Advantages And Disadvantages Of Six Sigma

Lean Six Sigma concepts were introduced in the book titled Leaning into Six Sigma: The Path to Integration of Lean Enterprise and Six Sigma (Lean Six Sigma). Lean Six Sigma methodologies combine lean manufacturing and Six Sigma strategies to rely on improved performance from a collective team effort that systematically reduces variation and removes seven kinds of waste, known as Muda. Muda includes any unnecessary motion, transport, wait time, inappropriate processing, excess inventory, overproduction, and defects (Lean Six Sigma). Furthermore, Lean Six Sigma methods aim to provide customers with the best possible quality, cost, and delivery (ASQ.org, n.d.). In all, Lean Six Sigma is a business performance improvement strategy that uses a systematic approach to improving the way people advance processes. Its methodologies allow for systematically enriched processes to satisfy the customer and make money. Simply put, Lean Six Sigma as a business enhancer, ingrained with tools and techniques people can use to learn how to improve their processes (iSixSigma,

1. Six Sigma is a management philosophy that sets objectives, collects data and analyzes results as a way to remove wasted expenses from its processes and help reduce the number of defective products produced. Six Sigma uses quality measures to strive for near perfection by eliminating errors and variables.

The driving factors for a success or failure of implementing Six Sigma is largely dependent on the inputs set forth at the conception and duration of the integration. This whitepaper will compare and contrast these critical inputs for a successful deployment. In order to accomplish this five various companies: GE Electric, W.R. Grace, Royal Chemicals, Diversified Paper and Lemforder. Some of these organizations had very successful results while others failed to reach their full potential. What is clear is the similarities of those that succeed and those that failed.

Six Sigma has produced very successful outcomes in business and industry in terms of their fame in market, profit, customer relation and quality. It accelerates the growth, reduce product cost with an extraordinary increase in profit by eliminating the waste, defects and process line unnecessary steps. Most of the company’s especially manufacturing sector adopted six sigma to improve performance through aim to reduce time and error during each and every step. It also involves large reliability for current and future era with best product quality as well as quality in service and delivery or product with quality.

There are always pros and cons to any quality improvement methodology. For instance, the pros of Six Sigma tend to place extreme importance on leadership and its support for the success of the project. Another pro is the integration of different human elements, which include cultural change, and focus on the customer and their needs. “By using the concept of statistical thinking, Six Sigma encourages applications of statistical tools and techniques that reduce variability” (Harry, 2000). The cons of Six Sigma include, not having the quality data available, especially when a new process has been implemented without having the data available. Often the solutions that Six Sigma proposes can be costly and only a small

Six Sigma is the business strategy and a philosophy of one working smarter not harder.

Six Sigma simply means a measure of quality that strives for near perfection. Six Sigma is a disciplined, data-driven approach and methodology for eliminating defects in any process. In another meaning Six Sigma is a highly disciplined process that helps us focus on developing and delivering near-perfect products and services.

Sigma is the standard deviation (reasonable, institutionalized figure from the mean acknowledgment level), and when the deliberate number of deviations past the mean resilience breaking point is six, you are scarcely creating quality items. Basically, this implies that in the event that you discovered six imperfections in your items, you are near to low quality creation. Regardless of its exploratory methodology towards quality change, there are reactions against Six Sigma. The most vocal one is the perspective that there is nothing but the same old thing new around Six Sigma as it impersonates effectively existing and demonstrated strategies. To a certain degree, this contention has some validity. In any case, advocates of Six Sigma accept that the length of 6 sigma accomplishes more unsurprising results with far lower exertion; there is no damage in tolerating and actualizing it. Reactions in any case, what Six Sigma does is apply deliberate endeavors at using existing strategies with new methodologies Information Retrieved from:

Six Sigma is a business metrics that seeks to identify and eliminate causes of errors or defects as well as failures in business processes by focusing on output that are critical to customers (De Feo, Barnard 2004). It is also a measure of quality that strives to eliminate defects using the application of statistical methods. In this case, a defect is defined as anything that could lead to customer dissatisfaction. Six Sigma’s statistical quality control is the method used to measure variability in a product for evaluation and corrective actions. When the product metrics exceeds the bounds of acceptability, based on statistical inference, the product can be rejected with reasonable assurance that does not meet requirement. It aims to identify and eliminate waste in order to increase speed and flow from start to finish. It also identifies the critical steps, and deleting those not required or nonessential. There are so many metrics process in today’s business industries but the metrics that Six Sigma’s statistical thinking can also be defined as a thought process. In which it recognize the variation is all around us and present in everything we do. The Six Sigma’s interconnected processes and identifying, characterizing, quantifying, controlling and reducing variation provide opportunities for improvement within any organizations or firms. That is to say,

Design can be related to the creation of products goods and services for the benefit of customer satisfaction. When a product is not created effectively the organization could be plagued with costly problems down the line. However, Six Sigma uses tools that will allow companies protection from future problems and widespread liabilities (Kumar et al., 2009). If an organization implements six sigma in well planned out and methodical way, the benefits for the organization could be endless and have a positive effect well into the future of the organization. Therefore, main focus of Six Sigma is to ensure speedy breakthrough performances, substantial financial outcomes, and to have long lasting effects. Another component of Six Sigma is Total Quality Management which focuses things such as strategy, process, and the end

Six Sigma improves the design, the original design business strategies, optimize satisfaction and minimize waste while increasing the financial stability or include monitoring the process of elimination.

Six Sigma aims to establish the causes of errors, measures those errors, and assess them so that they can be minimized. It has five types of examination that aids to solve problems when utilized. These analysis steps include define, measure, analyze, improve and control. The sigma letter is a character that is occasionally used by statisticians to define the variability of any method, particularly the extent of uncertainty with the outcome. There is a big evidence of proof that the use of this process might lead to an enormous minimization of errors in manufacturing, healthcare or any service that is related to the customer. Moreover, the bigger the sigma the fewer the errors permitted. The goal of sigma converts into a maximum of 3.4 defects per every million opportunities, methods, events, proving that it can be used to solve any problem that any product or service fails to meet client’s needs and requirements (Arthur, 2011).

Secondly, the customer focus nature of the measure could present a scenario where customer satisfaction would hold sway over internal control measures, especially for companies working in the service sector. Implementing Six Sigma is expensive often involving training a huge chunk of the companies human resource in six sigma principles this may come at a great cost to the company involve.

The concept of Six Sigma was developed in the early 1980’s at Motorola Corporation (Harry and Schroeder, 2000). Six Sigma can be defined as a statistical measure of the performance of a process or product (Kumi et. al., 2006). It is used as a quality control mechanism, which seeks to reduce defects or variations in a process to 3.4 per million opportunities thereby optimizing output and increasing customer satisfaction (Sambhe, 2012). Sigma is representing the standard deviation, a unit of measurement that designates the distribution or spread about the mean of a process (Six Sigma Academy, 2002). In addition, the Six Sigma uniquely driven by close understanding of customer needs, disciplined use of fact, data, and statistical analysis, and diligent attention to managing improving, and reinventing business processes (Pande, P., et. al. 2000). The Six Sigma methodology uses statistical tools to identify the factors that matter most for improving the quality of processes and generating bottom-line results. The Six Sigma DMAIC (Define, Measure,
