Study of Tools, Techniques and Factors used in Lean Six Sigma
Lean Enterprise originated from the Toyota Motor Corporation as the Toyota Production System, and increased in popularity after the energy crisis. The concept of Six Sigma was develop in the early 's at Motorola Corporation. General Electric Corporation popularized six Sigma in the late 's. Lean Six Sigma is an approach focused on improving quality, reducing variation and eliminating waste in an organization.
The concept of combining the principles and tools of Lean Enterprise and Six Sigma has occurred in the literature over the last several years. The majority of Lean Six Sigma applications have been in service private industry, focusing mostly on manufacturing applications . Lean manufacturing:Lean manufacturing is a manufacturing philosophy, which focuses on delivering high quality products at the lowest price and at the right time.
Lean manufacturing focuses on eliminating waste or non-value added activities, leans basic value proposition is that principles for improving workflow, decreasing setup time, eliminating waste, and conducting preventive maintenance will speed up business processes and return quick financial gains . Table 1 below shows the types of wastes of Toyota production system. Six sigma:Six Sigma is "a program aimed at the near-elimination of defects for every product, process and transaction.
Improvement projects are driven in a wide range of areas and a different level of complexity, in order to reduce variation. The main purpose of reducing variation on a production or service is to satisfy customers. The goal of six sigma is that only 3. Six sigma has two methods: Continuous improvement DMAIC methods:The methodology used to improve an existing process in six sigma is the DMAIC process, which is divided into five stages: Define: the purpose of this phase is to clarify the goals and value of a project.
Measure: the purpose of this phase is to gather data on the problem. Analyze: the purpose of this phase is to examine the data and process maps to characterize the nature and extent of the defect. Improve: the purpose of this phase is to eliminate defects in both quality and process velocity. Control: the purpose of this phase is to lock in the benefits achieved by doing the previous phases.
Verify: the purpose of this phase is to verify the design performance and ability to meet customer needs. Illustrates the tools and techniques used in lean manufacturing, six sigma and the common tools and techniques between them. Lean Six Sigma:Lean Six Sigma is an approach focused on improving quality, reducing variation and eliminating waste in an organization.
It is based on the concepts of combining two improvement programs, Six Sigma and Lean manufacturing, also known as Lean Enterprise. Six Sigma is both a quality management philosophy and a methodology that focuses on reducing variation, measuring defects and improving the quality of products, processes, and services , , .
The study aims to: 1 clarify the concept of lean, six sigma and lean six sigma in practice and how to execute and perceive lean six sigma. The literature search is limited to the English language only and available from to October lean Manufacturing [6,7,, Six Sigma [15,, Lean Six Sigma [1,3,16,18,.
The criteria of selection of the papers includes the publication years, either applied as a case study or described as theory and the field of implementation. The search results were sort out as case study or theories, classify by sectors, factor focused, tools and techniques used and have been focused to important sectors industry, service and health. The data collected are analyzed and the results are present in graphs. Figure 4 illustrates the cumulative sectors, which used in Lean Six Sigma, according to year.
From this figure, it can be shown that the industry sector is the most used the lean six sigma, follow general sector, health and service but the less cumulative used IT, environmental and finance sectors. Figure 5 shows the lean six sigma implemented in the industry sector where the defects are less tolerable. Followed by general sector includes printing, military, education, government, decision making and recycle materials.
Followed by service sector includes mainly banks, investment, call centers, telecommunication and computer technology. Followed by health care sector where the defects not allowed, health sector includes pharmaceutical, clinical and drugs. It illustrates the incremental to Figure 3. Figure 7. Figure 8. Shows the cumulative tools and techniques of Lean Six Sigma, according to year; from this figure, it is clear that the tools and techniques was use most in year Figure 9. Shows the tools and techniques most commonly used in lean Six Sigma in the health sector; from this figure, it is clear that the cause and effect diagram was the most widely technique used in this sector, but value stream mapping technique was the least technique used in this sector.

Lean Manufacturing Tools Techniques and How to Use Them
Melnyk R. Chris Christensen. Ptak with Eli Schragenheim. Includes bibliographical references p. ISBN X alk.
The term "Lean" was coined in by John Krafcik , and defined in by James Womack and Daniel Jones to consist of five key principles: 'Precisely specify value by specific product, identify the value stream for each product, make value flow without interruptions, let customer pull value from the producer, and pursue perfection. Insights relating to value streams , efficiency reduction of "waste" , continuous improvement and standardised products can most likely be traced back to the beginning of humankind. However, Fredrick Taylor and Henry Ford documented their observations relating to these topics, and Shigeo Shingo and Taiichi Ohno applied their enhanced thoughts on the subject at Toyota in the s. American industrialists recognized the threat of cheap offshore labor to American workers during the s, and explicitly stated the goal of what is now called lean manufacturing as a countermeasure. Henry Towne, past President of the American Society of Mechanical Engineers , wrote in the Foreword to Frederick Winslow Taylor's Shop Management , "We are justly proud of the high wage rates which prevail throughout our country, and jealous of any interference with them by the products of the cheaper labor of other countries. To maintain this condition, to strengthen our control of home markets, and, above all, to broaden our opportunities in foreign markets where we must compete with the products of other industrial nations, we should welcome and encourage every influence tending to increase the efficiency of our productive processes. Continuous production improvement and incentives for such were documented in Taylor's Principles of Scientific Management :.
hesitant to adopt lean manufacturing tools and techniques to the continuous process industry because of reasons such as high volume and low.

The Six Sigma expert uses qualitative and quantitative techniques to drive process improvement. Although the tools themselves are not unique, the way they are applied and integrated as part of a system is. Some of the statistical and graphical tools commonly used in improvement projects are:. It is an integral part of a Six Sigma initiative, but can also be implemented as a standalone quality improvement procedure or as part of other process improvement initiatives such as lean. It's designed to help build a quality work environment, both physically and mentally.

Lean management is one of the top tools that eliminate waste in any process. Lean techniques are typically used in a production environment, and most examples in Lean training courses will focus on applying Lean techniques in these kinds of processes. The reality is that Lean techniques can be used in any environment that uses processes. Because Lean and the Six Sigma method goes hand in hand.
Lean tools got their start in America as early as the s, when Henry Ford used Lean methodology to create the Model T assembly line. Lean methodology also has an expansive legacy outside the U. In addition to being the first to correctly implement the Lean tool Just-In-Time, for example, Toyota is also known for creating its own Lean Production System. Lean tools are utilized across many industries—from manufacturing to engineering to finance— and organizations often leverage them together with Six Sigma methods. Though there are some differences between the two frameworks, the underlying philosophies behind Lean and Six Sigma complement each other exceptionally well: Lean tools are designed to eliminate invaluable processes, while Six Sigma focuses on lessening variation within a process.

Танкадо отдал кольцо? - скептически отозвалась Сьюзан. - Да. Такое впечатление, что он его буквально всучил - канадцу показалось, будто бы он просил, чтобы кольцо взяли. Похоже, этот канадец рассмотрел его довольно внимательно. - Стратмор остановился и повернулся к Сьюзан. - Он сказал, что на кольце были выгравированы какие-то буквы. - Буквы.
Наполнив тяжелый хрустальный стакан водой из фонтанчика, Беккер сделал несколько жадных глотков, потянулся и расправил плечи, стараясь сбросить алкогольное оцепенение, после чего поставил стакан на столик и направился к выходу. Когда он проходил мимо лифта, дверцы открылись. В кабине стоял какой-то мужчина. Беккер успел заметить лишь очки в железной оправе. Мужчина поднес к носу платок.
И вот эти два интеллектуала, казалось бы, неспособные на вспышки иррациональной влюбленности, обсуждая проблемы лингвистической морфологии и числовые генераторы, внезапно почувствовали себя подростками, и все вокруг окрасилось в радужные тона. Сьюзан ни слова не сказала об истинной причине своей беседы с Дэвидом Беккером - о том, что она собиралась предложить ему место в Отделе азиатской криптографии. Судя по той увлеченности, с которой молодой профессор говорил о преподавательской работе, из университета он не уйдет.
