Dba 7553 Unit Viii Article Critique

...Unit VIII Article Critique Columbia Southern University DBA 7553 1. Introduction of the Article This article is found in the Directors and Boards magazine. It is written by Donald P. Delves who “is president of the Delves Group, a compensation and corporate governance consulting firm that advises boards of directors” (Delves, 2012). The article is titled “What about everyone else? The problem may not be that executives are paid too much, but that employees are paid too little.” 2. Statement of the Problem Studied In this article, Mr. Delves examined why people complain about executive pay, how companies used to inflate employee earnings, and how companies can increase employee wages now. 3. Significance of the Problem Studied With sky rocketing pay for many executives over the last few decades, many employees have wondered why their pay has not also increased. In the past companies have used stock options to provide incentive for employees and to use these as a pathway to increase employee pay. However with the economic recession and many of the changes in accounting practices, companies could no longer use this incentive to increase wages for employees. Thus Mr. Delves presents the question, “what do we do about [increasing employee incentives]?” (Delves, 2012). If this question can be answered, it has the potential to not only increase employee productivity but also to provide them with increased opportunities. ...

Introduction On June 2, 1998, Mayor Schell made a daunting pledge to the community regarding Seattle’s homeless population.

...ventory planning Chapter 12: Inventory planning and...  Study guide | This chapter is relatively unusual in so much as it takes more of a quantitative approach to its topic. While not avoiding quantitative models where they are appropriate, the general approach of this book is to deal with operations management from a ‘general management’ point of view. Here we include some quantitative models of how inventory is managed mainly to demonstrate that some parts of the inventory decision can be quantified. In practice, most of these decision models will be embedded within an operation’s routine stock control computer system. However, whilst working through them remember that it is the underlying principles behind the models which are more important than the mathematics on which the models are based.Your learning objectivesThis is what you should be able to do after reading Chapter 12 and working through this study guide. * Understand what is meant by an inventory and why they exist. * Identify some of the advantages and disadvantages of keeping inventory in an operation. * Understand the basic principles behind the quantitative approaches to deciding how much inventory to keep. * Be able to describe the limitations of traditional quantitative models of inventory decision making. * Identify the two main approaches to managing inventory on an on-going basis.What do we mean by inventory?The chapter discusses inventory (we use the word interchangeably with the word ‘stock’)...

Outsourcing

...Outsourcing: What’s the true Impact? Cameron D. Rafford MGT 580: Intro to Organizational Behavior University of New Hampshire INTRODUCTION Outsourcing has quickly become one of the most controversial business tactics in the United States. Nowadays, if you call the customer service line of a major business or corporation, there’s a good chance you’ll end up talking to someone thousands of miles away. If you go shopping for new clothes, it’s likely that some of the shirts and pants you try on were manufactured by people from foreign countries, in shops far less glamorous than the ones the finished products end up in. Outsourcing is so commonplace in certain industries, we don’t even think twice about it anymore. But over the past few years, the trend has spread to practices far beyond call centers and apparel manufacturing. In fact, you might be surprised at the industries that rely on outsourcing now (Divine, 2010). This paper will examine the effects that outsourcing has already had on business, as well as look a little bit into the future to see what it holds for us down the road. It will focus on how it has affected our economy and society as a whole, as well as the individual organizations and their employees. There are both positive and negative impacts of this way of doing business that need to be realized and accounted for in order for the economy and American business to remain strong. We will reflect...

...identify specific audit procedures. After his meeting with Smith Company’s new management and predecessor auditor, he is now made aware of possible fraud in the financial statements. With this knowledge, he is now responsible to take steps to identify the errors due to fraud in the financial statements. Initially, Reed and his audit team should assess the risks within Smith Company such as the motives and where opportunities exist to commit fraud.

During the course of the audit, they should plan and develop tests that account for the risks assessed. As with any audit, Reed, CPA and his staff must “conduct the audit with due professional care and an attitude of professional skepticism.” (Boynton & Johnson. 2006, p. 58) B.

... Lastly, I will conclude the extent to which I feel my leadership abilities are consistent with transformative leadership principles, as well as how these abilities will help me in the future. I will also discuss how I might strengthen said abilities in the present. Occupational Background I entered the workplace by the age of fourteen. I managed to get a job bussing tables at a supper club on the lake. I continued working in restaurants until the age of nineteen, moving up the ladder from busser, to hostess, and eventually settling on bartending. I liked restaurant work, for the most part. Truth be told, it was the money that kept me in the field. My experience was so narrow, that I had a hard time getting out of it. Management at this point in my life was never something that interested me; I was content just doing my job. I was immature, and did not have enough responsibility. I had a lot of terrible managers in this line of work, and I attribute that to the many reasons I wanted to get out of the hospitality industry. My ambivalence towards careers changed when I eventually enrolled in the local community college, University of Wisconsin Washington County. By this time I was twenty-one years old, with the hopes of pursuing a bachelor’s degree in Nursing. I was strongly motivated to succeed at this point in my life, and was...
