The Tragedy of Mileva Maric Einstein - Einsteins First Wife Essay exa
The Tragedy of Mileva Maric Einstein - Einstein's First Wife A hundred years ago, a young married couple sat at a kitchen table talking over the items of the day while their young boy sat listening earnestly. He had heard the debate every night, and while there were no raised voices, their discussion was intense. It was a subject about which his parents were most passionate - the electrodynamics of moving bodies in the universe. The couple were of equal intelligence and fortitude, working together on a theory that few people can comprehend even to this day. Mileva Maric Einstein was considered to be the intellectual equal of her husband Albert, but somehow went unrecognized for her contributions to the 1905 Papers, which included the Special Theory of Relativity. The stronger force of these two bodies would be propelled into the archives of scientific history, while the other would be left to die alone, virtually unknown. Mrs. Einstein was robbed. She deserved to be recognized for at least a collaborative effort, but it was not to be. The role which society had accorded her and plain, bad luck would prove to be responsible for the life of this great mathematician and scientist, gone unnoticed. Mileva "was born in Hungary in 1875, with a hip deformity and a good mind" (Storey 31). Although women did not usually pursue science degrees, she had won top marks in her class for math and physics, and was sent on to the Swiss Federal Institute of Technology in Zurich the same year as Einstein (Grenier B05). She was one of five in their class; Mileva and Albert both specialized in theoretical physics. Mileva attended classes and took notes for both of them. They studied for every class together.

Grandpaââ¬â¢s Illness Essays -- Personal Narrative Writing
Grandpaââ¬â¢s Illness As usual I woke up to the sound of my father pounding on my bedroom door, hollering, ââ¬Å"Get up! Get on your feet! Youââ¬â¢re burning daylight!â⬠I met my brother in the hallway, and we took our time making it down the stairs, still waking up from last nightââ¬â¢s sleep. As we made our way to the kitchen, I thought about what to have for breakfast: fried eggs, pancakes, an omelet, or maybe just some cereal. I started to get hungry. As usual, mom and dad were waiting in the kitchen. Mom was ready to cook whatever we could all agree on, and dad was sitting at the table watching the news. The conversation went as usual, ââ¬Å"Good morning.â⬠ââ¬Å"How are you today?â⬠Then the phone rang and Dad answered it. It was hard to tell what the conversation was about, it did not last long and Dad didnââ¬â¢t say much. When he hung up he was quiet. Then Mom asked, ââ¬Å"Who was that, honey?â⬠Blunt and to the point he said, ââ¬Å"Grandma,â⬠(his mom) ââ¬Å"Grandpa got sick last night.â⬠Suddenly I was not hungry any more. ââ¬Å"Whatââ¬â¢s that mean?â⬠Mom asked, taking the words right out of my mouth. Dad did not really know. All Grandma said was that Grandpa got up in the night, went to the bathroom, and then yelled for help before collapsing. She called 911 and an ambulance came and got him. From the hospital in Spirit Lake he was life-flighted to Sioux Falls. During the drive to Sioux Falls all I could think about were all the happy times spent at Grandmaââ¬â¢s and Grandpaââ¬â¢s lake house on West Okoboji. I thought about how Grandpa would entertain all of his grandkids in the speed boat and then take us back to the house for a beer. All that was changing, there would probably be no more speed boating and no more beer. When my family and I arrived at the hospital we ru... ... a smile came across his face, a smile that for three weeks, I thought I was never going to see again. Unfortunately, his struggle with alcohol was just beginning. To this day he attends AA meetings and is doing great. The days of speed boating have continued, but there is no more beer drinking. For his grandkids, not much has really changed, except Grandpaââ¬â¢s health has improved. He has more energy and a better outlook on life. I think the experience helped him realize that his motto ââ¬Å"Quality over Quantityâ⬠is not concrete and that there needs to be a balance between the two. We cannot get by on just the pleasures in life because it isnââ¬â¢t fair to our loved ones we have to compromise and make sacrifices in order to keep our health. Works Cited Quoteland.com.

Social Conflict in Public Schools
Big American government is widely perceived as the foundation of social order in our country, yet it is, as some would say the single greatest source of disorder. Political power constantly tempts those who control it to enforce conformity with their own preferences of Education, and Religion, As seen in our country and many parts of the world, citizens will evade enforcers if they can but when necessary will fight back. Our public schools can also be looked at through the structural-functional theory In an article by Jim Powell entitled ââ¬Å" Public Schools and Social Conflictsâ⬠he discusses the many conflicts in our public schools are primarily the product of our governments deliberate doings. In the early 1840ââ¬â¢s for instance, Protestant dominated public schools were made compulsory for the newly landed immigrant Irish and southern European Catholics. Conflict arose when the Catholics resented having to pay taxes for Protestant schools where courtesy of another government bodies mandate Protestant values were to be taught there as well. The Catholics proceeded to establish their own system of ââ¬Å"parochialâ⬠schools, however the age old practice of collecting public school taxes still exists no matter where the student chooses to be educated. Religion is another public school related conflict that Jim Powell discusses. Here he discusses the most famous social conflicts of public school history, the issue of whether schools should teach the biblical story of how the world was created. The ââ¬Å"Butler Actâ⬠which made it illegal for any public school to teach a theory that denied the biblical story was how the conflict began. After a series of trials, debates, court and governmental interventions, the conflict still exists. Our public schools can also be viewed under he structural-functional theory. The various cogs of our public schools were probably intended to work together coherently to promote solidarity and stability as the structural-functional theory would suggest. The compulsory mandate of schooling for every child was probably intended to keep the majority of the new population educated thus increasing their productivity in a very young country. Many sociologist like Karl Marx would see this as an opportunity to not only live with the interpreted word but to constantly enact changes to conform with the needs of the current population thus maintaining the desired solidarity and stability . This type of sociologist would suggest that one only had to pay school taxes if the child used the public school system. In our day and age it would seem fair to the children who are home schooled or for that matter senior citizens and families with no children using the public school system, so the burden lay only on the benefit users. Infact it is the main point of discussion whenever a school budget or election comes up in many a town. On the issue of religion, this type of sociologist one that values preserving the desired solidarity and stability would suggest that issues of the religious nature not be discussed at all and that religious students should have a silent moment of prayer should the need arise, thus lending value to the now popular ââ¬Å"separation of church and stateâ⬠. There are many manifest functions of the public school system that can be The public system is a solid, affordable and consistent source of education for the vast majority of the population and being government funded has its regulations and systems in place. Freedoms that Americans have gotten used to are valued as well. Lack of regulation can have itââ¬â¢s own set of problems as was exemplified in the current ââ¬Å"Financial meltdownâ⬠. Latent functions could also be seen in the public school system as is evident in the fact that public colleges function as a ââ¬Å"marriage marketâ⬠. Here young people of similar socio-economic backgrounds meet and perhaps form lifelong relationships. As was evident in the case of the recent Royal wedding where in Kate Middleton, the daughter of a wealthy businessman was enrolled in a prestigious university thus enhancing her ability to possibly meet a partner of similar stature who in this instance happened to be Prince William. Many a relationships have begun this way and although very rarely acknowledged is a unrecognized and unintended consequence of the public school experience. The public school system does affect American cultural values namely :Equal opportunity along with Individual achievement and Personal success. The public school system does for the most part offer equal opportunity to everyone who wishes to pursue this or her individual dreams. With all the checks in the system it gets next to impossible for any given public education system to waiver making allowances when deemed fit and holding firm when necessary. Individual achievement and personal success are cultural values very connected to the value of equal opportunity. In America, more so than in many other parts of the world is truly the ââ¬Å"Land of Opportunityâ⬠. The sky is the limit if one has the desire and dares to dream. With the theoretical perspective in mind it is imperative that American cultural values will change as time progresses. There are constant changes that the public school arena is exposed to: The changing mix of certain ethnic populations in a given environment has given rise to a need for educators with English as a Second language backgrounds. Another area where cultural values will change are in the Special Education arena where with the growing classifications and need to integrate young Special Ed students educators will have to make adjustments to the way the whole population is taught so as to promote solidarity and stability as the structural-functional theory would suggest.

English Literature Essay
Literature (from Latin litterae (plural); letter) is the art of written work, and is not confined to published sources (although, under some circumstances, unpublished sources can also be exempt). The word literature literally means ââ¬Å"things made from lettersâ⬠and the pars pro toto term ââ¬Å"lettersâ⬠is sometimes used to signify ââ¬Å"literature,â⬠as in the figures of speech ââ¬Å"arts and lettersâ⬠and ââ¬Å"man of letters.â⬠The four major classifications of literature are poetry, prose, fiction, and non-fiction. What in Philippine Literature? Philippine literature is the literature associated with the Philippines and includes the legends of prehistory, and the colonial legacy of the Philippines. Most of the notable literature of the Philippines was written during the Spanish period and the first half of the 20th century in Spanish language. Philippine literature is written in Spanish, English, Tagalog, and/or other native Philippine languages. As a Filipino, What is the importance of Literature? Literature serves as an enormous information base. Research works by famous inventors and literary works by notable scientists often narrate stories of their groundbreaking discoveries and inferences. Ongoing developments in the fields of science and technology are documented so that the world can know about them. Several ancient scriptures relating stories of human evolution and narratives of human life in those times, have been of tremendous help to mankind. Thus, literature has always served as an authentic source of information from all around the world. What environmental education goals and features? Philippines is not an exemption in letting us feel the harsh realities of these environmental threats and challenges. With all the ever increasing demands created by the environmental problems accompanied by social, political and technological changes happening, the education sector is faced with challenges and is expected to initiate changes in the curriculum and give more attention to environmental education. The curriculum should be geared towards the provision of knowledge, skills and values that will helpà the learners cope and adapt to these changes. The goal of environmental education is to develop an environmentally literate and responsible citizenry who will ensure the protection and the improvement of the environment, and bring about sustainability, social equity and economic efficiency in the use of the countryââ¬â¢s natural resources. Because of the existing environmental problems we are into and the thrust for sustainability, the protection and improvement of the environment have become imperative educational goals. It is also envisioned that within the next decade, a great majority of Filipinos will be imbued with a sense of responsibility to care for, protect for, and enhance environmental quality that is conducive to their wellbeing and supportive of the nationââ¬â¢s economic development.

Cola Wars Continue: Coke and Pepsi in 2010
Cola Wars Continue: Coke and Pepsi in 2010 A case discussion note January 17, 2012 1. Historically, why has the soft drink industry been so profitable? Historically, the soft carbonated soft drink (CSD) industry has been valued at $74 billion in the United States. In order to understand the reasons why the industry has been hugely profitable despite the ââ¬ËCola Warsââ¬â¢, an examination of the CSD industry with Porterââ¬â¢s five forces analysis will be conducted. As market leaders, the analysis will be centred on both Coke and Pepsi (hereafter ââ¬Å"C&Pâ⬠). Threat of new competition: Barriers to entry in the CSD industry are extremely high and there are various factors to support this. Firstly, both C&P spend gargantuan amounts of funding of advertisement. According to Exhibit 8, in 2009 alone, both C&P spent $234 million and $145 million respectively in advertising expenditure. Therefore, while the actual initial capital investment needed to start up a CSD company is relatively economic, the amount required by new entrants to continually push their brand and gain visibility is extremely high. Due to these extreme levels of expenditure on marketing and brand awareness, the two cola companies have accrued exceedingly high levels of brand equity and consumer loyalty worldwide. As such, even with sufficient funds for start-up and subsequent advertising, new entrants are unlikely to sway persisting consumer tastes. Because of the sheer scale of both CSD companies, both C&P have pre-existing contracts with their bottlers, thus limiting their bottlersââ¬â¢ ability to produce similar products with rival brands. Additionally, through the use of extensive consolidation through the use of acquisitions and re-franchising of their bottlers, both C&P have made it essentially impossible for new entrants to find bottlers for the distribution of their drinks. In the event that the new entrants decide to build their own bottling plants (which is quoted to potentially cost hundreds of millions in the case), they would only find themselves facing insurmountable fixed start-up costs in addition to the ridiculous amount they have to spend on marketing. Even if new entrants somehow found a way to produce and market their drinks, the incumbentsââ¬â¢ (C&P) far-reaching networks would make it impossible for them to secure any form of distribution channels. Shelf spaces in supermarkets were dominated by C&P because supermarkets were given a cut of the profit generated from the sales of their products. These cuts accumulate to a significant amount of profit-generation for the retailers. Additionally, combined, C&P owned 89% of national pouring rights. The fact that the incumbents had exclusivity in both supermarkets, fountain outlets, and other forms of retail channels would make it almost impossible for new entrants to distribute their products. Bargaining power of consumers: Historically, the two main customers of soft drink producers were supermarkets (29. 1% of distribution) and fountain outlets (23. 1%). In general, retail outlets have been unsuccessful in asserting much bargaining power over the industry. In part due to the level of fragmentation as well as their reliance on C&P as drivers of customer traffic. Longstanding contracts and acquisition of fountain outlets also serve to weaken consumerââ¬â¢s bargaining power. Bargaining power of suppliers: Major suppliers for C&P provided commodities in the form of cans, sugar, bottles, etc. These products were highly homogenous and could be substituted easily. The aluminium can industry, in particular, depended on firms like C&P because they were majority buyers. Due to such dependence, suppliers asserted little or no bargaining power over the industry. Intensity of competitive rivalry: Even though C&P are essentially a duopoly in the CSD industry, competition between the two have traditionally centred on marketing efforts like advertising, new products, and promotions rather than pricing. Their rivalry, historically, was also in a market with consistent growth. As such, profits were not adversely affected even though their rivalry was highly documented and publicised. Threat of substitutes: There are a number of alternative substitutes for soft drinks and these include beer, bottled water, tap water, juices, tea, coffee, wine, powdered drinks, milk, and distilled spirits. Yet, according to Exhibit 1, Americans, historically, consistently drank more CSDs than any other beverage. As such, the threat of substitutes affecting C&Pââ¬â¢s profitability was limited. To further nullify the effects of substitutes, they also produced and promoted their own range of substitutes to reduce potential losses. 2. Compare the conomics of the concentrate business with that of the bottling business. Why is the profitability so different? Using data from Exhibit 4, we are able to see that the operating income of a concentrate producer is 32% of its net sales while that of a bottler is only 8%. The reason the bottling business earns significantly lesser than its concentrate counterpart can be attributed to two main factors ââ¬â significantly higher cost of goods sold (COGS) and the existence of selling and delivery expense. We see that the COGS of a bottler are at 58%, much higher than the concentrate producerââ¬â¢s 22%. The reason for this difference is predominantly due to Master Bottler Contracts established to allow for a certain level of ââ¬Å"price fixingâ⬠on the concentrate producersââ¬â¢ part. Additionally, as mentioned previously, raw materials for concentrate producers are abundant and homogenous; hence COGS for them will be significantly lower. Also, the bottler is in charge of selling and delivery, and hence incurs an 18% selling and delivery expense while there is no such expense on the concentrate producerââ¬â¢s part. These reasons explain why the concentrate business has a more profitable business model than the bottling business. . How has the growing popularity of non-carbonated soft drinks influenced the industry? Non-carbonated soft drinks have been gaining popularity in the past decade, increasing from 13% in 2000 to 17% in 2009. This growing popularity has resulted in the generation of both local and global strategies by CSD firms unwilling to lose out on the budding market. In order to capitalize on the opportunity, both C&P greatly expanded their lines of beverages to include sports drinks like Gatorade and tea-based drinks like Lipton. Majority of drinks introduced during this time were non-CSDs. Besides creating new products, Coke also aggressively gained market share through acquisitions and extending their fountain services to include coffee and tea. The non-CSD opportunities globally were also aggressively pursued by companies like C&P. To gain localized expertise, however, the soft drink companies did not merely think to introduce new products into foreign markets. Instead, they resorted to acquiring the respective market leading, non-CSD companies in the countries they chose to invest in. The companies of choice were usually major fruit juice producers. Beyond takeovers, C&P also tried their hands at innovation and localization of beverages. These mainly came in the form of integration of local drinks (e. g. blended green tea with Sprite) or utilization of local ingredients in the production of new drinks (e. g. beverages with Chinese herbs). The emergence and rapidly growing popularity of the non-CSD has garnered much retaliation from major players in the CSD industry. In order to get their share of the pie, they have formulated expansion strategies both locally and globally which seem to center around acquisition.
Diaspora and Health?
Traditional Medicine and Culture in a Mexican Migrant Community in 2008. ââ¬Å"As members of the Mexican Diaspora acculturate/ assimilate to life in the united States they gain skills that help them improve their socioeconomic statusâ⬠(Walden, 2008), but their health deteriorates as their culture is lost. The importance of cultural competence in nursing includes recognition of how the deterioration occurs and practice the principles of healthcare ethics through autonomy, beneficence, malefaction, and justice while practicing healthcare for this population (Demonic, 2015). Summary of ArticleThe journal article being reviewed for this paper is a doctoral dissertation that studies the changes in overall health of the Mexican Diaspora after migrating to the United States. The writer presents a specific study group of migrant Mexican women in Georgia, as well as some general Mexican immigrant information from other sources, including California. The objective seems to be to educate the healthcare providers on the overall health of the migrants related to their choices of lifestyles. The two choices being to remain in a low- income but migrant population, or to assimilate and acculturate into theAmerican populations. The primary research site for this study is in Athens, Georgia and takes place in a Spanish-speaking low-income neighborhood named ââ¬Å"Los Duplexâ⬠and it focuses on women. The economy in Athens depends on the University students and much of the employment is with the service industry. The neighborhoods, or barrios, are small and isolated on the outskirts of town. Los Duplex has a community center that is nick named La Cellulite or Little School. The community center offers classes in English, parenting, nutrition, as well as after-school activities and homework help for kids.The community center has ââ¬Å"â⬠¦ Eloped cultivate a sense of community among the residents, who come from many different parts of Mexicoâ⬠(Wieldiest, 200 8). After describing how the study group was chosen and what all the details of the study were, Wieldiest continues on with the explanation of the difference in health the Mexican migrants face by either staying true to their culture or assimilating to their host culture. So many migrants come to America with the intention to work and return to their country and family, but when they start working and acculturating many of them choose to stay.Wieldiest explains that Mexican women are well-educated as part of their up- ringing, about the natural medicines. The native plants are used for all purposes of health. The two most popular medicinal plants are chamomile and peppermint. Not only the indigenous plants, but the whole foods that the Mexican woman prepare are fresh and have more protein, vitamin A, C, folic acid, and calcium than what the American born Mexican women and the women of European descent prepare. Wieldiest explains that this is because Mexican women's definition of a g ood diet includes fruits, vegetables, and plenty of water.The women pointed out that mindful eating is important, only eating what the body needs, and eating outside of the home, ââ¬Å"especially in the street' leads to poor habits and sickness. Mexican women that were used in this study pointed out that staying calm, avoiding anger, staying active, caring for oneself and others, and getting enough sleep were also important, along with healthy eating. The migrants that came to America, but sought out their one culture to live amongst stayed active physically and socially.The types of employment available were manual labor jobs, agriculture, factory, restaurant work; all of which are active jobs where the errors had less chance to become sedentary and obese. By sticking to their own neighborhoods and social groups they stayed happy and active. Medicine and medical care is taken care of in the homes by the Mexican woman using natural remedies and herbs. Wieldiest learned that Mexican families expect the women to learn about the medicine and how to use them.The fresh herbs are preferred over the dry herbs that are purchased in the stores in America, but the plants don't grow well in the America due to the weather changes. A most popular herb is chamomile to be used as a tea infusion. This is useful for Castro-intestinal problems because it has anti- spasmodic and anti-inflammatory properties. The women shared 42 different herbal remedies during the interviews. Two popular over-the-counter products the women used were Ethylene for headaches and Vic's Vapor Rub for congestion.The most common prescription medications include anti- fungal, high blood pressure, diabetes, and antibiotic medications. Application to Practice The Mexican Diaspora who remain the healthiest tend to stick to their own culture when they migrate, however the women of this study recognize the deed for professional medical treatment. Going to the doctor is reserved for the most serious sickness es that do not respond to home remedies. For this reason the migrants interviewed for this study told about the free clinics, women's clinics, and public hospitals in Los Duplex area.Some Of the immigrants have insurance and some participate in low-income assistance programs. The hospitals in Athens have a well-funded low-income assistance program that even covers UN-documented immigrants. The hospitals and clinics used for this study had interpreters and bi-lingual healthcare revisers. The hospitals employ social workers to help enroll the children in programs like Medicaid, Women Infants and Children (WICK), and a local program in Georgia called ââ¬Å"Peachier. â⬠Healthcare barriers cited by Wieldiest that were reported by the Mexican women of Los Duplex include those that most healthcare workers.High cost of healthcare, no health insurance, poor English skills, and lack of transportation are the main barriers. In chapter 25 of Advanced Practice Nursing there is a definitio n for Principles of Healthcare Ethics: Ethical principles are universal rules of induct that identify which kinds of actions, intentions and motives are valued (peg 554). This is only a fraction of the definition, yet it is so profound. The women of this study value community, love, family, and healthy living. They are raised and taught as children to take care, nurture, grow, and heal themselves and their families and friends.Mexican women are autonomous, they choose for themselves how to live healthy. They are beneficent by demonstrating kindness and helping others. The health care system in place in the Los Duplex area should stay maleficent, avoid causing patients arm. If the women have exhausted the home remedies prior to taking their friends or family to the hospital they expect to be cared for, not harmed. ââ¬Å"Justice is the obligation to be fairâ⬠¦ â⬠And this is another expectation when people go to a healthcare facility (Barker, 2013. Peg 554-556). Nursing inte rventions should be in put in place for each barrier presented by a patient.An example of a nursing intervention for a family in the Los Duplex would be to have all forms in Spanish and English along with some type of interpreter offered. While admitting a Mexican migrant patient into a hospital r clinic, attention should be given to the culturally common home remedies. Fifth intake nurse is educated in the culture and now the patient has hypertension, then what other natural herbs or fruits and vegetables is the patient taking in that could be contra-indicated with a medication, and therefore rendering the high blood pressure medication that was previously prescribed, as useless.Nurses hold the power when it comes to connecting with patients, they are the driving force of the care continuum. The more the nurses know about the community culture and the patient culture, the better are can be offered and healthy outcomes achieved. Conclusion The study that was used for this dissertati on touched on key concepts of cultural sensitivity in communicating with Mexican Diaspora, especially the women who care for their families and friends.As a migrant culture, the Mexicans are healthier if left to take care of themselves with their home remedies of healthy herbs, healthy diets, healthy mental status, and healthy social groups. As health care providers, it is important to maintain an ethical health care environment and respect the autonomy of the Mexican women ascribed in this paper. They treat their families and friends with beneficence and the health care providers need to remain maleficent when assisting the patients with their illnesses.Meanwhile, the organization of healthcare systems need to treat every patient justly, address the language barriers, the financial barriers, and insurance barriers with fairness and equality. The study of Los Duplex was a small group of Mexican migrants, and like other world cultures, there are many more cultural differences. The mo st important point is to respect the patient, listen and do the best job possible to et the needs of the mother or father or child sitting in the chair in need of medical attention, no matter what culture they are from.

Case Study Rolls Royce Economics Essay
Case Study Rolls Royce Economics Essay By instructing that parts and sub-assemblies are only produced to meet that demand MRP seeks to meet projected customer demand. Using the bill of materials to calculate how many are needed and when they must be made MRP back schedules demand for part and sub-assemblies. This is how MRP connects customer demand with the internal and external supply network. Although JIT planning and control has similar objectives. Derived from end-customer demand Pull scheduling parts only move in response to matched and synchronised signals (Slack, 2004). MRP is driven by the MPS that identifies future end-item demand. Using a computer to calculate how many of, and when, each part should be made a fixed lead-time environment is modelled. Its output is of time-phased environment plans that are centrally calculated and coordinated. Regardless of whether the next process can take or actually need the part at that time it is made in response to central instructions. The authority of MRP is undermine and make the plans unworkable at the shop floor level due to day-to-day disturbances, such as quality problems and inaccurate stock records. While MRP is excellent at planning, it is weak at control (Slack, 2004). MRP II is more precise than MRP because it instigates production of a variety of components, releases orders and offsets inventory reductions. ââ¬Å"MRP II grasps the final product by its parts, orders their delivery to operators, keeps track of inventory positions in all stages of production, and determines what is needed to add to existing inventoriesâ⬠(Karmarkar, 1989). Through such products as SAP and Oracle, MRP II has led to additional advancements such as ERP. An ERP system consists of a suite of software modules, where each module is usually responsible for a separate business function. Its functionality has increased by new software capabilities; however the core planning and control assumptions that underline these packages have developed less rapidly (Steven son, 2005). Case Study: Rolls Royce One of the worldââ¬â¢s largest manufacturers of the gas turbines is Rolls Royce. Their products are used to in civil aircraft, military aircraft, fast ships and power generation in addition to many other uses. Typically each product has around 25,000 parts as they are exceptionally complex products, and have hundreds of assemblies and sub-assemblies. Moreover, their production is equally complex with thousands of work centres in many different locations and over 600 external suppliers. Rolls Royce was one of the earliest users of computers to help with the task due to the complexity of planning and controlling their manufacture. Conventionally the company developed its won systems and software. The company then decided on implementing a standard ERP system, which was supplied by SAP and was their best selling R/3 product. This system offered a number of advantages over the approach previously used within the company. Significantly, it was an of f-the-shelf system that would force the company to implement a standardised and disciplined approach. Ultimately the entire organisation would use a singular modular database that would reduce duplication and errors. ââ¬Å"There was an extensive data clean up to ensure accuracy and integrity of existing information, and all existing processes were reviewed and standardisedà ¢Ã¢â ¬Ã ¦.Within operations we have already seen a significant reduction in inventory, improved customer service, and substantially improved business information and controls.â⬠(Slack, 2004)
