Slide 3
The Big Questions What is MIS? What should you learn from this
class? How can you enjoy this class?
Slide 4
What is MIS MISmanagement information systemsis the development
and use of information systems that help businesses achieve their
goals and objectives Three key elements: Components of information
systems Development and use of information systems Achieving
business goals and objectives
Slide 5
What is MIS Information Systems components Hardware desktops,
laptops, PDAs Software operating systems, application programs Data
facts and figures entered into computers Procedures how the other
four components are used People users, technologists, IS
support
Slide 6
Development and Use of Information Systems You might Specify
the requirements of an information systems Manage development
projects that use information systems and technology You must Use
information systems effectively and responsibly.
Slide 7
The Core Purpose of all Management information systems Helps a
business achieve goals and objectives Increase sales / grow the
business Increase efficiency / cut costs Make more money Gain a
competitive advantage
Slide 8
How Can You Enjoy This Class? Pearson Prentice Hall 2009 Think
about the information systems around you and how they interact with
each other. How do they affect your life and your job. Every day
you touch dozens of information systems. Does the information
provided make a difference? Do the systems and information impact
your personal life and your job?
Slide 9
Functional Areas Early information system were designed to help
business in key functional areas. Accounting (Transaction
Management) Finance (Investment Management) Marketing (Advertizing
and Sales Management) Human Resources (People Management)
Operations (Production Management)
Slide 10
Important questions 1-10 What is the five-component framework
and why is it important? What is information? What are the
characteristics of good information? What is the difference between
information technology and information systems?
Slide 11
Five-Component Framework? Pearson Prentice Hall 2009 1-11 Five
components interact with each other to create a complete
information system Why is this important In a business you are part
of the information system Most people think of IS as hardware and
software only Data, Procedures and People are the more crucial
components
Slide 12
Actors, Instructions & Bridges 1-12 Actors hardware and
people take actions Instructions software and procedures provide
instructions for actors Bridges data bridges hardware/software and
people/procedures
Slide 13
Automation & Resistance to Change
Slide 14
High Tech vs. Low Tech Low tech using an email program just a
small amount of work is being accomplished by a computer system.
High tech implementing a customer support system large amount of
work is being accomplished by the computer system rather than
humans.
Slide 15
How Can You Use the Five-Component Framework? After this class,
youll look at an information system and evaluate each component
separately and then as a whole system. Hardware is often the
easiest component to identify and evaluate Identifying and
evaluating the role of the people can be tricky, but leads to a
great understanding.

Slide 17
What is Information? before we really talk about Information
Systems Information is: Knowledge derived from data. Data presented
in a meaningful context. Data processed by summing, ordering,
averaging, grouping, comparing, or other similar operations. A
difference that makes a difference. Processing Data (input)
Information (output)
Slide 18
Data vs. Information Data raw facts no context just numbers and
text Information data with context processed data value-added to
data summarized organized analyzed
Slide 19
Data vs. Information Data: 51009 Information: 5/10/09 $51,009
51009 Zip Code of Gary Indiana
Slide 20
Data vs. Information Data 6.34 6.45 6.39 6.62 6.57 6.64 6.71
6.82 7.12 7.06 Information
Slide 21
Data Information Knowledge Data Information Summarizing the
data Averaging the data Selecting part of the data Graphing the
data Adding context Adding value
Slide 22
Data Information Knowledge Information Knowledge How is the
info tied to outcomes? Are there any patterns in the info? What
info is relevant to the problem? How does this info effect the
system? What is the best way to use the info? How can we add more
value to the info?
Slide 23
What is Information? 1-23 Information vs. Data is Subjective
What some people consider information, others think of as raw data.
Context changes occur in information systems when the output of one
system is input to another system
Slide 24
What is Information? 1-24 Information is Subjective Data in a
manufacturing system may be very important to that system. When its
combined with data from other systems, it may lose its prominence
in the larger context. Manufacturing IS Financial IS Sales IS
Slide 25
One Users Information is Another Users Data 1-25
Slide 26
Characteristics of Good Information? 1-26 Accurate entering
incorrect sales data creates false information. Timely knowing that
production doesnt have enough raw materials for next weeks schedule
wont be useful information three weeks from now. Relevant if your
boss needs to know how many shipments were late last month, you
shouldnt give him a list of all items that shipped. Worth its cost
is it cost worthy to map out the entire U.S. if you only need one
state? These are just a few characteristics that are
important...
Slide 27
Information Technology vs. Information Systems? 1-27 Because
many people confuse the two terms, compare what each one consists
of and how the two differ. Information technology drives the
development of new information systems. Information Systems include
five components Hardware Software Data Procedures People
Information technology pertains to New Products New Methods
Inventions Standards
Slide 28
Information Technology vs. Information Systems? 1-28 Moores Law
The number of transistors per square inch on an integrated chip
doubles every 18 months. Dramatic Reduction in Price/Performance
Ratio Ratio fallen dramatically for over 40 years and is estimated
to continue to fall in accordance with Moores Law. Enabled
developments such as: Laser printers, Graphical user interfaces,
High-speed communications, Cell phones, PDAs, Email, Internet
