(Your name) Problem I – (50 points) (This is a two-part question) Part A: Mark Wahlburg, Donnie Wahlburg, and Chef Paul Wahlburg are the “Wahlburgers” restaurant owners ( ) and they want to spend $100,000 to modernize their restaurant chain by adapting more closely to the preferences of their repeat customers as well as attracting new customers. Chef Paul Wahlburg is hoping the new system will allow him to keeping track of his customers’ likes and dislikes. Moreover, Mark and Donnie are also hoping the new system will capture & track information such as where customers like to sit, what they like to eat, and when they normally arrive at their restaurant. Chef Paul Wahlburg believes that with this new innovation, he will be able to better serve his customers, who will then go online and write positive reviews, which would attract new customers to his restaurant. Chef Paul Wahlburg also believes that his annual revenue of $800,000 will increase every year by 4% (over the next 4 years) when you factor in the additional revenue generated by new customers (in addition to his current repeat customers). Presently Chef Paul Wahlburg spends about 32 percent of each dollar on the cost of food and beverages, 33 percent on salaries and wages, and from 5 percent to 6 percent on restaurant occupancy costs. The Wahlburg Brothers are hoping to have the new information system in place and operational six months from now (Christmas 2021). Chef Paul Wahlburg is also incapable of spending no more than $100,000 on a new information system solution. The Wahlburg Brothers have asked you to develop a system for them that will help make their customers happy while increasing their business. You have heard what the Wahlburg Brothers had to say about their customers. There are certainly more preferences that they can keep track of. Develop a system request for the Wahlburg Brothers as discussed in Chapter 2 of our System Analysis and Design, Eleventh Edition textbook. Part B: “I think it’s only fair to write up all alternatives you’ve considered”, says Rhea Durham (Mark Wahlburg’s wife). “After all, you’ve been working on this systems thing for a while now and I think my husband would be interested to see what you found out.” #ThisIsTakingTooLong Please explain to Rhea why your system proposal will not (should not) contain all the alternatives that your ITEC 630 team has considered with respect to solving the Wahlburg Brother’s information management problem. Also include in your well crafted essay response to Rhea Durham the types of alternatives THAT WILL appear in your final systems proposal to the Wahlburg Brothers. Problem II- (50 points) (This is a 3-part Question) A. Please label each question as either closed question or open-ended question. How many personal computers do you have in this department?How is this task performed?  Why do you perform the task that way? How many hours of training does a clerk receive? How many customers ordered products from the Web site last month? What are users saying about the new system? How are the checks reconciled?  What added features would you like to have in the new billing system? Is the calculation procedure described in the manual? Is there anything else you can tell me about this topic? Do you review the reports before they are sent out? Are the user manuals produced by this department?Describe a feature you would like to see in the new system?Who handles the invoices?How do you resolve accounts payable issues?  B. You are going to interview the local manager of Racing Slicks, a national tire retailer, who has asked you to work as a system analyst on a management information system to provide inventory information. Here are five questions you wrote to prepare for the meeting: 1. Describe key decisions you are responsible for. 2. How well do your employees accept changes in the system? 3. Is the current system providing you with enough information to help you make decisions? 4. Do you have any problems with your current system? 5. What kind of output would you like to see?  What type of format is preferred? Order your questions in (1) a pyramid structure, (2) a funnel structure, and (3) a diamond-shaped structure C.You are a project manager at 5G Inc., specialized in information technology and network engineering. One of your junior systems analyst came to you for some advice regarding atechnology to capture user information requirements. He described to you that he had talked with his client several times in the past week to define user information requirements. Each time he thought he had captured user information requirements, they’ve already changed. Finally, he thinks his clients do not even know what they want for their system. Give your junior systems analyst an advice, in the form of a well written and fluid essay response, of a methodology that he could use to capture user information requirements and explain to him how this technology can help him to better define users’ information requirements. Problem III- (50 points) (This is a 3-part Question) An analyst needs an organized method for collecting facts. Some systems analysts will frequently jump right into interviews. They believe, “Go to the people. That’s where the real facts are!” Wrong! This approach fails to recognize an important fact of life: People must complete their day-to-day jobs. You may be thinking, “But I thought you’ve been seen saying that the system is for people and that direct end user involvement in systems development is essential. Aren’t you contradicting yourself?” Write a well-crafted essay exam response which offers your assessment of the issue. Mr. Barack H. Obama, a district manager for Drewmobile Incorporated, thinks that building a prototype can mean only one thing: a non-working scale model. Barack also believes that this way is too cumbersome to prototype information systems and thus is reluctant to work with you and your ITEC 630 Project Team. Please compare and contrast, via a well written essay exam response, the other kinds of prototypes that are possible so that Mr. Barack Obama has a better understanding of what is prototyping and the value it can provide.
