Application Case 2-1 (Gen Y Rocks the Business World)

...Application Case 2-1 (Gen Y Rocks the Business World) Question 1: What will organizations have to do to adapt to the influx of needed Generation Y individuals? ANSWER: In fulfilling the demands of technology and to avoid a clash of culture in organization, an adequate knowledge, skills and competencies in various areas by the individual is important. In spite of the influx of workers from different generations as the ‘baby boomers’, Generation X, Generation Y and some of Generation Z in the organization, there arose a great challenge for the management of the organization to put equal importance while dealing with globalization issues. This includes matters relating to the determination of the scope and means of suitable work in accordance with the requirements of technology, which is then adapted to the mentality of these generations. When talking about Generation Y, it can be summarized that individuals of this generation have different way of thinking with Generation X and the gap is too wide with the ‘baby boomers’. Generation Y is known as the person who is never satisfied in finding something that will be the end point of their quest. No wonder if this generation individuals will often switching jobs within a year. What they are looking for is a high income as well as a relatively easy job or do not require a lot of hassle. When organizations decide to hire the Generation Y individuals, what to do next is to ensure that this group remains to provide services in the......

Technology has evolved at a drastic rate and this will continue in the future. Nanotechnology and the many applications associated with it will be a big factor on this evolution. The definition of Nanotechnology according to (The Center for Responsible Nanotechnology) Nanotechnology is the engineering of functional systems at the molecular scale. This covers both current work and concepts that are more advanced to the engineering of functional systems at the molecular scale. Because of the complexity of Nanotechnology and the science that guides it, much of the research in these areas is being conducted by grants to universities, Military research, and the Automotive Industry. There are many who protest this technology because there is still a lot to learn about its capabilities, and it uses. My research will focus on some of the uses of nanotechnology vs. the complexity of designing these devices. In the......

...Contribution and Diversity Questions Your background, experiences, and values will enhance and diversify Kellogg. How? (1-2 double-spaced pages) The Darden School seeks a diverse and unique entering class of future managers. How will your distinctiveness enrich our learning environment and enhance your prospects for success as a manager? Every essay question on the admissions application is geared toward the same thing. Committee members want to find out who you are, what makes you different from everyone else, and how you will contribute to the school if accepted. This question asks these things outright. Because it asks so directly what the admissions committee wants to know, this is one of the most common questions you will find. The question has a structure similar to the Why M.B.A.? question. It asks both Why us? and Why you? However, the nature of this question lends itself to a more personal response. Whereas the Why M.B.A.? question asks what you have done, what you want to do, and how that relates to the school, this question asks about who you are and how it relates to the school. The Why M.B.A.? question asks about your experiences, and this question asks about your qualities. Just as you brainstormed about your experiences, actions, and goals for the first question, brainstorm about your qualities and characteristics for this one. What sets you apart from everyone else? What words do friends and family use to describe you? For some people, the......

... Marketing Mix Crystal Watson MKT/421 February 6, 2013 Brandon Miller University of Phoenix Marketing Mix Marketing is a commonly misrepresented term in today’s business environments. Some organizations and most individuals believe marketing is just about sales and advertising. Often times having such a vague understanding of marketing can determine the success or failure of an organization. In fact, marketing is a much more complex subject and area of business. Known as the four P’s, the marketing mix is a set of four decisions that an organization must make before launching a new product or service. The marketing mix consists of four elements: Product, Place, Price, and Promotion (University of Phoenix, 2011).These four elements work together to assist in making the strategic decisions necessary to ensure a smooth introduction of a product or service. An organization must have a thorough understanding of these four elements as each play a key role when developing an organization marketing strategies and tactics. The pet industry is a steadily rising niche business sector. Climbing up to $50.82 billion in 2011 from $23 billion in 2000, makes the pet industry a hot topic for entrepreneurs and pet lovers alike. Although the pet industry continue to see an increase in revenue, according to the American Veterinary Medical Association (AVMA) American households owned 2 million fewer dogs at the end of 2011 than at the end of 2006 (U.S Pet Ownership &......

...market and reap some very lucrative returns through dividends and capital gains. For investors who invest on the market there are of course some risks that they have to live with, for example, the unexpected crashing of the stock market. According to McGregor companies usually borrow money from banks in order to meet their short-term cash requirements. However, when they need long-term finance, they may sell their ownership interests in the company by using common and preferred stocks. Moreover, they can also borrow from the public by selling bonds to meet their long-term capital requirements. Stocks exist to enable companies in need of long-term finance to sell pieces of their business as stocks (equity securities) in exchange for cash. The selling of equity securities is the principal method of raising long-term capital other than the issuing bonds. The publicly held shares can be traded to other investors on the stock market and are in this case, known to be liquid[5]. According to Stanlake company shares represent permanent loans and there are no rights to repayment of such loans. He also noted that in the absence of some kind of stock exchange, securities such as these will be very illiquid and it would be very difficult to find buyers for them. Hence, the existence of the stock exchange solves this problem because it provides a market where holders ......

As our world changes amongst us, we have to evolve with it or we will find ourselves evaporating as a whole. That is where using the OD principles can help us to break down the problems that we are facing and help us to find either solutions or be on the road to finding solutions to make sure that we make it through these challenges. The first step of the principles suggests that changes to the organization and change relies on value based decisions. Using the value based decisions I would get together with the managers and supervisors of each department to gather their ideas and opinions.

...Indesit, founded in 1975, is an Italian multinational company that produces domestic product to export all over the world. Unfortunately, between 2012 and 2013 it faced a significant downfall related, initially, to one of it’s products, the Indesit washing machine WIXL143 and later on the more expensive W1X E167 model. Several costumers complained about the malfunctioning and the unexpected explosion of the models. One customer explained: “During the spin cycle it appeared that the drum had split open and moved the concrete balancing block inside the machine up pushing it’s top upwards”. Looking at this situation from a lawyer’s perspective the consumer is protected, under the 1979 Soga Act, or in other words the Sale Of Goods act that establishes the rights and duties of the seller and buyer and their remedies in the event of a breach. The Act is defined as “a contract by which the seller transfers or agrees to transfer the property in goods to the buyer for a money consideration called the price”. It is also important to take into consideration that land and money are not included in the definition of goods. Even in the case that no physical contract for the sale of goods has been written, this Act automatically includes a number of conditions and warranties that in law are called ‘implied terms’. There are four main implied conditions, or major terms which are vital to the main purpose of the contract: -Title (s 12) involving the seller and its right to sell the......

Business Intelligence Applications

...What Is Business Intelligence? Business intelligence has become a critical element of information technology. It’s an old term with general or even ambiguous meaning. It has been used synonymously with decision support, analysis, and data warehousing, but today business intelligence has a more specific definition and a better understood application. Taken literally, business intelligence is just that—intelligence or understanding of your business. You get that understanding by analyzing your business operations. That analysis is accomplished by collecting the information that represents your marketing, sales, and service activities, the behavior of your customers in responding to these activities, and the behavior of your internal systems and your suppliers’ systems in responding to your customers’ behavior. Once you have collected this information, and its collection is a continuous process, not a one-time event, you organize and store it in a manner to facilitate its access, processing, and presentation through a broad range of techniques including, reporting, query and analysis, OLAP, and data mining. Finally, you use the results of applying these techniques to improve your business operations and start the analysis cycle all over again. This business intelligence process can deliver significant, bottom-line results. Implementing its technologies and applying its process can help make your business more effective and more efficient, increasing revenue, decreasing......
