Three basic activities—input,
processing, and output—
produce the information
organizations need. Feedback
is output returned to
appropriate people or activities
in the organization to evaluate
and refine the input.
Environmental actors, such as
customers, suppliers,
competitors, stockholders, and
regulatory agencies, interact
with the organization and its
information systems.
Figure 1.4
Functions of an Information System
Using information systems
effectively requires an
understanding of the
organization, management, and
information technology
shaping the systems. An
information system creates
value for the firm as an
organizational and
management solution to
challenges posed by the
environment.

• Organizational dimension of information
systems
– Hierarchy of authority, responsibility
•Senior management
•Middle management
•Operational management
•Knowledge workers
•Data workers
•Production or service workers
Business organizations are
hierarchies consisting of three
principal levels: senior
management, middle
management, and operational
management. Information
systems serve each of these
levels. Scientists and
knowledge workers often work
with middle management.
Figure 1.6
Levels in a Firm
• Organizational dimension of information
systems (cont.)
– Separation of business functions
• Sales and marketing
• Human resources
• Finance and accounting
• Manufacturing and production
– Unique business processes
– Unique business culture
– Organizational politics

• Management dimension of information
systems
– Managers set organizational strategy for
responding to business challenges
– In addition, managers must act creatively:
•Creation of new products and services
•Occasionally re-creating the organization
• Technology dimension of information
systems
– Computer hardware and software
– Data management technology
– Networking and telecommunications technology
•Networks, the Internet, intranets and
extranets, World Wide Web
– IT infrastructure: provides platform that system
is built on
Read the Interactive Session and discuss the following questions
Interactive Session: Organizations
• What are the inputs, processing, and outputs of
UPS’s package tracking system?
• What technologies are used by UPS? How are these
technologies related to UPS’s business strategy?
• What business objectives do UPS’s information
systems address?
• What would happen if these systems were not
available?

• Dimensions of UPS tracking system
– Organizational:
• Procedures for tracking packages and managing
inventory and provide information
– Management:
• Monitor service levels and costs
– Technology:
• Handheld computers, bar-code scanners, networks,
desktop computers, and so on
• Business perspective on information
systems:
– Information system is instrument for creating
value
– Investments in information technology will result
in superior returns:
•Productivity increases
•Revenue increases
•Superior long-term strategic positioning
• Business information value chain
– Raw data acquired and transformed through stages
that add value to that information
– Value of information system determined in part by
extent to which it leads to better decisions, greater
efficiency, and higher profits
• Business perspective:
– Calls attention to organizational and managerial
nature of information systems

From a business perspective, information systems are part of a series of value-adding activities for acquiring,
transforming, and distributing information that managers can use to improve decision making, enhance
organizational performance, and, ultimately, increase firm profitability.
Figure 1-7
The Business Information Value Chain
• Investing in information technology does not
guarantee good returns.
• There is considerable variation in the returns
firms receive from systems investments.
• Factors:
– Adopting the right business model
– Investing in complementary assets (organizational
and management capital)
Although, on average,
investments in information
technology produce returns far
above those returned by other
investments, there is
considerable variation across
firms.
Figure 1.8

• Complementary assets:
– Assets required to derive value from a primary
investment
– Firms supporting technology investments with
investment in complementary assets receive
superior returns
– Example: Invest in technology and the people to
make it work properly
• Complementary assets include:
– Organizational assets, for example:
• Appropriate business model
• Efficient business processes
– Managerial assets, for example:
• Incentives for management innovation
• Teamwork and collaborative work environments
– Social assets, for example:
• The Internet and telecommunications infrastructure
• Technology standards
The study of information
systems deals with issues and
insights contributed from
technical and behavioral
disciplines.
Figure 1.9
Contemporary Approaches to Information Systems

4/5/2016
13
• Technical approach
– Emphasizes mathematically based models
– Computer science, management science, operations
research
• Behavioral approach
– Behavioral issues (strategic business integration,
implementation, etc.)
– Psychology, economics, sociology
Studying Information Systems
• Management Information Systems
– Combines computer science, management science,
operations research, and practical orientation with
behavioral issues
• Four main actors
– Suppliers of hardware and software
– Business firms
– Managers and employees
– Firm’s environment (legal, social, cultural context)
• Approach of this book: Sociotechnical view
– Optimal organizational performance achieved by
jointly optimizing both social and technical systems
used in production
– Helps avoid purely technological approach

4/5/2016

In a sociotechnical perspective, the performance of a system is optimized when both the technology and the
organization mutually adjust to each other until a satisfactory fit is obtained.
