Causes and Effects from Case Studies Essay

Originally, Six Sigma was designed for control of defects and was part of total quality management (TQM) (Gupta, 2003). Since its creation, however, it has gone well beyond what it was originally. It is much more of a methodology now, and used to address and handle the variations that are seen in processes. These variations can cause defects, and that makes them unacceptable deviations that stray too far from the mean. When the variations can be managed systematically, the defects will be largely eliminated from any product (Gupta, 2003; Whalen, 2002; Witt, 2002). Because of that, the Six Sigma objective is to provide performance, value, and reliability to every end user or customer on a level that is world-class. Through the years it has gotten much better at meeting that objective, and more companies have began adopting it. One such company is Cessna. The company makes airplanes and airplane parts, and its name is almost synonymous with small, personal aircraft.

• Six Sigma affords the avoidance of a “hit and miss” approach by breaking into measurable bites an entire chain of events leading to a problem, and then coming up with a corrective action (Roff, 2005, p. 1). According to Bateman and Snell (2009, p. 582), the acceptable failure rate is “99.99966 percent level of accuracy.” Although Six Sigma is a powerful control mechanism, it takes about 2-3 years from the time of implementation until its development is fully realized. It is a method that is most useful to a company when it is tailored specifically to a company’s processes.

Six Sigma was first introduced in the 1980’s by none other than Motorola. It was not however necessarily a novel concept at the time so much as it drew from a conglomerate of proven manufacturing principles. It is strikingly similar to the scientific method in design. Six Sigma approaches areas that may not necessarily be viewed as problematic with an open mind. It seeks to analyze problems or questions with a stepwise, statistical, and quantitative focus in order to discover, fix, or disprove problems that may or may not exist within a process. By doing this Six Sigma can improve efficiency and therefore improve positive outcomes for whatever the endpoint may be (Mast, Bisgaard, & others, 2007).

Six Sigma is a process improvement initiative developed by Motorola that assist organizations in identifying and reducing defects and inefficiencies within their existing business processes. The quality management system is a project-oriented system that drives cost savings and increases firm’s profitability by reducing variation in firm’s processes, products and services. (Russell, 2011). The process begins with four steps align, mobilize, accelerate and govern. Companies begin aligning by constructing company-wide metrics surrounding financial and strategic goals of the organization. These metrics are used to determine the area of the business that requires the most improvement and would have the largest financial

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,

Lean Six Sigma approach is recognized widely and has been implemented predominately in manufacturing rather than other industries. To illustrate the point, this paper draws attention to the adoption of Lean Six Sigma in various industries with a case study. The combination of Lean tools and Six Sigma methodology is used to improve the process and quality by eliminating the variations and creating workflow in a process. The hypothesis of this study was that the Six Sigma technique can be used along with lean tools in order to improve process and quality in any area of industries. The review of case study discovered the use of

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

This case study deals with improving the process and efficiency of the operating room in a hospital. The problem was resolved using a Six Sigma DMAIC problem solving methodology. The basic equation of Six Sigma, Y = f(x), defines the relationship between a dependent variable ‘Y’ or the outcome of a process and a set of independent variables ‘x’ or possible causes which affect the outcome.

The six sigma Black Belt has found and accepted all known underlying drivers for the current open door. The six sigma methodology obliges Black Belts to distinguish arrangements. Couple of thoughts or opportunities are good to the point that all are a moment achievement. As a major aspect of the six sigma approach there must be checks to guarantee that the coveted results are being accomplished. A few investigations and trials may be needed with a specific end goal to locate the best arrangement. At the point when making trials and tests it is imperative that all task partners comprehend that these are trials and truly are a piece of the six sigma

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

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 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

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

Six Sigma 's most central and got a handle on structure is its critical sense DMAIC approach. This upgrade takes after the framework and its sporadic state stray pieces, given that the necessities depict the best deliverables, which deal with the endeavors and the contraption decision to help in the errand. The DMAIC approach is required to consider flexibility and iterative work, if principal. As more is found through the 5-make process, demand or theories concerning the key driver of the issue may be reproved, requiring the wander get-together to come back to them and modify or to research elective potential outcomes. For case, control driver to a business oblige fittingness issue may have been considered as an attracting system issue in a specific geographic district. As denied to making a surged judgment without presumptions by executing another business plan program, the Six Sigma increment securing respectably proposes substances about the issue first. After some examination and examination, the gathering finds that the secured driver centers to an issue with layouts organization together heading, not nonappearance of offers strengths ' data and aptitudes. In the occasion that the wind wrap followed up on the key supposition, time and money would have been abused on working up a frustrated approach that would have made poor results; the get-together 's beat work would have gone to squander. Rather, the party did a mid-course upgrade in light of truths, adjusted its
