  4. Does Information Technology Matter? • Hackett Group study: “Does IT Matter? Hackett Concludes the Answer is Yes” • World’s best performing companies spent 7% more per employee on IT than typical companies • They recouped the investment fivefold in lower operational costs • Today’s business professionals must know how to develop and use IT Management Information Systems, Sixth Edition

  5. The Power of Digital Systems • Binary counting system uses only two digits: 0 and 1 • Digital systems: • Computers and devices that use the binary system • Can represent any information as a combination of zeros and ones • Information can be represented, stored, communicated, and processed digitally Management Information Systems, Sixth Edition

  6. The Power of Digital Systems (continued) • Digital information is stored and communicated by means of electromagnetic signals in three ways: • Using Electricity (e.g. RAM) • Using Magnetism (e.g. Hard Disk) • Using Light (e.g. CD/DVD) • Why Digital Information? • Extremely fast • Digital copy is an exact copy of the original • Accuracy and speed make digital systems powerful, useful, and important Management Information Systems, Sixth Edition

  7. The Purpose of Information Systems • Businesses use information systems • To make sound decisions • To solve problems • Problem: any undesirable situation • Decision: arises when more than one solution to problem exists (e.g. improve sales, increase enrollment) • Both problem solving and decision making require information Management Information Systems, Sixth Edition

  8. The Purpose of Information Systems (continued) • Keys to success in business: • Gathering correct information efficiently • Storing information • Using information • Purpose of information systems is to support these activities Management Information Systems, Sixth Edition

  9. Data, Information, and Information Systems • “Data,” “information,” and “system” are commonly used terms • Important to understand their similarities and differences Management Information Systems, Sixth Edition

  10. Data vs. Information • Data: a given or fact • Can be number, statement, or picture • Is the raw material in the production of information • Information:facts or conclusions that have meaning within context • Composed of data that has been manipulated (e.g. summarized, computation, statistical analysis) Management Information Systems, Sixth Edition

  11. Data Manipulation • Data is manipulated to make useful information • New information can be generated from data, such as averages, trends, etc. • Survey is common method of collecting data • Raw data is hard to read • Information is more useful to business than data Management Information Systems, Sixth Edition

  12. Data vs. Information • Data: 2455, 2758, 2699, 2913, 2744 • Information: Management Information Systems, Sixth Edition

  13. Generating Information • Process: the manipulation of data • Goal is to produces information • May produce more data • A piece of information (output of a process) in one context may be considered data (input to a process) in another context Management Information Systems, Sixth Edition

  14. Generating Information (continued) Management Information Systems, Sixth Edition

  15. Generating Information (continued) INPUT (Data) PROCESS OUTPUT (Information) Management Information Systems, Sixth Edition

  16. Generating Information (continued) Student List considered Information by Instructors But the higher management like IRPO, VPIA and the President himself considers above as Data not Information. So, for something to be information depends on context or who uses the information/data. Management Information Systems, Sixth Edition

  17. Information in Context • Not all information is useful • To be useful, information must be: • Relevant • Complete • Accurate • In business, information must also be: • Current • Obtained in a cost-effective manner Management Information Systems, Sixth Edition

  18. Information in Context (continued) Management Information Systems, Sixth Edition

  19. Activity No. 2 • On Gardener+ case study on Pages 1-3, help Amanda who is tasked to developed the Information System to identify what are the possible data to be gathered from customers. And then what possible information could be generated out of the gathered data via the system that she is going to develop. (20 pts) • On the Information generated by the system identified above give an example of at least one characteristic that would qualify it as real information. (see Page 11). (10 points) Management Information Systems, Sixth Edition

  20. What Is a System? • System: array of components that work together to achieve goal or goals Simplified Enrollment System for COM Financial Aid Business Office Pay Student Tuition Bill Check Financial Status Bill Students Admission Admit Students Management Information Systems, Sixth Edition

  21. What Is a System? • A System • Accepts input • Processes input • Produces output Management Information Systems, Sixth Edition

  22. What is a System? (continued) • System may have multiple goals • System may contain subsystems • Subsystem: component of a larger system • Subsystems have subgoals that contribute to main goal • Subsystems can receive input from and transfer output to other subsystems Management Information Systems, Sixth Edition

  23. What is a System? (continued) COM Goal : Provide quality adult education MITC Financial Aid Goal : Provide books and other resources like multi-media to enhance student learning Goal : Provide Financial Aid to Students Admission Maintenance Goal : Admit qualified students to the college and keep student academic records Goal : Maintain properties including classrooms as a viable environment for student learning Management Information Systems, Sixth Edition

  24. What is a System? (continued) Management Information Systems, Sixth Edition

  25. What is a System? (continued) • Closed system: has no connections with other systems • Open system: interfaces and interacts with other systems • Often a subsystem of a bigger system • Subsystems by definition are always open • Information system (IS): components that work together to process data and produce information Management Information Systems, Sixth Edition

  26. Information and Managers • Systems thinking: thinking of an organization in terms of subsystems • Powerful management approach that creates a framework for problem solving and decision making • Helps keep managers focused on overall goals • Database: collection of electronic records • Information systems automate exchange of information among subsystems Management Information Systems, Sixth Edition

  27. Without Systems Thinking Sales Department Create a website for Online Customer Orders to automate manual system Manufacturing could not keep up the Demand Management Information Systems, Sixth Edition

  28. With Systems Thinking Shared Database Sales Department Create a website for Online Customer Orders to automate manual system Shipping Dept use record to expedite Shipping and Packaging Manufacturing could use Order records for planning laborers and inventory Management Information Systems, Sixth Edition

  29. Information and Managers (continued) • Information map: description of data and information flow within an organization • Shows a network of information subsystems that exchange information with each other and with the outside world • Information technology: technologies that facilitate construction and maintenance of information systems Management Information Systems, Sixth Edition

  30. The Benefits of Human-Computer Synergy • Humans are relatively slow and make mistakes • Computers cannot make decisions unless programmed to do so • Synergy: combining resources to produce output that exceeds the sum of outputs of the separate resources by themselves • Human-computer combination allows human thought to be translated into efficient processing of data Management Information Systems, Sixth Edition
