Statistic Methods: Utilizing Six Sigma Essay

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.

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 measurement based strategy for process improvement and problem reduction. It is completed through the application of the Quality Improvement project and accomplished with the use of two Six Sigma models. One model is DMAIC (define, measure, analyze, improve, control), which is designed to examine

Six Sigma methodologies focuses on reducing variation to eliminate defects and have a standard output with less inventory (Kubiak & Benbow, 2009). Implementation of Six

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,

Six Sigma was established by Motorola in 1987 as a strategic initiative. Since then, it has been deployed in a growing number of global firms. The initiative was specifically designed to attack any problems derived from variation, both by reducing variation as well as by improving the

Six sigma intention is to eradicate wastage, ineffectiveness and in efficient processes and to increase customer satisfaction by facilitating customers in a way they expect.

The name Six Sigma was originated from the Greek letter sigma, which has a function of denoting variation from a certain standard. In statistics, the word sigma measures how much is the distance of a certain process with perfection. The main idea of Six Sigma is that if the “defects” or flaws of a certain process can be defined, then it is certain that the aforementioned “defects” and flaws can be eliminated in order to achieve perfection or the stage of “zero defects”. In order to achieve the aforementioned goal, a process must be able to produce no more than 3.4 defects per million opportunities. An “opportunity” in this case is defined as a moment of

Six Sigma attempt to identify and remove the causes of defects and errors in manufacturing and business processes. It uses a set of quality management methods, including statistical methods, and develops a special infrastructure of people within the organization ("Black Belts" etc.) who are experts in these methods (Harry, 1998). Project of Six Sigma project follows a pre - defined sequence of steps and has project

The basic principle of improvement by the processes of Six Sigma methodology is by the reduction of diffusion. The six sigma approach aims to reduce defect levels to only a few parts per million for an organization's key products and processes. The Six Sigma philosophy is based on the fact that all processes from design, through to manufacturing and to services provided to customers, display aberrances, which may result in product errors that cost time and money. These errors are variations of processes that can be reduced by various methods in order for the real cause of the problem to be systematically identified and

If the cost of quality is high, looking through the Six Sigma, the cost of poor quality is still higher. Companies bear a huge cost of about 9-16 percent of their revenues on problem solving.

As explained by Kumar and Kaushish (2015), Six Sigma is a “disciplined data-driven approach and methodology for eliminating defects in any process” (p. 7). Six Sigma stresses the reduction of variation within processes by identifying and eliminating the root causes of defects (Jayaraman et al., 2013; Kerzner, 2013; Kumar & Kaushish, 2015). The goal of Six Sigma is to get as close to zero defects as possible. The term Six Sigma comes from the Greek letter σ (sigma) which in statistics represents one standard deviation (Ismyrlis & Moschidis, 2013; Kumar & Kaushish, 2015; Mădălina, 2014). Six Sigma, or six standard deviations, yields a

The Six Sigma improvement method is problem-focused and its main objectives are decreasing scrap, earning income and creating value (Saghaei et al, 2012). Motorola developed this concept in 1986. There were three meanings of six sigma provided by Brue (2006). It is the level of quality that a process assures, it is a problem solving methodology and lastly it is a management philosophy. Alternatively it is also said to be a project driven approach to process and product quality improvement (Ray and Das, 2010). This approach ensures the process to be 99.9996% defect free. The performance level of a project can be obtained by subtracting the average of readings of errors in a process from the given specification

Definition of Six SigmaSix Sigma is not a mere methodology or a quality tool. It is a philosophy i.e. a systematic way of thinking to solve quality problems. Six sigma involves
