Generic answers will not get much credit(9 points)a. How can value-chain be used by GIANT food store to identify competitive advantage?Giant creates its competitive advantage and reduces buyer power by developing new technologies that make the shopping experience easier and quicker for the customer. Most recently, Giant has announced its new app available for iPhone and Android phone users. Customers can quickly easily access weekly circulars, monitor A+ and Gas Rewards that are synced to their loyalty cards, locate a store when traveling or even call customer service. Not long ago, Giant also added hand-held scanning devices and deli-ordering kiosks to again, make shopping easier and faster.These features and services are offered to lure customers from other grocery store, make Giant more efficient and reduce their competition.b. Expert systems capture human expertise. Will Expert system be ever able to behave like experts? Why or why not?Expert Systems (ES) are an excellent tool for solving problems with rules and procedures that are clearly defined. As we discussed, the field of medicine would benefit tremendously because ES are based on “If-Then” logic. Evaluating a patient’s symptoms and making a diagnosis is an excellent match of the ES abilities to manage and sort through huge amounts of information to solve a problem.I don’t believe, at this time, that ES are able to behave as experts (with 100% accuracy, 100% of the time in all situations) because it is humans that have a hand in creating it.c. How much should a business look into the background of employees to try to identify those with potential problems? What ethical issues arise in this situation?The employee’s right to privacy is a big issue. The establishment of a policy regarding the use of company email and the Internet should put things more in favor of the employer monitoring the employee with the typical scanning or tracking software.Q # 3At Viacom International Inc., the New York based parent of MTV, Mr. John Nutt, the CFO teamed with executives from marketing, sales, manufacturing, human resources and contracting to lead the company into new directions. Because financial processes are so intertwined with the processes in other department, he felt that redesigning finance should ideally be part of company-wide effort. Although some turf were inevitable, executives involved in large scale effort to reorganize the company were persuaded to support company-wide efforts.Some of the goals mentioned were, the new system should allow any department access to “work-in-progress” information. Also, the new system should reduce dependence on paper, particularly financial transactions. Further it should managers more time to analyze the data to make better decisions, rather than spending their time in collecting the data.(4 points)a. What system(s) (ex: DSS, GDSS, NN, SCM, CRM, ES, ERP, GIS etc..) would you advice and why?I would recommend a DSS system because it’s primary objective is to improve the effectiveness of decision makers. The system’s data management component would manage all of the information so the user only needs to request the desired information. The system pulls the information, analyzes it and reports its findings to the requestor who couples the information with their experience and knowledge to then make a better decision.b. What problems might be encountered in installing this system?Interruption of services and access to information will play a big part in deciding how to implement it. Crash, parallel, pilot or plunge will depend on if there is a system already in place, time constraints and ease of use.Ques #4 Identify and discuss four emerging technologies (as discussed in the class) that are performing several tasks for the following situation. Must discuss these technologies in relation to the case below (how technology is functioning and helping them in each case). Generic answers will not get much credit (4 points)Ms Lin and Mr. Johnson are going to Paris . They are stuck in the traffic due to an accident andwill miss their flight on United Airlines. Recognizing this an automated voice-activated system,after discussing with them, arranges for an alternate flight on Air France. They arriveat the IAD (Dulles international) airport and are directed by a voice to an empty space “3C” in the international parking lot.They are cleared through the security by a camera and proceed to boarding gate. They speak their names and are informed by a voice about their seat assignment 5C & 5D and upgrade. When they arrive in Paris they scan their ticket on a machine and their luggage comes rolling in. As soon as they get their luggage their rental car is waiting at the curb to take them to their hotel.Emerging technology One Automatic Speech Recognition(explain how it is helping in the above process)The automated voice-activated system communicates with the travelers, providing them with needed information and processes what they say as well. The language processor is even able to determine which form of the word you are actually using. For example, here and hear, even though they sound the same they have different meanings.Emerging technology TWO Biometrics(explain how it is helping in the above process)Biometrics facilitates the travelers clearing security with a camera; possibly facial recognition software is used. It identifies people by evaluating facial characteristics.Emerging technology THREE_RFID(explain how it is helping in the above process)Their passports were tagged with a RFID chip. The chip sent a signal when they arrived to a reader, alerting the baggage dept they had arrive and were ready to pick up their bags.Emerging technology FOUR cell phone(explain how it is helping in the above process)A cell phone was probably used to place the call to the airport and its GPS provided location updatesQues #5P & B is a defense contractor and every employee has to pass security clearance. They recently fired John Doe who they believe was copying sensitive data from their files. John claims he is innocent. P &B has quarantined his computer. They do find some altered file in their database but are not sure if John altered them. You are a Computer forensics expert and have been hired by P & B to investigate this further.Identify the FOUR steps involved in Forensic investigation and how you will proceed in this case. Must relate steps to the case to get full credit. Generic answers will not get much credit.(5 points)Collect all evidence; the computer and any other devices or information as necessary including passwords. I would ask for a listing of the files they believed were copied. Because he could have printed the documents and copied them on the copier, I would ask for the hard drive in the copier and the printer. I would also ask if the organization had any key logger software installed just to be thorough, as I would imagine if the had, they probably didn’t need me.I would not turn on the computer as this changes things on the computer, but make a forensic image copy of all information on the computer, the hard drive and any other devices.Using special hardware, I could then read the hard drive, emails, documents, view web history, cookies, and deleted and hidden files. Digital software can identify a file’s exact location, the author and the date it was created.The information is then put into context to interpret what actually happened, evaluated and interpreted accordingly. A determination could be made if in fact he files were copied and/or printed, were they emailed to someone and if so who and when.Ques #6Ben & Jerry’s, located in Waterbury, Vermont, produces 190,000 pints of ice cream and frozen yogurt daily to ship to over 50,000 grocery stores in the united states and 12 other countries. Every single pint is meticulously tracked, first by being entered into an ACCESS database with the information carefully organized. Ben & Jerry uses a sophisticated data-mining tool set from a company called Business Objects to track customer tastes.Answer the following:assuming following tables identify Primary (PK) and foreign key (FK)s of the following tables.ICECREAM tableIce_cream_typepriceyears_first offeredtotal_salesVanilla$2/scoop1981$45MCherry$3/scoop1976$45MChocolate$3/scoop1981$60MINGREDIENTIngredient _nameIce_cream_typequantity_usedVanilla beansVanilla20 ozVanilla beansCherry20 ozCherry pitsCherry30 ozEtc…(4 points)a. PK of ICECREAM table___Ice cream type_______PK of INGREDIENT table__Ingredient name_& Ice cream type_______FK of INGREDIENT table___ Ice cream type __________FK of ICE CREAM table___none that I can see__________Draw the relationship (1:1 or 1M or m:n) between ICECREAM and INGREDIENT table. (see page 375) and justify it.(2 points) It would be a 1:many relationship, as there is only one ice cream type, but each type can have many ingredients.Write a query in SQL to get the names of different ice cream types and the years they were first offered in SQL(2 points)In design view, click/add ice cream types information to the query (can have it displayed alphabetized in ascending or descending order by activating the sort feature), then click/add the years they were first offered information. You could have the list displayed so that the ice cream is listed in chronological order by date offering by activating the sort feature on this column.Ques #7. Companies are moving towards internet advertising and joining social networking web sites like Facebook, Myspace, Twitter to market their products. One factor they found to be very important is ‘portability”. Identify how portability can help a company tap into new markets. Discuss this in relation to value chain and Porter’s model.(5 points)There are several markets that are benefiting greatly from being portable. Cell phones, tablets and laptops are just a few. Being able to access the Internet and use Facebook, Twitter and other similar sites with these small devices has created a new media in which to advertise. If these opportunities are overlooked, businesses could be loosing money, especially among the younger generation. Businesses can create a competitive advantage by using the above-mentioned tools to pinpoint their target market and offer products/services that make shopping easier and more efficient, much like the android app for Giant Food. Successful advertising and information gathering will most often result in increased Supplier power and thus reduced Buyer power as they have an inverse relationship. At some point, the competition will have the same or similar technology, but businesses can still maintain their competitive advantage if the switching costs are such that it deters customers from moving to the new supplier. Competition can be intense depending on the industry, and the threat of new entrants can lend to more competition depending on the barriers they have to overcome to enter the market. ................
