Put yourself in the position of the manager running the electronic circuit operation in problem 7, and summarize your interpretation of the results of these analyses. Expand on your interpretation with response on one or a few of the following:

In problem 7, you can see based on the average chart that as the sample size increases, the voltage of the circuits are gravitating towards the center line of the chart. The center line of the chart “is the average quality characteristic being measured” when considering a process control example such as the one we see in problem 7 (193). Throughout the text, it is explained that as you reach higher above or lower below the center line, the characteristic that is being measured is either getting closer to exceeding “the maximum acceptable random variation,” or upper control limit, or getting closer to exceeding the “minimum acceptable random variation,” or lower control limit “when a state of control exists” (193). In the case of problem 7’s average and range chart’s, we see that the voltage of the circuits are in fact hovering closer towards the center line as both sample size’s increase, meaning that the process control characteristic is in fact limiting the amount of variation or defects within the process. Schroeder defines process capability as “the ability of the process to meet or exceed the technical specifications obtained from customers,” or in other words, the processes ability to ensure that “defective outputs” are either being limited to a certain degree or not produced at all (198). Based on the aforementioned average and range chart’s from problem 7 in the text, it is clear that the producer of electronic circuits in the problem was in fact able to use the process control in place to meet specifications despite his or her decision to use process control by variables…...

Op-Amps

...current can flow into the op-amp. This is due to the grounding at the non-inverting terminal and result in the 0V in the inverting terminal. During the experiment, one of the procedures is to use the dc offset to make sure no dc voltage is in Vin. This is because the input offset voltage is not zero or another word, the supplied voltage work together with AC and DC. Hence, the dc input voltage will be integrated and the output voltage starts to drift. Part 4.6 An op-amp without a feedback resistance is original a difference amplifier. The difference op-amp produces the algebraic difference between the two input signals. Few cases can be done in the difference op-amp. Example like the two input voltage have the same magnitude and the output voltage will be zero which will be the most common. There are no amplification take places when all the external resistors value is the same. Hence, the amplification of the difference op-amp is depends on the ratio of the resistor value. V+ V- B A The output voltage equation can be derived using super position theorem and voltage divider. At first, we will ground the V2 causing the non-inverting terminal and inverting terminal to be zero volt. Hence, at node A Vo1=-R2R1V1 When V1 is grounded, V+=R2R1+R2V2 V+=V- Vo2=1+R2R1V- Vo2=(1+R2R1)R2R1+R2V2 V02=R2R1V2 By superposition theorem Vo=Vo1+Vo2 Vo=-R2R1V1+R2R1V2 Vo=R2R1(V2-V1) Part 4.1 During the experiment, one of the simplest inverting op-amp was build.

...Bottlenecks in a Process Johnson OPS/571 March 17, 2013 Bottlenecks in a Process Information gathered during week one of class was helpful in identifying bottlenecks on the process. Recognizing the bottlenecks that will hinder an individual from achieving daily goals can be a tool to identify ways to manage time better. The Goldratt’s theory of constraint is a dependable theory to identify and successfully handle bottlenecks. Identify Bottlenecks in the Process According to "Theory of Constraints" (2013), “TOC is systemic and strives to identify constraints to system success and to effect the changes necessary to remove them” (Theory of Constraints). The purpose of the process is to manage time wiser so daily goals will be achieved. When time is not manageable an individual will believe there is not enough time within a day to accomplish tasks. The bottlenecks that will hinder accomplishing daily goals would be watching television too much, spending too much time on curricular activities, not creating a “To Do” list, lack of sleep, and exercise. The main bottleneck is not using time wisely to accomplish daily goals successfully. In the Goldratt’s theory of constraints, logical thinking process is one way to help individuals to deal with bottlenecks in a process. According to "Theory of Constraints" (2013), “the thinking process assists with working through the change process by identifying the following: what to change, what to change to, and how to......

Boeing building a plane First thoughts are that Boeing fits almost all of the requirements for continuous flow; low flexibility, one product, very high capital investment, and low skilled labor with skilled overseers. Work would proceed in a fixed sequence of assembly steps, and the process connects all activities in an inflexible process. This process has high capital investment and only produces a minimum amount of product, one. The only reservation I have about this is that the production volume is low.

Don’t forget … you might see these questions again! Directions: Please read the following scenario, then answer the questions that follow.                                                                                                                                          “Managing a Ski Shop” Your best friend’s sister and brother-in-law run the local ski shop near campus in your college town, but they have recently bought another type of business in another town. They want you and your friend to take over managing the ski shop. If you run it successfully, you and your friend will gradually be given substantial equity in the shop and eventually would own the whole business. So far, the shop has been only marginally profitable. Although the shop carries ski equipment and ski clothing, it has habitually run out of both during the peak skiing season. Extra merchandise hastily ordered to meet the demand has often arrived so late that it could not be sold until the next season, if at all. In addition, the shop does very little business from March through August. Due to a dispute over the size and prominence of the outside sign displaying the shop’s......

...Latoya Harrell Cathy Whitfield Business Ethics-MGMT 368 13th January 2015 Kohlberg’s Scale On Kohlberg’s scale, I consider myself to be falling under the fifth stage of the third categorization. The third level which is post conventional morality has two stages, which is stage five which is social contracts and Individual rights and stage six: universal principles. I consider myself to be in stage five. This stage is concerned with a person’s ability to embrace and recognize the reason why differences exist in people’s values, beliefs, opinions and other inclinations of others. The level also maintains and recognizes the importance of the rule of law in maintaining order in the society (Ashford & Lortie, 2010). Kohlberg came up with a scale which he used to explain the learning of morality and the subsequent development of morality among the children and even adults. In an attempt to explain the process of morality development, he established the scale which is mainly based on learning of what is moral and what is not moral, with no regard to the actions of people. Kohlberg’s scale is divided into three main levels and each of the three levels has two stages of the process. The first level is the pre-conventional level. This level has stage one and stage two. Stage one is on obedience and punishment. Under this stage, both adults and children perceive rules as absolute and rigid. Total obedience of the rules is not a choice since it means avoidance of punishment. Stage......

De SEH is er namelijk op gericht om patiënten medische hulp te verlenen bij trauma’s en acute aandoeningen. De SEH is daarmee een onderdeel van een keten van acute zorg, waar ook verloskundigen, huisartsen, ambulance-diensten, meldkamers en mobiele medische teams deel aan nemen. Vanwege de acute zorgvraag van patiënten op de SEH, dient een SEH tijdige en efficiënte zorg te leveren, terwijl zij juist ook nog belast worden met overbezette, stressvolle en uitdagende situaties (Ben-Assuli, 2014). Medewerkers op de SEH kunnen hierdoor een andere informatie- en registratiebehoefte hebben dan medewerkers die op reguliere verpleegafdelingen werken (Ayatollahi et al., 2013). De patiëntenpopulatie van de SEH is namelijk niet beperkt tot ziekteverschijnselen van één specialisme, maar de zorgvraag is juist zeer divers en specialisme overstijgend. De spoedeisende hulp afdeling vereist hierdoor ook een goede samenwerking met veel individuen, zoals het......

Introduction The article “Are vulnerable workers really protected in New Zealand?” is written by two authors namely, Danae Anderson, researcher at Work research Institute, Auckland University of Technology, NZ and Rupert Tipples, Associate Professor of Employment Relations in Faculty of Commerce at Lincoln University, Christchurch, New Zealand and is published in New Zealand Journal of Employment Relations, 39 (1): 52-67. This article is concentrated on exploring the working condition of international migrant workers and pacific workers in primary sectors and are categorised as vulnerable migrants using Sargeant and Tucker’s 2009 framework. The writers have claimed that though protective measures have been adopted to defend the vulnerability of the workers, the result is still speech making only. The article has clearly identified the research topic and used secondary sources of the information to address the research questions. The article has been successful in raising the concerns of vulnerable workers in primary sectors such as exploitation at work, underpayment, employment dependency, visa conditions, lacking of formal written contracts for employment likewise, the article has been able to pull the attention of the concerned authorities to work and rethink to promulgate the......

Riordan’s mission statement states that it’s focus is to “Six Sigma, leading edge R&D and exceeding ISO standards” (Riordan Mfg. Internet, home page, 2014). Riordan’s fan manufacturing operation is located in Hangzhou, China. Team D will evaluate the Riordan’s fan manufacturing supply chain design and perform a comprehensive evaluation of the operational effectiveness of the supply chain. Manufacturing Strategy Riordan’s Intranet states, that the Hangzhou plant bases its forecasts by “taking the average of sales for the last three years and extrapolating it into the next year” (Riordan, Operations, Hangzhou, China, 2014, p. 1 para 4). Riordan’s use of this approach has lead to a 93 percent on-time delivery rate. Team D believes that the information regarding Riordan’s manufacturing strategy, taken from the firm’s intranet website is an indication that it employs a “Stable Workforce-Variable Work Hours” production planning strategy. This strategy varies the number of hours worked through flexible work schedules or overtime to match the production quantities to orders” (Jacobs & Chase, 2011, pg. 534). It helps assure that the workforce has continuity which helps with employee morale. It is extremely important for employees to feel secure in their work environment.

This vehicle, the Buick Envision, adds another luxury crossover to the lineup. The United Auto Workers union, saying that the decision does not represent the many people who worked to save General Motors during its bankruptcy, quickly criticized this. GM responded by saying that the Envision is already in production in China and it did not make economic sense to open another manufacturing facility. If GM can battle the potentially negative public opinion of the Envision in the United States, the new crossover could fit a niche spot for the company and build market share.

Kentucky Fried Chicken is one of the leading U.S. fast food chains currently in China. There are several factors that have contributed to KFC’s rapid expansion and success in China. The story of KFC in China is one of great success on an economic level, as well as a great example of international business. There are many factors behind KFC’s success in China which include, five competitive advantages: infusing a Western brand with Chinese characteristics, expanding rapidly, developing a logistics network, training employees in service, and focusing on ownership rather than franchising. KFC is part of the Yum! Brand, which also owns Pizza Hut and Taco Bell. KFC China’s success in the international market has all been due to its five competitive advantages. The first of these advantages is infusing a Western brand with Chinese characteristics. KFC China makes sure that even though it is a US chain and restaurant it has worked hard to assimilate into the Chinese culture. They have done this by offering a variety of menu choices that cater to the local cuisine. They have also expanded their kitchens and their workforce to be able to produce and accommodate for the additional menu options. Extended families are a big part of Chinese culture; KFC China has acknowledged this by......
