retrieves, transforms, and disseminates
information in an organization.
Information Technology


Information
Technology
is
the
integration of computers, communications
equipment, and other technology used in
information systems.
The technology uses to generate
information
is
called
Information
Technology ( IT)
Information Systems vs.


Information
Systems
(IS)
–
all
components and resources necessary to
deliver information and information
processing functions to the organization

Information Technology (IT) – various
hardware components necessary for the
system to operate
Strategic Business Objectives

Business 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

Operational excellence:



Improvement of efficiency to attain higher
profitability
Information systems, technology an important
tool in achieving greater efficiency and
productivity
Walmart’s RetailLink 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 iPod, iTunes, iPhone, 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 use to monitor
and customize environment
Intimacy with suppliers allows them to provide vital
inputs, which lowers costs

Example: J.C.Penney’s information system which
links sales records to contract manufacturer

Improved decision making

Without accurate information:




Managers must use forecasts, best guesses, luck
Leads to:
 Overproduction, underproduction of goods and services
 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, etc.

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
May be:

Functions of an Information System




Input Function accepts the input data from outside
the system.
Processing Function calculates and in other ways
manipulates the input and stored data.
Output Function produces results of processing for
use outside the system.
Feedback Function is the output that is returned to
appropriate members of the organization to help them
evaluate or correct the input state.
Functions of an Information
System
Information System Resources

People: People are the essential ingredient
for the successful operation of all
information
systems.
These
people
resources includes– end users and IS
specialists.


End users: End users are people who use an
information systems or information it produces.
IS specialists: IS specialists are people who
develop and operate information systems.
Information System Resources

Hardware – physical devices and
materials used in information processing
including computer systems, peripherals,
and media.


Computer systems
Computer peripherals
Information System Resources

Software: Software includes all sets of
information processing instructions.



System software,
Application software
Procedures.
Information Systems Resources (con’t)


Data Resources – facts or observations
about physical phenomena or business
transactions
Network Resources– communications
media and network infrastructure


Communications Media – examples include twisted-pair wire, coaxial
and fiber-optic cables, microwave, cellular, and satellite wireless
technologies
Network Infrastructure – examples include communications
processors such as modems and internetwork processors, and
communications control software such as network operating systems
and Internet browser packages.
Data vs. Information

Data – raw facts or observations typically
about physical phenomena or business
transactions.

Information – data that have been
converted into a meaningful and useful
context for specific end users.
Data Versus Information


Data is a representation of a fact, a
number, a word, an image, a picture or a
sound. For example, the number 10 is
data; it might represent image, a picture, or
a sound.
Information is data that is meaningful or
useful to someone. For example, the
statement “ There are 10 books left in
inventory”.
