...COMPARING PERCEPTIONS OF THE SYSTEMS ANALYSIS AND DESIGN COURSE BRANDI N. GUIDRY University of Louisiana at Lafayette Lafayette, LA 70504 DAVID P. STEVENS University of Louisiana at Lafayette Lafayette, LA 70504 ABSTRACT Information Systems (IS) practitioners and educators have equal interest in the content of the Systems Analysis and Design Course (“SAD”). Previous research has examined instructors’ perceptions regarding the skills and topics that are most important in the teaching of the SAD course and the class time devoted to each. A similar assessment evaluated SAD course content from a practitioner perspective. Both studies used entropy calculations. A comparison of these studies is presented in this paper. For traditional topics, the group (either faculty or practitioner) with greater agreement believes the topic to be deserving of less class time. For structured and object-oriented topics, the group with the greater agreement also believes the topic to be of greater importance. This analysis demonstrates that practitioners and academics agree on approximately 40% of the SAD skills and knowledge areas. Keywords: Systems analysis and design, Structured analysis, Object-oriented analysis, Management Information Systems curricula, Entropy INTRODUCTION It is important that an education in Management Information Systems (MIS) is reflective of practices and techniques that are currently used in industry. Given the pace of technological innovation, there are ever-changing...

From Model T’s to Web Sites Kelly Blue Book (K BB) began life in 1918 as Kelly Kar Company with three Ford model T’s for sale in an open lot in Los Angeles, California. By 1926 the company had grown and though to larger sites. Les Kelley, the founder, started distributing a list of automobiles that he wanted to purchase the other dealers, along with the prices that he would pay. Other dealers began to request a list for their own use because they trusted Kelley’s judgment on used car prices. By 1926 the list had been expanded to include all the cars and metamorphic into the first Blue Book of Motor Car Values. Meanwhile, Kelley’s used-car dealership had gone from one employee, his brother, Buster, to an employer of over 100 people, on its way to becoming the largest used car leadership in the world. This was possible because new car dealers did not sell used cars in those days, so the Kelleys not only bought the vehicles that they took in trade for new cars, but also what used cars directly from the public. During the Depression the Kelleys bought entire inventories of dealers who were forced out of business by the economy. Many customers did not know how to drive, so Buster Kelly...

The automobile industry at the time (and still is) was highly competitive and very cyclical. In the late 1960's, America began to see the influences of foreign vehicles. Facts Around 1967 Ford Motor Company decided to design a small size car called the Ford Pinto. The automobile industry at the time (and still is) was highly competitive and very cyclical. In the late 1960's, America began to see the influences of foreign vehicles. Prior to that, cars were bigger and less fuel efficient, allowing the Japanese to gain substantial market share with the smaller, more economical vehicles, and the need to react to this pressure was even greater at Ford. Even though they held the number two spot in market share behind General Motors, they only held a 22.3% market share compared to General Motors at 46.4%, a very significant difference. There was strong competition for Ford in the American small-car market from Volkswagen and several Japanesecompanies in the 1960's. In order for Ford to stay competitive and fight off competition, they rushed its newest car the Ford Pinto into production in much less time than is usually required to develop a car. The regular time to producean automobile was 43 months; Ford took only 38 months. Before production, the engineers at Ford discovered a major flaw in the cars' design. In nearly all rear-end crash test collisions the Pinto's fuel...

...Ford Motor Company Analysis Introduction Ford Motor Company was originally founded by Henry Ford in Dearborn, Michigan on June 16, 1903. Ford Motor Company has a very glamorous history. Since it was found in the early 1900’s, Ford positioned them as the reformer of the car manufacturing industry. Their mission was clearly stated in words, “began a manufacturing revolution with its mass production assembly lines”. And they rendered the corporate strategies matching with their goal in later years. “They introduced methods for large-scale manufacturing of cars and large-scale management of an industrial workforce using elaborately engineered manufacturing sequences typified by moving assembly lines. Henry Ford's methods came to be known around the world as Fordism by 1914”. (“The Ford Story”) http://www.thefordstory.com/ the combination of attractive product design with the efficiency in manufacturing brought them not just profits, but popularity and reputation. Some of their famous classic designs like Model T, 500hp GT, Mustangs, Sport Utility Vehicle (SUV), Taurus and the best-selling F-series truck are still sold well. But Ford has been on the downhill since the beginning of the 21st century. Because of the crush of the bad economy and flawed management strategies, Ford suffered a lot and the previous ranking is now after Toyota and General Motor. It’s quite a burden to the CEO, Alan Mulally, who was elected as the new CEO in 2006 after Bill Ford stepped down...

...MGMT 570 ISSUE PAPER ARE PROFITS THE ONLY BUSINESS OF BUSINESS? CONSUMER NOTIFICATION AND PRODUCT RECALL BY KOLAWOLE OLAYINKA 03/30/2013 ARE PROFITS THE ONLY BUSINESS OF BUSINESS? Supply and demand is at the root of everything, where exchange of goods and services is involved between producers and consumers for mutual benefits. These mutual benefits involve an exchange that provides value to the consumer and profits to the producer. It is not at all farfetched to think of these as basically human characteristics. At the beginning of a spectrum is the producer and at the end of the same, is the consumer. They interact with each other and with the governmental law regulating their transactions. In this economic system, what will be produced is determined by what will yield the greatest profit. From the readings, Milton Friedman and Robert Almeder recognize the merits of a profit-driven economic system. They do not quarrel over the importance of profits. But they do quarrel over whether or not business firms have obligations beyond making profits. A consumer may be a pet owner who feeds and provides care for a beloved animal, a doting grandparent who buys toys and clothes for the grandkids, an individual who wears contact lenses or hearing aids, a patient who buys prescription medications, or vehicle owner. Should a consumer have certain expectations from the suppliers and producers of the products that he buys? Can we trust corporations that they will not produce...

...1. Characteristics' of Car Rental Industry Subsequent are the various characteristics' of car rental industry along with their impact on the design of service delivery process: Intangibility: If it is seen in terms of service, the "service" of car rental is intangible but on the basis of the physical nature of the rented vehicle, it is not as intangible as various other services are. In this industry, the consumer can see and touch the rented vehicle, which is not possible in other services. In this industry the service provided is the physical car. This significantly affects the service delivery process of industry as they have to keep in mind that consumer wants more and more quality and in case of car rental they can easily judge it. Perishability: Car rental service is a perishable service as if a car is not rented for some days, it may direct towards high losses. High fixed costs are associated with car rental service and need to be balanced in significant manner. This characteristic has direct impact on the service delivery process of industry as they have to operate with effective strategies related with perishability. Heterogeneity: Car rental service is not an especially heterogeneous service in comparison to the other services like a doctor, lawyer and an architect. In this industry, the customers may request altered vehicles or additional services for example child seat and ski rack. They may require vehicles on diverse rental terms like return with empty or full tank...

...Subcompact cars were a trend during the 1960’s. Well known international companies such as Volkswagen and Toyota were competing with each other in producing their own subcompact vehicles and fortunately both of these companies were able to succeed in European countries and Japan. Due to the rising demand of this type of automobile, car manufacturers in United States of America started to manufacture their own subcompact cars. The current president of Ford at that time, Lee Iacocca, recognized the market potential for this design of vehicles; he then led the designing of Ford’s first subcompact model car, namely Pinto on the year 1968. Due to the competition from various domestic and international automobile companies, Ford was influenced to accelerate the production of their first subcompact car. After for only 25 months of designing and manufacturing of the vehicle instead of a typical time frame of 43 months, Ford Pinto first debuted into the automotive industry as a two-door sedan with the entry model price at $1850 and followed by a hatchback and wagon version of the car later in 1972. The short time frame of the car from being a conception to the production surely raised some doubt among the sceptical during that time. Nevertheless, Ford Motor Company was still eager to market the car since it was a trend at the time. During the first few years Ford Pinto was introduced to the world, the sales were remarkable. By January 1971, the Pinto had sold over 100,000 units and 352...

...Business Case (The Ford Pinto) There was strong competition for Ford in the American small-car market from Volkswagen and several Japanese companies in the 1960's. To fight the competition, Ford rushed its newest car the Pinto into production in much less time than is usually required to develop a car. The regular time to produce an automobile is 43 months but Ford took 25 months only (Satchi, L., 2005). Although Ford had access to a new design which would decrease the possibility of the Ford Pinto from exploding, the company chose not to implement the design, which would have cost $11 per car, even though it had done an analysis showing that the new design would result in 180 less deaths. The company defended itself on the grounds that it used the accepted risk-benefit analysis to determine if the monetary costs of making the change were greater than the societal benefit. Based on the numbers Ford used, the cost would have been $137 million versus the $49.5 million price tag put on the deaths, injuries, and car damages, and thus Ford felt justified not implementing the design change (Legget, C., 1999). This was a ground breaking decision because it failed to use the common standard of whether a harm was a result of an action on trespass or harm as a result of an action on the case (Ferguson, A., 2005). From reading this case, we realize the company did not apply the managing ethics competency in building its goals and structure. Managing ethics competency involves the overall...
