Introduction

"Lean" production theory was first used in Japanese factories. The Toyota production system is especially admired as a highly successful use of "lean" techniques. In general, lean production refers to manufacturing processes that improve upon mass production techniques to reduce cost, reduce time to produce, improve quality, and better respond to market demands. The benefits of lean production techniques have been documented in several studies, including a worldwide study of automotive industry. This report will focus on some elements of lean production; give some general description of each element of lean production.

Small-lot Production

Generally, lot-sizing direct affect a company's manufacturing competitive advantage; the reason is this influences the cost, quality, lead time, and flexibility of production. According to different situation for each company, company will design different kinds of lots. For example, when it is the quantity of materials purchased from a supplier it is called a purchase or order quality. Also, there have some other lots, such as process batch, transfer batch and delivery quantity. Small-lot production influence production costs directly. If a company uses large lot, which result in large setup expenses in EOQ-based model, this can give the economic optimum, but this may have disadvantage. When they minimize dollar costs, they lead to greater non dollar costs associated with increased production lead time, hidden defects, and also reduced scheduling flexibility. Cost is not an only factor when company consider, company also should consider demand, production capacity and setup times. When the companies reduce lot sizes, as the result, the number of lots will be incre...

  • Analysis Of Lean In: What You Do If You Weren T Afraid

    386 Words  | 1 Pages

    In Sheryl Sandberg’s essay “Lean In: What You Do If You Weren’t Afraid?”, she talks about how women are afraid to strive for leadership that men pursue for. She mentions how women are afraid to be leaders even though they outperform men academically in their degrees. Women are discouraged to enroll in leadership in the workforce because “they are less valued in the workplace” and “overwhelmingly stocked with men”(Sandberg 646). More importantly, Sandberg points out that the reason women don’t seek for high positioned jobs is that they aren’t “ambitious” as much as men. Not being ambitious allows women to not show themselves that they don’t have a strong desire to obtain the highest leadership. Women aren’t as ambitious than men because they

  • Essay On Continuous Improvement

    1105 Words  | 3 Pages

    Continuous improvement (CI) refers to a philosophy consisting of improvement activities that increase successes and reduce failures in a production process (Bhuiyan & Baghel 2005, p. 761). It involves activities and processes that focus on continuous and incremental innovation (Bessant et al., 1994, p.17). CI is a new approach that enhances productivity, performance, and achieves competitive advantage needed in the highly competitive industries. It may also serve as a complementary approach to other quality improvement initiatives such as total quality management (TQM) (Pike, Barnes, & Barnes 1995, p. 23; Larson 2003; Lassen, Gertsen, & Riis 2006; Oakland 2007, p. 227). The purpose of this research is to explore the application of production systems engineering methods in the CI at manufacturing plants.

  • The Effect Of Lean Six Sigma On The Employee And The Organization

    1957 Words  | 4 Pages

    The methodology of Lean Six Sigma is the merger of two business tools that includes Lean Manufacturing and Six Sigma. Six Sigma focuses on improving current business processes and performance while Lean Manufacturing focuses on the improvement of the processes of an organization by using highly skilled employees to increase speed and quality. Combining the two methodologies creates an organization that focuses on quality, efficiency and speed to lower operational costs and increase profits. By following the Lean Six Sigma methodology, many companies have attempted to create a lean, waste-free environment ultimately at the expense of the employee and occasionally at the expense of the organization.

    Quality is an important part of any business rather from a customer’s perspective or a producer’s perspective. Quality from a customer’s perspective is they “want value and quality has become a major factor in the value of products and service” (Russell & Taylor, 2013, pg. 53). “The customer is the most important part of the production line” (Russell & Taylor, 2013, pg. 53). This can be referred to as quality of design meaning “involves designing quality characteristics into a product or service” (Russell & Taylor, 2013, pg. 54). Now let’s look at the quality from a producer’s perspective. This can be referred to a quality of conformance meaning “making sure the product or service is produced according to design” (Russell & Taylor, 2013,

  • Business Model of Toyota

    According to Toyota, they have undertaken a manufacturing revolution that has fundamentally changed established practices; all the way back to the product development and design. They have done this by integrating four areas: design, production engineering, procurement, and component supply. They have achieved higher quality at lower costs by creating standardized, multipurpose components. Also the reduction in cost has heightened the value and fortifies the competitiveness of product. To do this, Toyota has required intensive coordination with its suppliers. Another factor of their Integrated Low Cost is that Toyota steadily feeds cost improvements back into the product to raise their value along with the fact that four Toyota’s seven corporate auditors are outside corporate auditors.

    Toyota’s core competencies seem simplistic, yet they are very powerful. There are two in which they focus on which is continuous improvement and respect for people. These core competencies are a part of their production system, better known as the Toyota Production System (TPS). The TPS is based on the philosophy “completely eliminating all waste”. Excess inventory, defective products, and unnecessary processing steps are all inclusive when discussing excessive waste, which eventually negatively effects the corporation as a whole. In 1924, Sakichi Toyoda created the Toyoda Automatic Loom, which improved productivity and work efficiency by eliminating wasteful practices and defective products. Kiichiro Toyoda believed that “the ideal conditions for creating things are more successful when machines, facilities, and people work together to add value without generating any waste.” (The orgin of the toyota production system,

  • Production Planning Strategy

    669 Words  | 2 Pages

    All activities in our daily life occur according to a certain plan. Production planning involves making prior decisions on how to carry out a certain strategy in a business which involves: the material to produce, the period of production, and the exact location to carry out the production process. A well designed plan with good understanding of the future outcomes helps to avoid failure due to uncertainties. Production planning aims at looking ahead and estimating the type of resources required in an organization and then coming up with the proper arrangements which enables attainment of the set production targets in the proposed plan (MBA Knowledge Base, 2011). Production planning strategy therefore involves coming up with ways and means of achieving the above objectives. To implement the plan, the organizing group has to be equipped with the information on the complete data of the product which includes; the expected operations, market research, and the methodology to be put in place.

    ...hould be noted that the process of Lean management was first applied in the area of manufacturing. Some analysts tell that his particular business management process came out of the Toyota Company’s production system of cars. It should be noted that the Japanese are very much inclined to adopt anything that would reduce costs and eliminate wastes. Hence, it is no wonder that the Japanese are known for their simplicity and design and the minimalist view on things. However, nowadays has evolved from the area of manufacturing and could now be applied in the area of management. Before moving forward to the essential principles of Lean management, it would be better to clearly define it first. The said book by Bradley did not really give a definite and concise definition of Lean. Instead, he tried to define this said business management concept though examples.

  • Toyota's Competitive Strategy Of Toyota

    1622 Words  | 4 Pages

    Its objective is to integrate people, process, and technology. Toytoa’s product development procedure is essentially different from a manufacturing process. Its backbone is not visible, but knowledge and information which are untouchable. The product development’s cycle time is much longer than hours. It usually takes weeks or even months. The production chains are non-linear and multi-directional. Workers are no longer manufacturing workers but specialists with high diverse technology. This product development strategy is viable for Toyota. This is because this strategy does help Toyota to prolong the life cycle of current product. For instance, Toyota Camry is a very successful current product which is prolonged its life. Camry has been made since 1980s. Camry is set at an middle-high level of family veichle. After 30 years development, Camry is still very famous all over the world. This cannot be separeted by Toyota’s successful product development strategy. One of the key features of the Toyota product development system is functional engineering managers. They are primarily teachers in the Toyota system, who are the most technically competent engineers, with the highest levels of experience. Toyota’s management group is consist of high educated experts. They were all engineers and their technical excellence is very famous. But recently, Toyota’s product development system does not work very well. In
