Forbes International Top Ten Research Paper Example | Topics and Well Written Essays - 750 words

Forbes International Top Ten - Research Paper Example There are many things that Toyota has done in order to outsell its competition. This report will discuss the strategic plan in depth. According to the Maynard (2008) one of the things that Toyota does is to find a way to build their cars better. Some of what they do is to encourage employees to do exercises that will create a more focused employee. This is part of their strategy to use in training centers to make sure that their employees are focused on what they are attempting to do. They have found that through watching how they make cars and improving this at every level, it has created a better opportunity for them to build cars faster (Maynard, 2008). Dawson and Shirouzu (2011) also state that Toyota is downsizing its board of directors in order to make decisions at the higher levels easier. The plan will also include an expansion to China and India before it is completed (Dawson and Shirouzu, 2011). Akio Toyoda (2011) the new head of Toyota has created a vision for his company that provides what they intend to do in the future. It details their strategic plan and provides important information as to how they see themselves and what they are to do. The information they provide is as follows: â€Å"Toyota will lead the way to the future of mobility (par. 7)†. Toyota will creatively stay ahead of its competition. This area includes finding ways to help people in different types of mobility as well as moving them into the future and they will research â€Å"smart grids† (par. 7) in order to understand how to make their company more ecologically friendly. â€Å"Enriching lives around the world (par. 8).† This statement is their commitment to making automobiles that people want to drive. This provides continuous employment for many people and it provides safe vehicles for those who need them. â€Å"With the safest and most responsible ways of moving people (par. 9).† This statement involves Toyota’s commitment to making sure t hat their vehicles are safe and attractive to the eye. They want people to purchase them because they are emotionally moved to do so as well as providing an automobile that is safe and environmentally friendly. â€Å"Through our commitment to quality, constant innovation (par. 10).† According to Toyoda, this is the â€Å"DNA† of what Toyota is and what they are supposed to do. It means that they are always looking for ways to reinvent themselves so that they can provide vehicles that will respond to the needs of people in the future. â€Å"Respect for the planet (par. 11).† This statement is their commitment to taking the environment into consideration when they make automobiles. They are committed to creating a way to manufacture automobiles that â€Å"minimizes waste† (par. 11). These eleven statements are at the heart of Toyota’s strategic plan according to Toyoda (2011) and they are what they want to work with throughout the next several years. In addition, they have a commitment to their employees to make sure that they are reaching goals that they have set. It is important to Toyota that all employees work to a high level of performance and they expect that their stockholders and others will form positive opinions of what they are doing. They are interested in making sure that the people who work for them take into consideration opinions and thoughts of both their customers and their stakeholders (Toyoda, 2011, par. 12). Toyota also emphasizes

Theories of learning Essay Example for Free

Theories of learning Essay This assignment will address andragogy – a theory of learning. To do this it will focus on the specific areas of andragogy and compare them to other theories of learning. The theory of andragogy has been around for nearly two centuries and the findings are particularly linked to the work of Malcolm Knowles. The judgements will be related to the experiences of students in higher education. The theory of adult learning is a â€Å"dynamic area of research and theory building. † (Merriam, 2008 p2). Malcolm Knowles explains that â€Å"andragogy assumes that the point at which an individual achieves a self concept of essential self-direction is the point at which he psychologically becomes adult. † (As cited by Atherton J. S, 2005 p1). Knowles (1970) sees andragogy as a contrast to pedagogy (the teaching of children) which he says is a â€Å"teacher dominated form of education, long regarded as appropriate for children’s learning, and [andragogy] a learner-centred one, now viewed as particularly relevant for non-traditional adult learners. † (Bartle, 2008 p1). Knowles explains andragogy to be the â€Å"art and science of helping adults learn† (as cited by Bartle, 2008 p1). He also argues that â€Å"adults were self-directed, problem solving learners whose life experience constituted a significant learning resource. Thus instead of the traditional hierarchical relationship between the teacher and pupil, the adult learner participates fully in his or her education, influencing the curriculum and determining learning objectives. †(Bartle, 2008 p1) Knowles’ assumptions are based around five key facts: 1. Self-concept: as a person matures his concept moves from one of being a dependant personality toward one of being a self-directed human being 2. Experience: As a person matures he accumulates a growing reservoir of experience that becomes an increasing resource for learning. 3. Readiness to learn. As a person matures his readiness to learn becomes orientated increasingly to the developmental tasks of his social roles. 4. Orientation to learning. As a person matures his time perspective changes from one of postponed application of knowledge to immediacy of application, and accordingly his orientation toward learning shifts from one of subject- centeredness to one of problem centredness. 5. Motivation to learn: As a person matures the motivation to learn is internal (Knowles 1984:12) (As cited by Smith M. K, 1996; 1999 p1) Each of these assumptions comes under considerable debate. His idea of self-concept implies that all adults move from dependant to self-directed learning and that they need to be responsible for their own decisions. Adults need to be treated as capable of self-direction (Smith M. K, 1996; 1999). Knowles believes that adults should participate in designing their own development tasks and the educator should help to focus on the goals and provide ideas, resources and feedback to guide towards progress (Knowles, 1970). The next point explains the belief that adults learn effectively through â€Å"experimental techniques of education such as discussions and problem solving† (as cited by Smith M. K, 1996; 1999 p3). Sometimes experimental learning in inappropriate, especially when large amounts of new information are necessary and the decision must be made as to what is being learnt before making judgements (Smith M K, 1969; 1999) It could be argued that different experiences could be bias and presumptuous. Knowles third assumption regarding readiness to learn emphasises the place at which the importance of study becomes clear to carry out a particular task. It could be interpreted as adults learn things that are useful rather than intriguing or interesting – do we not learn some things just for sheer pleasure? (Smith M.K, 1969; 1999). It has also been argued by Dewey (1993) that â€Å"literature on reflection (e. g. Boud et al 1985) would support the argument that age and amount of experience makes no educational difference† (cited by Smith M K, 1996;1999). If this is the case then Knowles assumptions on the difference between andragogy and pedagogy are queried. With regard to orientation to learning Knowles sees this as conditioned rather than natural learning (as cited by Smith M. K, 1996; 1999). He states that the educator should ensure the adults desire for growth and anticipated results are clear, personal and realistic. He also expresses that adults are goal orientated in their learning (Knowles 1970). In his final point Knowles (as cited by Bartle, 2008) suggests that as adults the motivation to learn becomes internal, enquiry based and directed by the learner. He also suggests that as adults the relationship between the educator and the learner is one of mutual responsibility where the educator is seen more as a guide or coach. The life experiences of the learner are respected by the educator who becomes â€Å"a colleague who contributes to the learner’s self-esteem and sense of accomplishment† (Knowles, cited by Bartle, 2008 p4). This creates a setting to help the adult realise their full potential and move towards fully independent learning. In comparison to angragogy the constructivist theory of learning, as suggested by Biggs (2003), focuses on the learners knowledge and their approach to learning, suggesting learning is not just about acquiring knowledge but â€Å"as we learn our conceptions of phenomena change and we see the world differently. The acquisition of information in itself does not bring about such a change, but the way we structure the information and think with it does. † (Biggs, 2003 p13) Angagogy relates to Higher Education students as it recognises the great amount of learning that takes place throughout life and in various non-academic settings with the adult learner taking control. Knowles suggests that â€Å"students should be empowered for self-education, determining course content and self evaluation† (Knowles as cited by Bartle, 2008 p4) and prominent adult educators maintain a student-centred classroom by encouraging a problem-solving curriculum inclusive of self-pacing, designed by students, and also offering the opportunity for risk taking. The educator continues to â€Å"raise student consciousness while acknowledging life experience, and building a democratic, flexible, and personally supportive climate. † (Bartle, 2008 p4). In this assignment I have looked at the main areas of andragogy – adult learners being self directed, ready to learn and intrinsically motivated. Andragogy has been compared to pedagogy and constructivism theories and the differences highlighted. The findings have been related to the experiences of students in higher education showing the educators role to remain meaningful but less instructive and the learners learning what they need to know in order to grow. Adult learning is an ever-expanding area of research and theory, challenging ideas and confronting the theories of learning.

Quality management of executive holloware

Quality management of executive holloware 1 Why is quality important to Executive Holloware? Quality is important to Executive Holloware because they are one of the UKs leading suppliers of top-quality holloware. They describe themselves as selling to a top end market. As a result their products are priced high. Executive Holloware say their most important product was a handmade silver-plated Georgian tea set priced at over  £400. It is implied that this is the most expensive product and thats why they thought it was the most important. This could be a misguided opinion. It could have been the companys trademark, the item which made the brand; in this case you could have called it the most important because without it, there was no brand. The entire product range was hand-made and it looks like this was a big part of Executive Hollowares brand image. Holloware is a term that refers to table service items such as sugar bowls, coffee pots, teapots and other metal items that go on a table. Holloware is traditionally constructed to last a long time. It is typically made with thicker walls and more layers of silver-plate than other silverware. [1] 2 What do you understand by the term quality? The ISO9000 system describes Quality as: The degree to which a set of inherent characteristics fulfils requirements[3] The American society for Quality describes Quality as: A subjective term for which each person has his or her own definition[4] In reality the definition of quality depends on your viewpoint. A customer may look at quality in terms of design, how the product performs, or whether it lasts as expected. A producer may look at quality in terms of conformance to requirements and the cost of quality i.e. scrap and profits. A government may see quality in terms of safety or environment. In industry, quality is often measured using values e.g. number of features, reliability, aesthetics etc. The majority of definitions seem to agree that regardless of your viewpoint, there is a set of requirements, whether it is conscious or sub-conscious, for which conformance is the goal. It is important to understand a range of peoples requirements both for a products customer base and within the company in design, manufacturing and other departments. 3 How would you specify quality for executive holloware? A quality product for Executive Holloware is a product that is free from: * Dimensional inaccuracies * Scratches * Bruises The product must be free from defects if a customer is to be proud of presenting it on their dinner table. Customers use the product to give their dinner tables a touch of class and give their guests the impression that no expense has been spared. In terms of the Georgian tea set, the product should be made of a layered silver-plate, other products are made from pewter or stainless steel. 4 What are the underlying causes of the problems at Executive Holloware? One of the main problems is that there is no dimensional / defect inspection carried out until the product is ready for shipment. Too many problems are getting ignored during the manufacturing processes and the product is getting passed down the line with defects. It appears that there is no quality control data generated during the processes until the end of the production line. For this company, the data would not have to be complex, just a numerical count of defects and possible reasons. There definitely seems to be a lack of control chart knowledge. The problems with defects are causing a massive amount of rework, which costs the company money as work is being done twice, this should be virtually unnecessary. The culture of the workforce is wrong. It appears that this stems from the top as the Production Director, Andrew Keegan, is constantly pressuring them to speed up production. This will not work if the quality is not under control. It will only multiply the problem or even increase the percentage of rework. It is a reactive culture with people only reacting to problems with the finished product. There seems to be a blame culture affecting the workforce too. Nobody wants to help with the root causes of the problem; they just want to blame somebody else. This could be because the workforce doesnt feel empowered to do anything about the quality problems. They cant stop production if they notice a problem because they will get blamed for a loss of production time. The workforce may be paid per item they get through their station. This is the case in so many industries of this kind. The problem with that is that the workforce is inclined to rush jobs because they know that if there is rework then they will get paid again. Another problem is that when a defect is found the workforce has no way of knowing if it is out of tolerance or not because there is no specification. There are no limits. 5 How should Executive Holloware measure quality at each stage of the process? Statistical Process Control should be used to take periodic samples from the processes and plot sample points on a control chart. It can then be determined whether the process is within limits. Variability is inherent in production processes and the aim is to lessen the variability to random causes. Three quality characteristics have been highlighted in section 3 which can be measured. A specification needs to be drawn up so that the workforce can decide which defects are failures and which are not. There needs to be a set of tolerances for problems like dimensional inaccuracies. The workforce also needs to be provided with measuring equipment to assist with this. A process control chart can be used as shown in Figure 5‑1. The process would be in control if no sample points lie outside the limits, most points are near the average, and there are an equal number of points above and below the centre line. A histogram can then be created to visually show which problems are most significant. A Pareto analysis could also be done to work out which problem is costing the most. Using control charts at each stage it will be possible to pinpoint at which stage defects are caused. A Fishbone diagram could then be used to show all the causes of a particular quality problem. All these visual aids are useful for meetings to aid effectively communicating the message to everybody present. Another approach to quality control is acceptance sampling. This can also be used on a random basis to measure the % defective. As the products are intended to be top quality and supplied to a top end market, this is not really suitable; especially with the large number of non-conforming products. 6 What steps would you advise Paul Stone to take to improve quality? The basic four steps from the Total Quality Management theory should be used: * Step 1: Collect and organize data * Step 2: Identify problematic components or maintenance processes * Step 3: Analyse data after maintenance process monitoring * Step 4: Action plan [5] The management should ask themselves the 5 Whys each time there is a problem with quality. The 5 Whys is a technique that doesnt involve advanced statistical tools, and in many cases can be completed without a data collection plan. By repeatedly asking the question Why at least five times, you can peel away the layers of symptoms which can lead to the root cause of a problem. [6] Paul should advise management to instil a new culture into the workforce. The workforce should be empowered to report problems and stop production if they feel there is a problem. They should also be involved with problem resolution because it has been proven that if a workforce feels more involved then they are more likely to use their process knowledge to come up with solutions for themselves. This would increase morale and is a basic TQM (Total Quality Management) philosophy. There could be daily meetings for each production unit to go through control chart data. There could then be monthly meetings for the entire staff which will make everyone feel involved and issues can be discussed between departments. Installing a continuous improvement mentality should be the goal. Quality control data as discussed in section 5 should be analysed and used to direct resources for improvement efforts. Specifications need to be created for each product stating tolerances for defects of different types and in different locations on the product. Appropriate metrics need to be identified so that problems can be measured against a standard. There could be cause for a pay restructuring so that workers are paid a fixed rate instead of per item. Bonuses could be introduced based on quality production targets as a different type of incentive. Andrew Keegan should be advised that if the efficiency of the process is increased, then this will bring an increase in productivity. Cycle time should also be increased because there will be fewer problems during processes and rework should be rare. The spare capacity introduced from the lack of rework could then be used to increase production and for new product development. It may be possible to reduce manpower which will lower costs and increase profitability. Increased production means increased turnover. One study by the University of Manchester states that success in applying the quality tools and techniques discussed relies on: * In-depth knowledge of the process * Formal training in problem solving techniques * Appropriateness of tools selected for use * Application of simple models at all levels in the organisation to aid communication and learning [7] If this is true then there needs to be formal training of statistical process control and problem solving techniques generally. There must also be involvement from all levels of the organisation. The Six Sigma theory can be used to help this organisation as well and can be applied to all stages of the problem solving process. The DMAIC (Define, Measure, Analyse, Improve, Control) methodology can be used. Six Sigma seeks to improve the quality of process outputs by identifying and removing the causes of defects and minimizing variability in manufacturing, which is exactly what this company needs to do. As quality assurance manager, Paul should take the lead role in this. The six sigma tools matrix (see Table 6‑1) can present a clear roadmap for the problem solver, especially if the problem solver is a novice (Black Belt or Green Belt). Six Sigma may be an appropriate strategy to base the work on but not in place of TQM because, as Dr Rick L. Edgeman from the University of Idaho said: Six Sigma is a highly structured, information-driven strategy for product, system and enterprise innovation and design. In contrast I would say that TQM seeks to satisfy customer needs continuously by providing what they desire at the lowest possible cost as a result of involving a critical mass of the organizations human resource. [8] Different aspects of both of these methodologies / strategies will be helpful for this company. The steps discussed in this section should have a positive effect on the shops as they will be more confident in the product they are selling, and the end users. Works Cited 1.

In telecommunications this is a connection of peripherals together so that they can exchange information. The first such exchange of information was on May 24, 1844 when Samuel Morse sent the famous message "What hath God wrought" from the US Capitol in Washington D.C. across a 37 mile wire to Baltimore using the telegraph. The telegraph is basically an electromagnet connected to a battery via a switch. When the switch is down the current flows from the battery through the key, down the wire, and into the sounder at the other end of the line. By itself the telegraph could express only two states, on or off. This limitation was eliminated by the fact that it was the duration of the connection that determined the dot and dash from each other being short and long respectively. From these combinations of dots and dashes the Morse code was formed. The code included all the letters of the English alphabet, all the numbers and several punctuation marks. A variation to the telegraph was a receiving module that Morse had invented. The module consisted of a mechanically operated pencil and a roll of paper. When a message was received the pencil would draw the corresponding dashes and dots on the paper to be deciphered later. Many inventors including Alexander Bell and Thomas Edison sought to revolutionize the telegraph. Edison devised a deciphering machine. This machine when receiving Morse code would print letters corresponding to the Morse code on a roll of paper hence eliminating the need for decoding the code. 2.2.

Greener Forms of Generating Electricity

A power station is a facility which is used to generate electric power. iAt the center of nearly all power stations is a generator, a rotating machine that converts mechanical energy into electrical energy by creating relative motion between a magnetic field and a conductor. In Bosnia there is a lot of hydro power plants, the biggest ones are: Grabovica, Jablanica, Salkovac, Visegrad etc. There are three different types of power plants, thermal power plants, hydro power plants and solar power plants. In order to make our lives and the lives of our offspring better, we need to investigate and design new greener ways of converting mass amounts of energy into electricity. Solar power plants use an endless power, which is the sun. Beams from the sun hit mirrors which convert the suns energy into electricity. Approximately, every 7. 2 hours, 3. 6kWh electricity is produced. Solar power is clean and green and it can provide enough energy. However, the downside to this type of power is that it isn't cheap. Building a single mirror of 3. 8 meters by 1. 6 can cost up to $60. 00. These mirrors are state of the art which capture the suns light, and turn it into energy. Thermal power plants are bad for the environment because they contribute to global warming by burning fossil fuels. These power plants are still in use today, because they provide a lot of energy and coal is cheap, so it can be burned in large quantities. Most houses today are supplied either by thermal or hydro. Thermal is very bad for the environment and since the industrial revolution kicked in global temperatures have been rising. Another type of power is wind power. Wind turbines are rotary devices that get provide energy using the air. This type of technology is not to be sniffed at as wind power can sometimes provide more energy than burning coal. There is a downside to this as well. Staying green and using wind powered turbines can cost a lot of money. Staying green and investing in these ideas will matter in the future. By burning excess fossil fuels we are creating green house gasses which are heating up the planet, thus destroying a lot of environments. (2) In Bosnia, the biggest hydro power plant produces around 170. 00 cubic meters of water that reach speeds of 60 km per hour. This is enough water to fill up around 100. 000 Olympic swimming pools every day. Hydroelectric stations have been up and running for about 100 years, and since been scientists have been searching for a way to harvest the energy better. The main idea behind these power stations is to convert the energy of flowing water into the flow of electrons or electricity. Most hydroelectric stations use either water diverted around the natural drop of the river such as a waterfall or rapids. In addition to this a damn is also built across the river to raise the river to create the drop needed to provide a force. Water in the higher level is collected in the reservoir, which flows into the pipe called the pen star which carries it down to a turbine water wheel at the lower water level. The water pressure increases as it flows down the pen star, it is this pressure and flow that drives the turbine which is connected to the generator. Inside the generator is the rotor which is spun by the turbine. Electro magnets are attached to the rotor located within coils of copper wires called a starter. AS the generator rotors spin the magnets, a flow of electrons is created in the coils of the starter. This produces electricity that can be stepped up in voltage through the stations transformers and sent to this transmission lines. The following water the proceeds down the river. Most of our energy comes from the spinning of the rotor of the AC generator in power stations like Nuclear power stations, thermal and hydro power stations. An AC generator is a device which converts mechanical energy into electricity. The working of an AC generator is based on electromagnetic induction which states that whenever the flux passing through a circuit changes, an EMF is induced in it and a current begins to flow. The direction of this is given by Lenz`s law or Flemings right hand rule. Lenz`s law which is more commonly used states that the direction of the induced current is such as to oppose the very cause producing it. (1) In our homes we use open electrical circuits which is very important as with them we do not use direct current.
