Six Sigma Approach

executing Six Sigma in an effective way to solve such complex problems, but also cocoordinating them with other projects and tasks through out the company. In order to

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.

In this document we have done a detailed study of Six Sigma and Lean Six Sigma and how they help Business Analysts to maximize their skill sets to attain maximum process improvements in their activities. We introduce the topic, provide a historical timeline and disucuss its relevance to the topic. After that, we analyze current state and use the information to provide results in Analysis and Synthesis section.

In this case study of an Aircraft Manufacturing Company there was an issue regarding the delivery of the upper door to the final assembly. By applying different six sigma tools like Process mapping, Pareto chart they came to know that there was a problem in three different sectors of the company and the six sigma team of the company implemented cause and effect diagram to analyze the main root cause for the problem and they came out with a result that the door handling

For these reasons, the catapult (Figure 2) set was suggested as a primary training aid in the Six Sigma training. A catapult offered a tool/process that enhanced the learners’ understanding. It supported up to seven factors at two or more levels of experimental design as well as both continuous and categorical factors. It provided data for analysis, which could be used for Gauge Repeatability and Reproducibility (GR&R), Hypothesis Testing such as t-test, one-way ANOVA, Regression, Design of Experiments (DOE) and Statistical Process Control (SPC). A good tie-in between the Six Sigma competition game and the Six Sigma topic was desirable to motivate and ensure engagement during the class. The learners were able to practice the Six Sigma

First, The Six Sigma, usually intended as a professional plan, includes refining, scheming, and monitoring procedure to minimalize or remove excess while enhancing gratification and increasing financial steadiness. The performance of a procedure—or the process competence—is used to ration enhancement by associating the baseline process competence (before development) with the process competence after directing possible solutions for quality development.

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,

One of such strategy is the implementation of Six Sigma methodology in the organization. Six Sigma is a methodology that combines the gradual and continuous improvement with radical redesign. The process of Six Sigma begins by measuring the statistical variability within a process. This means that the causes of error can only be determined if you understand the critical requirement of either the internal or external customer. Six Sigma processes are designed to reduce process variability. Six Sigma helps the organization to achieve improved process flows and better

Background to Six Sigma The contemporary business environment is rapidly evolving. With the increased impetus toward globalization, organizations are undergoing continuous and rapid change driven by increased consumer expectations, the advent of new technologies, and the very real prospect of global competition (Bendell, 2005). This has resulted in a dramatically different business environment in which the modern business, in order to survive and prosper, is forced to evolve and regularly revise their internal and external business processes. One of the tools that was developed to aid in this change process was Six Sigma.

Since the core of Six Sigma management is quality, it is consistent with lean thinking. Use lean thinking which is focusing on eliminating waste and identifying improvement. When fused with the main elements in lean production, such as 5S system, TPM, stability and standardization6, the Six Sigma production system can be better operated. Quality can prove its own value only if product can best serve customer and provides benefits to shareholders, so when comes to the quality issue, doing statistical analysis about the customers’ demand and company’s goals is essential for the “master black belt” and “black belt ” to lead teams to right places.

Six Sigma is a business technique that helps to continually identify and reduce the process variations or failures to achieve desirable results (Vora & Ravanan, 2014, p. 1). The organizations will be able to minimize the gap of customer expectation and product attributes. There methods being used in Six Sigma are “DMAIC” (Design, Measure, Analyze, Improve, and Control) and “DMADV” (Design, Measure, Analyze, Design, Verify). Besides, Design for Six Sigma (DFSS) is also a methodology used in Six Sigma to create lesser defect products, processes or services based on customer requirements. DFSS to achieve minimum defect rates during the development stage of the product. Thus, better quality of product or services can be produced by the organizations to increase the customer satisfaction. All of these methodologies give a big benefit in

It can be concluded that use of the Six Sigma DMAIC approach was successful in identifying the problem, improving the process, and controlling the defects

The second criterion is the application of Six Sigma tools. According to the case study, it thoroughly follows the DMAIC ways. We can evaluate the project utilizes the Six Sigma tools correctly on the five phases. In the defined phase, the SIPOC diagram shows suppliers, inputs, outputs and customers using flowcharts of the overall business process. The measure phase utilizes a process map to demonstrate the timeline and the process steps for a release cycle. Six sigma team also utilize chart to show issues. In the analysis phase, the team adopts a Cause-and-Effect diagram to explain delays in Cycle Time, and draws a chart to show the results which would cause due to release delay. Finally, they used a run chart in the control phase to demonstrate the how errors improved. This study used the tools in the Six Sigma appropriately and also used the Six Sigma

Beside the customer analyzes, six sigma can also help Forefront to carry out its work more efficient at a higher quality level.

The first year of deployment was extremely difficult for Six Sigma success. They decided to select the project on the basis of high probability of their success and targeted to complete them in a short period to assess the success. These projects were treated as pilot projects with a focus to learn. For the selection of the right project the field data was collected, process map was developed and the importance of the project was judged from the eyes of customers.
