  2. 2. WHAT IS IT?<br />Management Information System(MIS) is the most recent subfield of the quantitative school.<br />A MIS organizes past, present, and projected data from both internal and external sources and processes it into usable information, which it then makes available to managers at all organizational levels.<br />Contd...<br />
  3. 3. WHAT IS IT?<br />it is an all-inclusive system for providing management with better information for effective decision making. <br />This system is partly a by-product of computer technology which dictates centralisation of data handling and information development for the benefit of entire organisation.<br />
  4. 4. Information Systems<br /><ul><li>Why Do People Need Information?
  5. 5. Individuals - Entertainment and enlightenment
  6. 6. Businesses - Decision making, problem solving and control</li></ul>4<br />
  7. 7. Data, Information, and Systems<br /><ul><li>Data vs. Information
  8. 8. Data</li></ul>A “given,” or fact; a number, a statement, or a picture<br />Represents something in the real world<br />The raw materials in the production of information<br /><ul><li>Information</li></ul>Data that have meaning within a context<br />Data in relationships<br />Data after manipulation<br />5<br />
  9. 9. Data, Information,and Systems<br /><ul><li>Data Manipulation
  10. 10. Example: customer survey</li></ul>Reading through data collected from a customer survey with questions in various categories would be time-consuming and not very helpful.<br />When manipulated, the surveys may provide useful information.<br />6<br />
  11. 11. Figure 1.1 Input-process-output<br />Data, Information,and Systems<br />Generating Information<br /><ul><li>Computer-based ISs take data as raw material, process it, and produce information as output.</li></ul>7<br />

  13. 13. Data, Information, and Systems<br />What Is a System?<br /><ul><li>System: A set of components that work together to achieve a common goal
  14. 14. Subsystem: One part of a system where the products of more than one system are combined to reach an ultimate goal
  15. 15. Closed system: Stand-alone system that has no contact with other systems
  16. 16. Open system: System that interfaces with other systems</li></ul>9<br />

  20. 20. Data, Information,and Systems<br />The Benefits of Human-Computer Synergy<br /><ul><li>Synergy</li></ul>When combined resources produce output that exceeds the sum of the outputs of the same resources employed separately<br /><ul><li>Allows human thought to be translated into efficient processing of large amounts of data</li></ul>13<br />

  22. 22. Data, Information, and Systems<br />The Four Stages of Data Processing<br /><ul><li>Input: Data is collected and entered into computer.
  23. 23. Data processing: Data is manipulated into information using mathematical, statistical, and other tools.
  24. 24. Output: Information is displayed or presented.
  25. 25. Storage: Data and information are maintained for later use.</li></ul>15<br />
  26. 26. Why Study IS?<br />Information Systems Careers<br /><ul><li>Systems analyst, specialist in enterprise resource planning (ERP), database administrator, telecommunications specialist, consulting, etc.</li></ul>Knowledge Workers<br /><ul><li>Managers and non-managers
  27. 27. Employers seek computer-literate professionals who know how to use information technology.</li></ul>Computer Literacy Replacing Traditional Literacy<br /><ul><li>Key to full participation in western society</li></ul>16<br />
  28. 28. Function of MIS<br />Information systems organize data into usable and accessible formats.<br />It stores all the information for better monitoring.<br />They are used to analyze other information systems applied in operational activities in the organization.<br />
  29. 29. Example of MIS<br />The MIS computer is a useful accessory,which would store all the information, made available by :-<br />MINOS (mine operating system)<br />FIDO (Face Information Digested on line) :- For face monitoring and for giving the state the key items of the plant on the face.The following reports are available from the system :<br />Shiftwise face delay summary<br />Shiftwise delay log<br />Shiftwise and weekly face delay analysis<br />
