New IT investments continue to be staggering. Worldwide, over $2.5 trillion is invested in IT. In the U.S., over 50% of capital expenditures are related to IT. Information systems influence business processes, organizational structures, and the ways people do business, work, and communicate. Emerging technologies have triggered new forms of organization and business process innovation; they have also impacted organizational structure, culture, politics, decision making, and society as a whole. IT is transforming how physical products are designed, how services are bundled with products, and how individuals interact with businesses and with other individuals. A silent transformation is occurring as more and more physical products use embedded IT to improve customer experience and product performance. The pervasiveness of IT is expanding global trade and changing how and where work is performed. It is vital that future managers—in every area of business—have a...

Chapter 6

...Chapter 6 ------------------------------------------------- Team Member Roles (Page 134) ------------------------------------------------- The section of chapter 6 talks about the 9 different role theories that can be present in a group setting. This list was developed by R. Meredith Belbin and his team and were created to be seen as an extension of an individual’s personality. Out of the 9 roles that were provided I believe that a group could survive with only 4, the creative problem solver, coordinator, team worker and the specialist. The book defines a role as, “A tendency to behave, contribute, and relate to others in a particular way”. When you combed this with the aspects of what will make a team functional, you could get by with just 4 of the roles because a group will require the collective effort of everyone instead of being a something that could be performed by an individual. With good communication and trust amongst the team anything could be possible. This important in both education and in the work place since both areas rely of the efficient use of their teams to accomplish their goals. ------------------------------------------------- ------------------------------------------------- Work Accomplishment and High Productivity (Page 133) ------------------------------------------------- This area is a key learning point because it gives examples that will help put teamwork into perspective using modern day companies as examples.

...of service attack,“ wrote Stone (Twitter co-found Biz Stone). “Attacks such as this are malicious efforts orchestrated to disrupt and make unavailable services such as online banks, credit card payment gateways, and in this case, Twitter for intended customers or users. We are defending against this attack now and will continue to update our status blog as we continue to defend and later investigate.“ In a denial-of-service attack, a malicious party barrages a server with so many requests that it can’t keep up, or causes it to reset. As a result, legitimate users can only access the server very slowly — or not at all, as appears to be the case here. (www.wired.com, Van Buskirk, Elliott, Denial-of-Service Attack Knocks Twitter Offline, Aug 6, 2009) Computer Crime Computer crime is a growing national and international threat to the continued development of e-business and e-commerce. When the Internet was first created in the late 1960s, the designers intentionally built it to be open and easily accessible. Little did they know 40 years later, that structure would be the very cause of so much crime and vandalism. This table lists the best known examples of computer crime. Identity Theft The fastest growing crime off or on the Internet is identity theft. Even though identity theft is most likely to occur in an offline environment, once your personal information has been stolen its easy to use it in an online environment.

Chapter 6

...Chapter 6 - (30 points) 3. If a person consumes fewer units of a good, will marginal utility of the good increase as total utility decreases? Why or why not? Yes, it will, as long as the marginal utility of the units of the good no longer consumed was not negative. To illustrate, suppose the situation is as shown in Exhibit 1a. If the consumer consumes 5 units of good X, total utility is 40 utils and marginal utility is 6 utils. If she consumes one less unit of good X, or 4 units, total utility drops to 34 utils but marginal utility rises to 7 utils. (5 points) 4. If the marginal utility of good A is 4 utils and its price is $2 and the marginal utility of good B is 6 utils and its price is $1, is the individual consumer maximizing (total) utility if she spends a total of $3 buying one unit of each good? If not, how can more utility be obtained? The individual consumer is not maximizing utility. She is receiving 2 utils per dollar spent on good A and 6 utils per dollar spent on good B. She can increase her utility by purchasing more of good B (the good for which she receives more utility per dollar) and less of good A (the good for which she receives less utility per dollar). (5 points) 1. The marginal utility for the third unit of X is 60 utils and the marginal utility for the fourth unit of X is 45 utils. If the law of diminishing marginal utility holds, what is the minimum total utility? We can’t...

Air Canada Case by Laudon & Laudon

...Case: AIR CANADA TAKES OFF WITH MAINTENIX Air Canada is Canada's most prominent airline. It is the largest provider of scheduled passenger services in the Canadian market, the Canada-U.S. trans-border market, and in the international market to and from Canada. The airline serves over 33 million customers annually and provides direct passenger service to over 170 destinations on five continents. But the company's information systems had plenty of room for improvement. When Air Canada technicians worked on planes, they used several different legacy software packages installed over the past 15 years. The systems weren't able to interact with one another or with finance and inventory systems. The inefficiencies of these systems were costing Air Canada the time of its engineers and money that could have been used on maintaining its planes, instead of needlessly maintaining excess inventory. Air Canada turned to Mxi Technologies for help in addressing these problems. Mxi is reknowned in the airline industry for its Maintenix software package, which provides integrated, intelligent aviation MRO (maintenance, repair, and operations) software to aviation organizations hoping to improve productivity. The benefits of Maintenix that interested Air Canada were enhanced visibility of fleet-wide data, timelier decision-making; support of its currently existing business model, and increased operational efficiencies. Maintenix provides a system platform that is accessible via the......
