Quality Management Techniques Of Six Sigma

While looking to enhance quality levels, a group of Motorola engineers designed a set of quality management tools that utilized statistical data as an approach toward the reduction of defects, and the improved maintenance of quality (Reddy & Hutton, 2013). Focusing on process improvement and variation reduction, Six Sigma uses a measurement-based strategy to improve quality, based on a systematic methodology known by its acronym - DMAIC (iSixSigma, 2012). Once problematic issues are recognized, the DMAIC model strives toward finding a long-term solution through the five phases of defining systems. By measuring key aspects of the current process for data collection, analyzing the collected data and verifying cause and effect relationships, improving current processes from data analysis, and controlling operations to prevent impact in any future process disruptions (Wallace & Webber,

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.

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 focuses on defect prevention; improving quality, cost savings, and reducing waste by helping

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,

Six Sigma is a quality improvement philosophy and a methodology and collection of statistical techniques used to implement that philosophy. Six Sigma’s focuses on reducing or removing identifiable sources of changes in order to decrease the number of defects in a product. Six Sigma was developed by Bill Smith and was used to standardize the way in which defects are tallied (Meredith, 2013). As a new way of doing business, six sigma can have a significant impact on the end result of business. There are many way six sigma can be applied. For example, the scientific component of methodology is a structure approach that takes

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).

The Six Sigma methodology can be described as a management philosophy that focuses on developing and delivering near perfect products services. The approach uses the DMAIC structure and a set of improvement tools to identity causes of variation and to develop improvement strategies that reduce opportunities for defects and variation in process (Galli & Handley, 2014). DMAIC is the acronym for Define, Measure, Analyze, Improve and Control. The central idea behind Six Sigma is that if the defects of a process can be measured, then solutions

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,

A process is any repetitive action, may be a transactional, manufacturing or services. The defects and variation in processes affects productivity, quality and overall customer satisfaction by adversely hitting the bottom line. A new metric was required to measure the defects in processes and a methodology to control the variation in processes. Six Sigma fulfills this requirement of organizations.

Six Sigma is a disciplined, data-driven approach and methodology for eliminating defects (driving toward six standard deviations between the mean and the nearest specification limit) in any process – from manufacturing to transactional and from product to service(iSixSigma:2014)

Quality is a cornerstone of successfully completing a project within the parameters of the project scope. The Six Sigma system improves products or services

The company has demonstrated that Six Sigma could lead to higher quality output, increased productivity, and energised employees. Today, records available in the public domain indicate that more than 30,000 employees have been trained in Six Sigma, with plans to complete GreenBelt training for all salaried employees. Globally, over 11,000 projects have closed and more than 12,000 projects are currently underway. Apart from implementing Six Sigma within the organization, 3M has demonstrated the need to assist their customers in developing creative solutions for their business and manufacturing challenges. Hundreds of 3M industrial business-customer Six Sigma projects have been accomplished. Here, three examples are given of a major automotive manufacturer, a well-known food producer, and a leading manufacturer who had quality problems. The automotive manufacturer had a significant challenge with its largest-selling vehicles. 3M assisted in using Six Sigma to provide a cost effective solution in a short time frame. The well-known food producer needed to keep track of the product that its makes and ships. In the event of a product recall, it needed to locate every food item shipped, right down to the hour it left the production line. With the assistance of the 3M Six Sigma project, 3M-developed
