  1. BUS311: Information Systems (IS) in a Global Business Environment • Using MIS 2e, Chapter 1, MIS and You • David Kroenke • Instructor: Prof. Xuefei (Nancy) Deng • Course URL: http://ndeng.shidler.hawaii.edu/bus311_2009.htm

  2. REMINDER: Word Processing Exercise • Write 2-page essay to • 1) Evaluate your computer skills • Refer to the “Required Computer Skills” posted online on course schedule. • 2) Write about the important things to you about picking a major. If you have already picked a major, tell why you selected it. • 3) List your FALLL semester courses in a table format. • Formatting: • Text should be double spaced, 12-point size • The footer should have the “Page <pagenumber>” flush right. • Margins should be one inch all around. • Begin your essay with a title that is Centered, Boldface, and 16-point Arial. • Follow the title with your name on another line. Centered, Times Roman, Bold, 14 points • Follow your name with another line, “BUS 311” followed by your section number (section 002) • DUE: A hard-copy due next Tuesday, 9/1, in class

  3. Q4 – What is Information? • An information system is • – an assembly of hardware, software, data, procedures, and people that interact to produce information. • Information is: • Knowledge derived from data. • Data presented in a meaningful context. • Data processed by summing, ordering, averaging, grouping, comparing, or other similar operations. • All of these definitions will do, choose the definition that works best for the situation – remember the important point is to discriminate between data and information.

  4. Distinction between: Data – raw, unformatted information E.g.: 5433333353 Information – data that is transformed to have a meaning E.g.: (543) 333-3353 Knowledge – body of governing procedures used to organize or manipulate data Wisdom – accumulated knowledge Source: Jessup and Valacich, 2008.

  6. Q5 –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. • Just barely sufficient • – if your boss wants to know how to send an email, you shouldn’t teach her how to build a computer. • Worth its cost • – is it cost worthy to map out the entire U.S. if you only need one state?

  7. Application Exercises (page. 26) • The spreadsheet in Microsoft Excel file Ch1Ex1 contains records of employee activity on special projects. Open this workbook and examine the data that you find in the three spreadsheets it contains. • Assess the accuracy, relevancy, and sufficiency of this data to the following people and problems.

  8. Application Exercises (page. 26) a. You manage the Denver plant, and you want to know how much time your employees are spending on special projects. b. You manage the Reno plant, and you want to know how much time your employees are spending on special projects. c. You manage the Quota Computation project in Chicago, and you want to know how much time your employees have spent on that project.

  9. Application Exercises (page. 26) d. You manage the Quota Computation project for all three plants, and you want to know the total time your employees have spent on your project. e. You manage the Quota Computation project for all three plants, and you want to know the total labor cost for all employees on your project. f. You manage the Quota Computation project for all three plants, and you want to know how the labor-hour total for your project compares to the labor-hour totals for the other special projects. g. What conclusions can you make from this exercise?

  10. Information technology drives the development of new information systems. Information Systems include five components Hardware Software Data Procedures People Q6 – What is the Difference Between Information Technology and Information Systems? • Information technology pertains to • Products • Methods • Inventions • Standards

  11. Q6 – What is the Difference Between Information Technology and 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 yearsand 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

  12. Q6 – What is the Difference Between Information Technology and Information Systems? Figure 1-6 Computer Price/Performance Ratio Decreases

  13. Case Study 1: Requirements Creep at the IRS (page 26) • 1. Why did the Oversight Board place leadership and ownership of the Modernization program on the business units? Why did it not place these responsibilities on the ITS organization?

  14. Case Study 1: Requirements Creep at the IRS (page 26) • 2. Why did the Oversight Board place the responsibility for controlling scope changes on the business units? Why was this responsibility not given to the BSM? To ITS? To Computer Sciences Corporation?

  15. Case Study 1: Requirements Creep at the IRS (page 26) • 3. The second recommendation is a difficult assignment, especially considering the size of the IRS and the complexity of the project. How does one go about creating “an environment of trust, confidence, and teamwork?”

  16. Case Study 1: Requirements Creep at the IRS (page 26) • 4. The problem in question 3 involves at most a few hundred people and a few sites. The IRS problem involves 100,000 people and over 1,000 sites. How would you modify your answer to question 3 for a project as large as the IRS’s?

  17. Case Study 1: Requirements Creep at the IRS (page 26-27) • 5. If the existing system works (which apparently it does), why is the BSM needed? Why fix a system that works?
