Assignment for Chapter 3You are a Systems Analyst hired by zippy.docx
- 1. Assignment for Chapter 3 You are a Systems Analyst hired by zippy freight company, a regional trucking firm which operates 25 small and medium size trucks. Loads and routes are determined by a dispatcher using index cards . She has been doing this job for 25 years, and prides herself on being able to get loads to their destination efficiently. The drivers all respect her knowledge. The company owner has hired you because he wants to expand the company to 50 trucks within the next 12 months. He fears that with double the number of trucks, the dispatcher will not be able to keep up. Your job is to find the best technology solution for scheduling truck deliveries. Many such programs are available, so you have been able to find one that appears to be a good match. It will cost $125,000 for the hardware and software. Respond to each of the following questions with a brief answer, based on what you have learned so far. 1. Do you see any issues with Technical, Organizational, or economic feasibility? What are they? 2. If the owner does not think that he can come up with the $125,000 can you suggest any other options for getting the functionality he needs? What are they? Assignment for Chapter 4 There is a problem set of 15 problems for chapter 4 on pages 125 to 127 of your book . In a Word document, prepare responses to problems 4 and 5. You only need to do three questions instead of six ofr each one though. Submit to this link by Wednesday of next week before noon. First Assignment for Chapter 7
- 2. Use Microsoft Word or the drawing application of your choice to create a context diagram for a hypothetical system design. Show at least two external entities and at least two data flows connecting the context diagram to each entity. Accompany this with a description in your words addressing the following: 1) What functionality and what organization does the design apply to? 2) What information does each of the external entities put into or take out of the system? 3) What data elements are included in each data flow? Example of #3: The data flow named "Student Biodata" contains the following elements: Gender (M/F), Date of Birth (date), Years of Education (integer), and Marital Status (Marrried/Not Married). Chapter 8 Assignment Look around your house, apartment, or dorm room. Pick an object that you might want to store information about for some reason. Perhaps you would be in business to sell, repair, or collect it. Now think of six attributes of that object that you would want to store which would be useful in describing it to potential buyers, owners, or collectors. Create a word table with the following headings: Element Name, Description, Data Type, Data Rules. List your six attributes, making an appropriate entry in each column. The data rules could be simple, such as 'Non-Negative' if you are storing the weight of something. If by its nature a data element has only a few values (such as 'operating system' for a computer) you could enter 'pick from lookup table' as a data rule. In this case, show your lookup table as a one-column table below your main table and include some representative values. Due before noon next Wednesday.

Ever since you walked through the door, your interviewee,
- 9. Max Hugo, has been shuffling papers, looking at his watch, and drumming on his desk with his fingers, Based on what you know about interviews, you guess that Max is nervous because of the other work he needs to do. In a paragraph, describe how you would deal with this situation so that the interview can be accomplished with Max's full attention. (Max cannot reschedule the interview for a different dav') 4. Write a series of six closed qlestions that cover the subject of decision-making style for the manager described in Problem 2. 5. Write a series of six open-ended questions that cover the subject of decision-making style for the manager described in Problem 2. 6. Examine the interview structure presented in the sequencing of the following questions: 1. How long have you been in this position? 2. What are your key responsibilities? 3. What reports do you receive? 4. How do you view the goals of your department? 5. How would you describe your decision-making process? 6. How can that process best be supported? 7. How frequently do you make those decisions? 8. Who is consulted when you make a decision? 9. What is the one decision you make that is essential to departmental functioning?
- 10. a. What structure is being used? How can you tell? b. Restructure the interview by changing the sequence of the questions (you may omit some, if necessary). Label the reordered questions with the name of the structure you have used. 7. The following is the first interview report f,led by one of your systems analysis team members: "In my opinion, the interview went very well. The subject allowed me to talk with him for an hour and a half. He told me the whole history of the business, which was very interesting. The subject also men- tioned that things have not changed all that much since he has been with the flrm, which is about 16 years. We are meeting again soon to finish the interview because we did not have time to go into the questions I prepared." a. In two paragraphs, critidue the interview report. What critical information is missing? b. What information is extraneous to the interview report? c. If what is reported actually occurred, what three suggestions do you have to help your teammate conduct a better interview next time? 8. Cab Wheeler is a newly hired systems analyst with your group. Cab has always felt that question- naires are a waste. Now that you will be doing a systems project for MegaTrucks, Inc., a national
- 11. trucking firm with branches and employees in 130 cities, you want to use a questionnaire to elicit some opinions about the current and proposed systems. a. Based on what you know about Cab and MegaTrucks, list three persuasive reasons why he should use a survey for this study. b. Given your careful arguments, Cab has agreed to use a questionnaire but strongly urges that all questions be open-ended so as not to constrain the respondents. In a paragraph, persuade Cab that closed questions are useful as well. Be sure to point out trade-offs involved with each question type, 9. "Every time we get consultants in here, they pass out some goofy questionnaire that has no mean- ing to us at all. Why don't they bother to personalize it, at least a little?" asks Ray Dient, head of emergency systems. You are discussing the possibility of beginning a systems project with Pohattan Power Company (PPC) of Far Meltway, New Jersey. a. What steps will you follow to customize a standardized questionnaire? b. What are the advantages of adapting a questionnaire to a particular organization? What are the disadvantages?
- 12. 10. A sample question from the draft of the Pohattan Power Company questionnaire reads: I have been with the company: 2G-upwards years 10-15 years upwards 5-10 years upwards less than a year Check one that most apPtes. a. What kind of a scale is the question's author using? b. What errors have been made in the construction of the question, and what might be the possible responses? c. Rewrite the question to achieve clearer results. d. Where should the question you've written appear on the questionnaire?
