...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 Production Manufacturers and companies are seeking methods in order to provide customers with the best quality of products and services in all over the world. These entities try to eliminate or reduce their products wastes, inefficiency, and anything that might affect their products or customer service. Lean manufacturing has been created as a consequence of the Toyota Production System (TPS) and it was called “Lean” in the 1990s. Based on the article called, “Lean manufacturing”, the following facts have been stated: Lean manufacturing or lean production, often simply, "Lean," is a production practice that considers the expenditure of resources for any goal other than the creation of value for the end customer to be wasteful, and thus a target for elimination. Working from the perspective of the customer who consumes a product or service, "value" is defined as any action or process that a customer would be willing to pay for. Lean operation is a costly process, but the manufacturers see that its profit is worth to pay a lot of money in order to change their systems into this system. Some of its benefits are: Minimizing inventory and cost, increasing profit, and maximizing efficiency. In order to change to this lean production, manufacturers need to do some additional jobs, so that their employees and products can meet the minimum requirements for a lean operation. Quality is much more important than quantity in this system. Businesses prefer to produce less amount with...

...Lean Management In Automobile Industry Lean Management In Automobile Industry Arvinder Singh, Bargavi Poloju, Inderpreet Kaur, Inderjeet Kaur, Jaskaran Singh Gill Eastern Institute of Technology September 10, 2015 Abstract Lean and six sigma are widely known business improvement processes for industries /organisations these days for achieving drastic results, which are majorly cost cutting, quality maintenance and time management by specializing in processes to boost performance. Nowadays, There are some industries that are even integrating lean and six sigma into a more cohesive strategy i.e., lean sigma in order to establish even more powerful and effective process which focuses at eliminating wasteful activities and retaining most of the strengths of each activity. Lean Sigma aims to combine waste eliminating strategies of Lean Thinking with variability reducing techniques of six sigma to promote growth and increase revenue from the bottom line of organisations(M. Kumara). Lean management is outlined as a consistent and a methodical approach to determining and eliminating waste through continuous improvement, flowing the merchandise at the pull of the client in pursuit of perfection. The idea of lean management was developed for maximizing the resource utilization through reduction of waste, and eventually lean was developed in response to the unsteady and ever-competitive business organisations. For organisations to face major challenges and competition can be...

...JIT Just in time (JIT) is a production strategy that strives to improve a business return on investment by reducing in-process inventory and associated carrying costs. Just-in-time production method is also called the Toyota Production System. To meet JIT objectives, the process relies on signals or Kanban (看板 Kanban?) between different points in the process, which tell production when to make the next part. Kanban are usually 'tickets' but can be simple visual signals, such as the presence or absence of a part on a shelf. Implemented correctly, JIT focuses on continuous improvement and can improve a manufacturing organization's return on investment, quality, and efficiency. To achieve continuous improvement key areas of focus could be flow, employee involvement and quality. Quick notice that stock depletion requires personnel to order new stock is critical to the inventory reduction at the center of JIT. This saves warehouse space and costs. However, the complete mechanism for making this work is often misunderstood. For instance, its effective application cannot be independent of other key components of a lean manufacturing system or it can "...end up with the opposite of the desired result." In recent years manufacturers have continued to try to hone forecasting methods such as applying a trailing 13 week average as a better predictor for JIT planning; however, some research demonstrates that basing JIT on the presumption of stability is inherently flawed. ------------------------------------------------- ...

...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...

...Opportunity Cost and the logic of lean Production at Boeing Pg. 44 Ch.2 In the summer and fall of 2010, workers were rearranging the furniture in Boeing’s final assembly plant in Everett, Washington, in preparation for the production of the Boeing 767. It was a difficult and time-consuming process, however, because the items of “furniture”—Boeing’s assembly equipment—weighed on the order of 200 tons each. It was a necessary part of setting up a production system based on “lean manufacturing,” also called “just-in-time” production. Lean manufacturing, pioneered by Toyota Motors of Japan, is based on the practice of having parts arrive on the factory floor just as they are needed for production. This reduces the amount of parts Boeing holds in inventory as well as the amount of the factory floor needed for production—in this case, reducing the square footage required for manufacture of the 767 by 40%. Boeing had adopted lean manufacturing in 1999 in the manufacture of the 737, the most popular commercial airplane. By 2005, after constant refinement, Boeing had achieved a 50% reduction in the time it takes to produce a plane and a nearly 60% reduction in parts inventory. An important feature is a continuously moving assembly line, moving products from one assembly team to the next at a steady pace and eliminating the need for workers to wander across the factory floor from task to task or in search of tools and parts. Toyota’s lean production techniques have been...

...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...

...The strategic initiatives from our list include the following: 1. Efficient Consumer Response (ECR): Lean Manufacturing Japan (2008) stated that ECR “is a strategy to increase the level of services to consumers through the close cooperation among retailers, wholesalers and manufacturers. Lean Manufacturing Japan (2008), also stated that “ECR reduces the opportunity loss, inventory level, and entire cost, increases monetary profitability by sharing the purpose of customer satisfaction. 2. Just – in – Time (JIT): simply means getting the right quantity of goods at the right place and right time and it originated from Japan after World War II by Toyota Motor Company (Reid & Sanders, 2007). There are three elements of JIT which are: Just in time manufacturing, Total Quality Management and Respect for people. 3. Lean System: Also known as Just – in – Time. Lean simply means the elimination of waste, with perfect quantity to meet demand instantaneously. Lean has four elements which are: Customer focus, synchronized flow, behavior and waste elimination (Slack &Lewis, 2011). Lean operations help to reduce cost, gives higher quality, reduce lead time, increase productivity and reduce amounts of waste (Wikispaces, n.d) 4. Agile Operations: is the ability to react and adapt to the changes in demand and supply situations in a supply chain (Sehgal, V., 2010). 5. World Class Manufacturing (WCM): It is the best practices which can be use to describe best manufacturers (Hosseinie et al. 2012)...
