Six Sigma Methodology

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

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).

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 is a systematic and a disciplined approach, a strategy for eliminating the defects in any process like manufacturing, transaction etc. from product to service.

Six-Sigma methodology was applied to single assembly line in order to achieve Six-Sigma levels of quality by trimming down defect level those are crucial to customers. Implementation of Six-Sigma methodology helps to improve levels of overall customers satisfaction through improvements made to the working environment. Discussing the case of implementation the authors in the end concluded that to implement such projects in SMEs, the top management must designate dedicated trained personnel as team members who further provide trainings to workers included in the project in a hierarchical manner. This type of program can be named as Internal Training Methodology (ITM), it also helps SMEs in saving monetary which in case to be paid to consultancies for massive training programs. This type of approach helps organizations to develop new Six-Sigma projects step by step. This type of program helps in render savings and upgrade staff for higher belt levels and then increase the pace of implementation in a phased

Lean Six Sigma can be termed as a program of process improvement that incorporates two ideas which are lean, and six sigma. Lean comprises of techniques for minimizing the time required to deliver services or products. Six Sigma comprises of techniques for refining the quality of services and products, significantly contributing to amplified satisfaction of the client. By incorporating them, Lean Six Sigma can be seen to be a proven strategy of business management that assists organizations in operating more efficiently. Many quality improvement experts and business analysts believe that this program is the most prevalent business performance methodology in corporate developments history (Taghizadegan, 2006).

According to the dictionary, six sigma (sometimes stylized as 6σ) is a set of management techniques intended to improve business processes by greatly reducing the probability that an error or defect will occur. It is becoming a well know and useful strategy worldwide. Every company who needs an excellent management will pay more attention at Six sigma. This essay aims to analyze the case which named Tutorial for IT Call Center and using 10 criteria ways to evaluate six sigma projects.

Six Sigma is a method that provides organizations tools to improve the capability of their business processes. This increase in performance and decrease in process variation lead to defect reduction and improvement in profits, employee morale, and quality of products or services. Six Sigma quality is a term generally used to indicate a process is well controlled (within process limits ±3s from the center line in a control chart, and requirements/tolerance limits ±6s from the center line).

The roots of Six Sigma as a tool of standard measurement can be traced back to the time of Carl Friedrich, who lived between 1777 to 1855. Friedrich introduced the concept that is today called the normal curve. The origination of the Six Sigma measurement standard came way during the time of Friedrich, but it took the Six Sigma format in the 1920s as a genesis of Walter Shewhart who demonstrated that Sigma as from the mean is the location where a particular process is in need of correction. There were other standards of measurement during this time like Cpk and Zero Defects but the coining of the term "Six Sigma" is advocated to a Motorola engineer called Bill Smith (Goldsby & Martichenko, 2005).

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
