INTRODUCTION
Manufacturing has been recognized as the main engine for growth of the economy. Ever changing globalized environment has been posing challenges of competitiveness and survival to all the constituents of the economy. Manufacturers industry have always faced heightened challenges such as rising customer’s demand for better and improved products, erratic demand, and competition in markets. There is no disbelief that the manufacturers are always embracing changes and improvements in their key activities or processes to cope with the ever growing challenges.
To be more efficient is the only way to stay and earn profit in a global market. Industries are giving lot of attention to Lean manufacturing. Several industries are struggling to be world class. Principal adoption of lean manufacturing is still found to be complex. Lean Manufacturing is a set of techniques, which have developed gradually over a long period and are based on various minor to major breakthroughs that help in reducing cost and hence increase productivity.
Lean is a philosophy of manufacturing that incorporates a collection of principles, tools and techniques into the business processes to optimize time, productivity, HR, and assets, while improving the quality level of products and services to their customers.

LEAN MANUFACTURING
Lean manufacturing is defined as to produce same and more than the mass production using less effort, lesser space, without any new inventory, better quality and lesser defects.
Lean manufacturing improves operating performance by focusing on the quick and uninterrupted flow of products and materials through the value stream. To achieve this, the various forms of manufacturing waste must be identified and eliminated. Waste can include any activity, step or process that does not add value for the customer.
If we try to define Lean Then we can say “A systematic

About a Boy

...Jenny Smith November 28, 2011 Dr. Min Young Lee English 121 sec 28 The Coming of Age of the Male Characters in About a Boy About a boy is a contemporary novel written by the British author Nick Hornby. It incorporates constructs of post-modern writing by bringing into focus the artists, and styles, and prose of the vernacular. The setting of the novel takes place in London in the mid 1990s. About a boy gives a unique perspective of a coming of age story. It follows the coming of age of two boys of two very different ages; Will Freeman 36 years old and Marcus 12. This novel shows the contrast between consumerism and materialism with real interpersonal connections. Will Freeman made the decision to pursue materialism rather than personal friendships, and to live in self-imposed isolation. Will had the ability to buy “cool” clothes, and sunglasses and sneakers, and so was never at a loss for acquaintances. Marcus, on the other hand, felt isolation due to a lack of materialism. Marcus was an outsider in his school in London since he could not have the best “coolest” clothes, shoes, and haircuts and thus was always the target of bullying. However, as the plot progresses, Marcus and Will undergo transformational experiences together to become more connected to the people around them. The transformational experiences of Fiona’s suicide, falling in love, and Marcus’ arrest all culminate in the maturation of Will and Marcus’ and the genesis of interpersonal connections between...

Lean Accounting

...The Principles, Benefits and Compliance of Lean Accounting As a way to reduce costs, manufacturing businesses today are looking for a leaner approach to production and are focusing on the overall process of producing an item to eventually sell to a consumer. This process is called the value stream, which is defined in Cost Accounting: A Managerial Emphasis as “the value-added activities needed to design, manufacture, and deliver a given product or product line to customers” (Horngren, Datar, & Rajan, 2014, p. 635). With the assistance of technology advancements to support with the communication of the different components of the value stream, processes have been developed, like Just in Time (JIT) production, that allow for the lean production of merchandise. Dan Woods describes this lean production process, in an article published in Forbes: “In a lean process, the demand signals pull the materials through the flow processes and the right number of products is created with as little waste as possible. When all the suppliers of materials are also making their processes lean, the result is that the entire supply chain is extremely responsive and efficient. “ (Wood, 2009) To go along with this lean production system, lean accounting was developed as “a costing method that focuses on value streams, as distinguished from individual products or departments, thereby eliminating waste in the accounting process” (Horngren, Datar, & Rajan, 2014, p. 635).

Some hospitals have used Lean to help eliminate point-of-care testing for the emergency department (ED). Other hospitals have used Lean to “insource” testing that had previously been done in outside reference laboratories. Lean can defend and protect employment for the laboratory, while also improving turnaround times and service for patients and reducing costs for the hospital. Hospital laboratories have also used freed up capacity to increase their reference laboratory work, bringing additional revenue to the hospital. an improvement of 37%, as shown in Figure 1. The laboratory was also better satisfying physicians who ordered tests for morning rounds, as the percent of tests on the charts by 7 am improved from 65% to more than 90%, as shown in Figure 2. After laboratory professionals demonstrated that they could dramatically reduce turnaround times, the ED discontinued the point-of-care trials. Since Lean implementation, Dr. Decker said, turnaround times “are definitely faster. All the docs agree,” adding, “the lab is no longer the rate-limiting step in the process.” Lean Instead of...

Lean Production

...The term ‘lean production’ came about to describe the Toyota production system in the late 1980’s. This came to pass through a research group from MIT who over five years analysed the automotive industry in fourteen countries. It was called ‘lean manufacturing’ rather than the Toyota production system to make it easier for competitors and organizations to adopt this type of system. The concept of lean production in a manufacturing organization basically means to try and maximise the use of materials to achieve optimum customer value and at the same time reducing waste and ensuring the same standard of quality in the finished product. Reducing the resources means it will cheaper for the organization to create the product plus also for the customer to buy it. With regards to a manufacturing organization ‘lean production’ is basically a list of rules, tools and techniques which improves the organization in questions manufacturing processes. The main concept of ‘lean’ in a manufacturing organization is to reduce waste which can be broken down and understood as the seven wastes:- 1. Over-production – One of the worse types of waste which is the manufacture of the product before it is actually needed. This can create excess inventory. 2. Waiting – Time between the manufacturing processes 3. Motion – Time wasted from moving people around 4. Transport – Time wasted from the movement of materials from each manufacturing stage. 5. Inventory – Having too much stock...

Lean Production

...period, Japanese companies developed the concept of lean production. Lean production was regarded as the third step in the historical progression, which took industry from the age of the craftsman through the methods of mass production and into an era that combined the best of both (The Economist 2009). Lean production was designed to combine the flexibility and quality of craftsmanship with the low costs of mass production. And due to its unique characteristics bringing an underdog company in its industry to the market leader, this idea of lean thinking has been adopted by many other industries. Today ‘lean’ may no longer be fashionable but its core principles (flow, value, pull, minimizing waste etc.) have become the paradigm for many manufacturing (and service) operations (Lewis 2000). In this essay, my main argument is that although success of lean production and its positive impacts on corporate competitiveness is undeniable, nevertheless, from the workers’ point of view, lean production has also increased the pressures of work and the degree of exploitation wherever it exists. In the first part of my essay I will present a brief history of lean production. This will be followed by the demonstration of main characteristics and the analysis of how lean production has impacted corporate competitiveness by utilizing Toyota as an example, which is the birthplace of lean production. Part three will spell out the limits of lean production as it dramatically increases the pressures...

Lean Manufacturing

...LEAN MANUFACTURING Lean manufacturing is a management philosophy focusing on reduction of the seven wastes to improve overall customer value: • Over-production • Transportation • Inventory • Motion • Waiting time • Processing Itself • Defective Product (Scrap in manufactured products or any type of business.) By eliminating waste (muda), quality is improved, production time and costs are reduced. To solve the problem of waste, Lean Manufacturing has several "tools" at its disposal. These include constant process analysis (kaizen), "pull" production (by means of kanban) and mistake- proofing (poka-yoke). Key lean manufacturing principles include: • Pull processing: products are pulled from the consumer end (demand), not pushed from the production end (Supply) • Perfect first-time quality - quest for zero defects, revealing & solving problems at the source • Waste minimization – eliminating all activities that do not add value & safety nets, maximize use of scarce resources (capital, people and land) • Continuous improvement – reducing costs, improving quality, increasing productivity and information sharing • Flexibility – producing different mixes or greater diversity of products quickly, without sacrificing efficiency at lower volumes of production • Building and maintaining a long term relationship with suppliers through collaborative risk sharing, cost sharing and information sharing arrangements.

Lss Lean

...LSS lean Six Sigma Abstract Purpose – Although research has been undertaken on the implementation of lean within various industries, the many tools and techniques that form the “tool box”, and its integration with Six Sigma (mainly through case studies and action research), there has been little written on the journey towards the integration of the two approaches. This paper aims to examine the integration of lean principles with Six Sigma methodology as a coherent approach to continuous improvement, and provides a conceptual model for their successful integration. Design/methodology/approach – Desk research and a literature review of each separate approach is provided, followed by a view of the literature of the integrated approach. Findings – No standard framework for lean Six Sigma or its implementation exists. A systematic approach needs to be adopted, which optimises systems as a whole, focusing the right strategies in the correct places. Originality/value – This paper contributes to knowledge by providing an insight into the evolution of the lean Six Sigma paradigm. It is suggested that a clear integration of the two approaches must be achieved, with sufficient scientific underpinning. Keywords Lean production, Six sigma Paper type Literature review 1. Introduction The Toyota Production System (TPS) provided the basis for what is now known as lean thinking, as popularised by Womack and Jones (1996). The development of this approach to manufacturing began shortly after...

Toshiba Production Case

...tool that represents a different stage in the value stream process. In order to create a lean process, one needs to have a full understanding of the business, production processes, material flows and information flows. Understanding the proper flow of the product maximizes value throughout the value mapping stream and will eliminate waste without making major cost error. Value stream mapping is not limited to manufacturing processes but, can be applied to service, logistics, distribution, or virtually any type of process. The Current State We can start by taking a look at the current state of this process starting with the supplier and ending with the customer. ******************************************************************** Discussion Questions 1.   Is it possible to achieve zero inventories? Why or why not? In reality, zero inventories are a challenging, if not impossible, goal for most organizations. The concept is theoretical because the ideal production unit is one. Nothing is made until the customer expresses an unmet need for the product. In reality, inventories will always exist due to the timing between the expressed need and the actual delivery of the completed unit(s). Nevertheless, this goal aids in understanding of the lean concepts, and remains a reference point to continually remember in the on-going improvement process.  2.   One way to help achieve lean production systems is to employ flexible automated manufacturing equipment and automated...
