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

What is MIS 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

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

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.

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

How Can You Enjoy This Class? 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? © Pearson Prentice Hall 2009

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)

Important questions 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?

Five-Component Framework? 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 © Pearson Prentice Hall 2009

Actors, Instructions & Bridges Actors – hardware and people take actions Instructions – software and procedures provide instructions for actors Bridges – data bridges hardware/software and people/procedures

Automation & Resistance to Change

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.

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.

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. Data (input) Information (output) Processing

Data vs. Information Data raw facts no context just numbers and text 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 Zip Code of Gary Indiana Calumet Indiana

Data vs. Information Information Data 6.34 6.45 6.39 6.62 6.57 6.64 6.71 6.82 7.12 7.06

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

Data  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? 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

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 Raw sales  Demand Forecast Raw parts inventor  Production Forecast  Expected Profits Financial IS Manufacturing IS

One User’s Information is Another User’s Data

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? 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 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

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 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
