The Big Questions What is MIS? What should you learn from this class? How can you enjoy this class? 1 -3

What is MIS—management information systems—is 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 1 -4

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 1 -5

What is MIS Development and Use of Information Systems take an active role in specifying requirements and helping manage development projects since you are the one who’ll be using the system to do your job. using information systems responsibly and protecting the system and its data. 1 -6

What is MIS Achieving Business Goals and Objectives Businesses themselves do not “do” anything. Information systems help people in business achieve the goals and objectives of that business. 1 -7

What should you learn from this class? After this class, you should be… an informed and effective consumer of information technology products and services able to ask pertinent questions able to correctly interpret the responses to your questions able to make wise decisions and manage effectively 1 -8

How Can You Enjoy This Class? Apply what you are learning to situations and organizations of interest to you. 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. Begin to ask yourself about the type of information 1 -9 those systems provide you. Does the information make a difference? How do they impact you in your personal life. Prentice and Hall © Pearson 2009 your job?

Preliminary Questions How can you use the five-component framework? What is information? What are the characteristics of good information? What is the difference between information technology and information systems? 1 -11

How Can You Use the Five. Component Framework? Five components interact with each other to create a complete system The Most Important Component – YOU You are part of every information system that you use Your quality of thinking is a large part of the quality of an information system 1 -12 © Pearson Prentice Hall 2009

How Can You Use the Five. Component Framework? Actors – hardware and people take actions Instructions – software and procedures provide instructions for actors Bridges – data bridges hardware/software and people/procedures 1 -13

How Can You Use the Five. Component Framework? 1 -14

How Can You Use the Five. Component Framework? High-Tech Versus Low Tech – how do you tell the difference? 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. 1 -15 The determining factor is the amount of work that is moved from the human side to the computer side in

How Can You Use the Five. Component Framework? After this class, you’ll 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. 1 -16

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 1 -17

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

Data vs. Information Data: 51009 Information: 5/10/09 $51, 009 51009

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

Data Information Knowledge Data Summarizing the data Averaging the data Selecting part of the data Graphing the data Adding context Adding value Information

Data Information Knowledge Information 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? Knowledge

What is Information? 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 1 -23

What is Information? Information is Subjective Data in a manufacturing system may be very important to that system. When it’s combined with data from other systems, it may lose its prominence in the larger context. Sales IS Financial IS Manufacturing IS 1 -24

One User’s Information is Another User’s Data 1 -25

Characteristics of Good Information? Accurate – entering incorrect sales data creates false information. Timely – knowing that production doesn’t have enough raw materials for next week’s schedule won’t be useful information three weeks from now. Relevant – if your boss needs to know how many shipments were late last month, you shouldn’t 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? 1 -26 These are just a few characteristics that are important. . .

Information Technology vs. Information Systems? Because many people confuse the two terms, compare what each one consists of and how the two differ. Information technology pertains to New Products New Methods Inventions Standards Information Systems include five components Hardware Software Data Procedures People Information technology drives the development of new information systems. 1 -27

Information Technology vs. Information Systems? Moore’s Law “The number of transistors per square inch on an integrated chip doubles every 18 months. ” Dramatic Reduction in Price/Performance Ratio fallen dramatically for over 40 years and is estimated to continue to fall in accordance with Moore’s Law. Enabled developments such as: Laser printers, Graphical user interfaces, High- speed communications, Cell phones, PDAs, Email, Internet 1 -28
