End of the computer age
Beginning of the information age
6Computer Age vs. Information Age
- Computer age refers to the love affair with
hardware (and its speed of processing data) - Information age refers to the trend toward
treating information as a corporate resource that
supplies executives with timely, accurate
information for more effective decision making.
7What is Information ?
INFORMATION
Information is refined data.
8Data vs. Information
- Users really want is
- Information
- What users can learn from the data
- how to satisfy their best customers
- how to allocate their resources most efficiently,
- how to minimize losses

11FUNCTIONS OF AN INFORMATION SYSTEM
TM -11
Dr. Chen, Information Age
12Information and our Life
- Information (and energy) are at the core of
everything around us. - Our entire existence is a process of gathering,
analyzing, understanding, and acting on the
information.
13Information and Business
- Every business is a service business
- information confers competitive advantage
- Mass customization
- needs more information for custom-fit
- Information as product
- information broker, e.g., clothing database,
purchasing habits etc. -
14Information and Business
- Modern organizations are said to be drowning in
data but starving for information.
15- Information is pivotal in todays business
environment. Success is dependent on its early
and decisive use. A lack of information is a sure
sign for failure. - The rapidly changing environment in which
business operates demands ever more immediate
access to data. (Devlin, 1997)
16- Many corporations are actively looking for new
technologies that will assist them in becoming
more profitable and competitive. Gaining
competitive advantage requires that companies
accelerate their decision making process so that
they can respond quickly to change. One key to
this accelerated decision making is having the
right information, at the right time, easily
accessible (e.g., with the right form). (Poe,
1996)
17More Information ?
- More information is not profitable unless it is
relevant information. - Executives will need better information in the
future if their companies are to be competitive.
18Information
- BAD information is WORSE than ...
NO information.
19 Good and Bad News?
- The good news is that the future success of
companies is through the astute use of
appropriate information, then the future of
IS/MIS will be the design of DSS (Decision
support systems) that facilitate intelligent uses
of appropriate information.
20 - The bad news is that where DSS are available,
they may not be providing enough support to the
decision makers. - ...
- Quality of the information
21Attributes of Information Quality
- We realize that a firm needs better information
to survive and prosper. Therefore, high quality
information products have to be provided to
management.

25Information and Decision Making
- Information can be defined as
- that which resolves uncertainty, and
- decision making as
- progressive resolution of uncertainty.
26- Since powerful behavior by any mechanism (or
organism) depends on sequential decision making,
it is clear that information is required not just
to exist, but to survive, and even to prosper.

Dr. Chen, The Challenge of the Information
Systems Technology
28What is Information Systems?
- Information Systems (IS) are more than computer
hardware and software. - It is not just developing business applications
programs - Information Systems include
- Information Technology
- Management
- Organization
- Ultimately, IS are used as strategic tool to
improve an organizations competitive advantage.
29How you can apply MIS ...
- To improve the information content of the data,
- to present the valuable information in a
user-friendly, intuitive, and easy to understand
way, and - to empower knowledge workers of today and
tomorrow.
30Objectives of the MIS
- Deliver the right information
- to the right people,
- at the right time,
- with the right form.
- Ultimately, MIS should improve the workers
productivity.
- who has what information about whom and when,
where, and how will all be decided in the process
of building an information system.

32Operational Data vs. Informational Data
- Operational data focus on transaction functions
such as bank card withdrawals and deposits - operational system run a business in real time
based on current data. - Informational data is organized around subjects
such as customer, vendor, and product. It focus
on providing answers to problems posed by
decision makers - information systems support decision making based
on point-in-time or historical data.

35Why the Information Gap?
- Information is not integrated.
- Most information systems are developed to support
operation processing (transaction) not for
information processing. - Operation processing captures, stores, and
manipulates data to support daily operations of
the organization. - Information processing is the analysis of
summarized data or other forms of information to
support decision making.
36A Solution to the Information Gap
- A solution to bridging the information gap is the
data warehouses which consolidate and integrate
information from many different sources and
arrange it in a meaningful format for making
accurate business decisions (Martin, 1997)
37Definitions
- Data Warehouse An integrated and consistent
store of subject-oriented data that is obtained
from a variety of sources and formatted into a
meaningful context to support decision-making in
an organization. - Bill Inmon, the acknowledged father of the Data
Warehouse, defines it as an integrated,
subject-oriented, time-variant, non-volatile
database that provides support for decision
making.
38CONCLUSION
- There is no reason to expect an end to an
information age. - On the contrary, it is only reasonable to expect
the rate of producing and consuming the
information to grow.
39CONCLUSION
- Information System (IS) should be an
organizational and management solution, based on
information technology (IT), to a challenge posed
by the environment.
