Toyota Case free essay sample

catHow Toyota uses 5s 5s in 5 minutes Developed in Japan, this method assume no effective and quality job can be done without clean and safe environment and without behavioral rules. The 5S are five action verbs (Sort, Clean, Set in order, Standardize and Progress), all starting with an S in Japanese (Seiri, Seiton, Seiso, Seiketsu, Shitsuke). The name â€Å"Five S† now identify this method. The 5S allow to set up a well adapted and functional work environment, ruled by simple yet effective rules. S deployment is to be done in a logical and progressive way. The 3 first S are shop floor actions, while the 2 lasts are sustaining and progress actions. Apparently simple, the 5S are a consistent and powerful set. Their correct deployment allows change and progress far beyond just perform cleaning (or order the cleaning to be done). 5S are the solid base, the foundation on which to build continuous improvement, install lean manufacturing tools and methods.

Efficient work and quality require clean environment, safety and discipline. 5S are simple, effective rules for tidiness. Principle of 5S The 5S are prerequisites for any improvement program. The basic assumption states â€Å"wastes are potential gain, eliminating wastes is a gain†. The 5S philosophy is a way of thinking, focusing on effective work place organization, simplified work environment, strives waste reduction while improving quality and safety. There is no chance for efficiency or quality improvement within dirty work place, waste of time and scrap. The five S stand for the five first letters of these Japanese words: Meaning Seiri Sorting Out Seiton Systematic Arrangement Seiso Spic and Span Seiketsu Standardizing Shitsuke Self-discipline It is recommended to start implementing 5S in a well chosen pilot workshop or pilot process, and spread to the others step by step. Lets see how Toyota does PS. I got the pictures from this site excellent blog about TQM.

Facts About the Dwarf Seahorse

Facts About the Dwarf Seahorse The dwarf seahorse  (Hippocampus zosterae)  is a small seahorse  found in the Western Atlantic Ocean. They are also known as little seahorses or pygmy seahorses.   Description: The maximum length of a dwarf seahorse is just under 2 inches. Like many other seahorse species, it has a variety of color forms, which range from tan to green to almost black. Their skin may be mottled, have dark spots, and covered in tiny warts. These seahorses have a short snout, and a coronet on top of their head that is very high and column-like or knob-like in shape. They may also have filaments extending from their head and body.   Dwarf seahorses have 9-10 bony rings around their trunk and 31-32 rings around their tail.   Classification Kingdom: AnimaliaPhylum: ChordataClass: ActinopterygiiOrder: GasterosteiformesFamily: SyngnathidaeGenus: HippocampusSpecies:  Zosterae Habitat and Distribution Dwarf seahorses live in shallow waters populated with  seagrasses. In fact, their distribution coincides with the availability of seagrasses.  They may also be found in floating vegetation. They live in the Western Atlantic Ocean in southern Florida, Bermuda, Bahamas and the Gulf of Mexico. Feeding Dwarf seahorses eat small crustaceans  and tiny fish. Like other seahorses, they are ambush predators, and use  their long snout with a pipette-like motion  to suck in their food as it passes by. Reproduction The breeding season for dwarf seahorses runs from February to November. In captivity, these animals have been reported to mate for life. Dwarf seahorses have a complex, four phase  courtship ritual that involves color changes, performing vibrations while attached to a holdfast. They may also swim around their holdfast. Then the female points her head upward, and the male responds by also pointing his head upward. Then they rise up into the water column and intertwine tails.   Like other seahorses, dwarf seahorses are ovoviviparous, and the female produces eggs that are reared in the males brood pouch.  The female produces about 55 eggs which are about 1.3 mm in size. It takes about 11 days for the eggs to hatch into miniature seahorses which are about 8 mm in size.   Conservation and Human Uses This species is listed as  data deficient  on the  IUCN Red List  due to a lack of published data on population numbers or trends in this species. This species is threatened by habitat degradation, especially because they rely on such shallow habitat.  They also are caught as bycatch  and caught live in Florida waters for the aquarium trade. In the U.S., this species is a candidate for listing for protection under the Endangered Species Act. References and Further Information: Irey, B. 2004. Hippocampus zosterae. Animal Diversity Web.

Mixing Regular and Synthetic Motor Oils

Mixing Regular and Synthetic Motor Oils Heres a practical chemistry question for you: Do you know what happens if you mix regular and synthetic motor oil? Lets say the mechanic put synthetic oil in your car when you got your oil changed. You stop at a gas station and see you are running about a quart low, but all you can get is regular motor oil. Is it alright to use the regular oil or will you risk harming your engine by doing so? Mixing Motor Oil According to Mobil Oil, it should be fine to mix oils. This manufacturer states it would be unlikely anything bad would happen, such as a gel-forming from an interaction of the chemicals (a common fear), because the oils are compatible with each other. Many oils are a blend of natural and synthetic oils. So, if you are low on oil, dont be afraid to add a quart or two of synthetic oil if you are using regular oil or even regular oil if you are using a synthetic. You dont need to rush right out and get an oil change so youll have pure oil. Possible Negative Effects It is not recommended to routinely mix oils because the additives in different products may interact or the oils may become destabilized by the mixture. You may reduce or negate the properties of the additives. You could lose the benefits of the more expensive synthetic oil. So, adding regular oil to your special synthetic oil will mean youll need to get your oil changed sooner than you would have otherwise. If you have a high-performance engine, its possible it will be displeased if the (expensive) additives cant work the way they are supposed to. This may not damage your engine, but it wont help its performance. The Difference Between Regular and Synthetic Oil Both conventional and synthetic motor oils are derived from petroleum, but they can be very different products. Conventional oil is refined from crude oil. It circulates through the engine to keep it cool and prevent wear by acting as a lubricant. It helps prevent corrosion, keeps surfaces clean, and seals the engine. Synthetic oil serves the same purpose, but its tailored for higher temperature and pressure. Synthetic oil is also refined, but then its distilled and purified so that it contains fewer impurities and a smaller, select set of molecules. Synthetic oil also contains additives intended to help keep an engine cleaner and protect it from damage. The main difference between regular and synthetic oil is the temperature at which it undergoes thermal degradation. In a high-performance engine, regular oil is more apt to pick up deposits and form sludge. Cars that run hot do better with synthetic oil. For most automobiles, the only real difference youll see is that synthetic costs more initially but lasts longer between oil changes.

Motivation Assignment Case Study Example | Topics and Well Written Essays - 1500 words

Motivation Assignment - Case Study Example These aspects can determine the level of motivation among employees (The Certified Accountant, â€Å"Expectancy Theory†). There are several disciplines in the field of motivation and one of them is the expectancy theory. This theory is devised by Victor Vroom. He assumed that motivating an employee requires making a connection between effort, performance and inspiration. The productivity of employees depends on aspects like employee behavior, ability, knowledge, experience and proficiency. Vroom’s expectancy theory is made on the basis of three attributes which are Valence, Expectancy and Instrumentality (The Certified Accountant, â€Å"Expectancy Theory†). Valence: It is the emotional direction which employee embraces with respect. The desire of employee can be extrinsic benefits like higher income, job promotion, free leisure time or intrinsic benefits like job satisfaction. Organizations need to determine the acts that can make an employee more grateful. Expectancy: Expectancy deals with the faith of employee about his/her ability. Each employee possesses dissimilar expectations and degree of confidence about their capability. Expectation is illustrated as the strength of an employee’s faith if a particular task is achievable or not. Organization must find out the materials, training and administration requirement of employee for a particular task. Instrumentality: Instrumentality is the idea of gaining something after completing a task. An employee always thinks that if he/she performs well, a worthy result will be gained. Thus, it is the perception of employee that whether he/she will gain the expected result even it is assured by the organization. It is the responsibility of organization to make sure that promised compensations are realized. The following figure shows the relationship between Valence, Expectancy and Instrumentality. The instrumentality is impacted by the belief among

NAEYC article assignment Essay Example | Topics and Well Written Essays - 250 words

NAEYC article assignment - Essay Example The United States is a diverse country and an early education centre is likely to have many children with different linguistic backgrounds. The inability of early child educators to speak all the home languages of children makes it difficult to preserve those languages. The lack of programs focusing on instilling early educators with relevant languages makes it impossible for the teachers to respond appropriately to the call of preserving home languages of children. The design of early education program still makes it a huge challenge for early educators to meet the needs of children and families in terms of linguistic and cultural diversity. Early childhood programs are basically designed with the main language as English, which does not reflect the diverse nature of the American population. The implementation of the NAEYC recommendations requires complete dedication of the early childhood educator. As such I will actively engage with parents and strive to gain knowledge about all the children in order to ensure that each child is served better. I will ensure coherent working relationship with parents in order to ensure that I provide quality care and education for every child under my

Montaigne, Studentessa, and Performance :: Music Composition Studies

Montaigne, Studentessa, and Performance The field of composition studies has worked to define and make sense of the "basic writer" for decades. In 1977, Mina Shaughnessy called basic writing the "pedagogical west," a frontier, "unmapped, except for a few blazed trails that individual teacher propose through their texts" (4). Since Shaughnessy, the work of David Bartholomae, Min Zhan Lu, Bruce Horner, and others, has expanded upon, and called into question, the term "basic writer." In this paper, rather than do away with the term altogether, I will offer a study of a writer who would be typically labelled "basic." This study will place her work beside that of an acclaimed and historical "expert," Michel de Montaigne. Through a series of close readings, I hope to illustrate the rhetorical oves from dialogue to performance that "Studentessa" (a former and anonymous student of mine) undergoes in her writing. At the same time, I will mark moments in which Montaigne reinscribes these rhetorical moves into his own writing. U ltimately, these points of intersection will reveal the richness inherent in study of writers we call "basic," and allow greater appreciation for the performative abilities of Montaigne. The scope of Studentessa's audience, particularly with her first attempts at essay-writing, is extremely intimate. Specifically, Studentessa is talking to me, the instructor, in an attempt to answer my questions in writing. The first essay that we read in class was Richard Rodriguez's "Achievement of Desire," a biographical account of Rodriguez's education and emotional growth. For their own writing assignment, students were asked to come up with a definition of education, and to test this definition against their understanding of Rodriguez. Studentessa did put together an initial thesis about education: "Education is an essential aspect of our lives. Education is something that you share, but you as an individual can learn it for yourself." During one of our many discussions, I asked Studentessa what pieces made up "education"--were there different forms of education? In response, Studentessa came up with forms: first, of course, was "school," second, was "life experience" (whi ch broke down into "mother wit" and "street smarts"), and third, "relationships." We talked about the importance of applying these forms to Rodriguez's experience: Did his education involve street smarts? In a revised draft, after our weekly meeting, Studentessa writes, "there is another form of education called street-smarts, these people can survive on the streets with their wit.

Donner Case

Order Size for drilling: * The Manual press needs 15 min for set up, in addition to 0. 08 min for every hole. Knowing that the typical circuit board has 500 drilled holes, then run time will be 0. 08*500 = 40 min / board. Therefore, time taken to drill N boards manually will be equal to : 15 + 40(N) * On the other hand the CNC drill needs 240 min for set up, in addition to 0. 004 min for every hole. So run time will be 0. 004*500 = 2 min / board.Then the time taken to drill N boards by CNC drill will be equivalent to : 240 + 2(N) * It is then logic to conclude that we will use CNC drill only in order sizes that will provide timing benefit over manual press. i. e. when 240 + 2N < 15 + 40N which means N 6 * However the shop floor policy dictates that only orders for more than 100 boards be drilled by CNC drill !!!!! Surely this must be changed * This means that they used the CNC drill in only 12 orders of the 60 orders received in September, while actually they should have used it in 3 5 orders ( all orders 6) !!Order Size for Profiling: * Set up time for Punch press is 50 min, while run time is 1 min / board. So Time taken to profile N orders will be 50 + N * While set up time for CNC routers reaches 150 min, in addition to 0. 5 min / board run time. So the time needed to complete profiling of N boards equals 150 + 0. 5(N) * Thus CNC reuters will produce time benefit if used only in orders more than 200 boards Capacity of Dry Film Photo Resist area: * Assuming order size equals 8 boards Then the panel preparation will take 5 + 0. = 5. 2 min Lamination & Exposure will take 20 + 2 = 22 min Development will take 20 + 0. 2 = 20. 2 min * This means that Lamination and exposure are the bottle neck of the process, and the cycle time for this step will be 22 min / panel. Which means that the capacity will be 2. 7 panels / hour * If we increased order size to 2 panels (16 boards) Panel preparation will take 5 + 0. 4 = 5. 4 min Lamination & Exposure will take 20 + 4 = 24 m in Development will take 20 + 0. 4 = 20. 4 min Lamination & exposure are still the bottle neck of the process, but the cycle time drops to 12 min / panel raising the capacity to 5 panels / hour..
