...Sigma Significance of Six Sigma By Suhasini Pratapagiri Stratford University INTRODUCTION: WHAT IS SIX SIGMA? Six Sigma is a highly disciplined process that helps a company focus on developing and delivering near perfect products and services. Six Sigma at many organizations simply means a measure of quality that strives for near perfection. 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. The fundamental objective of the Six Sigma methodology is the implementation of a measurement-based strategy that focuses on process improvement and variation reduction through the application of Six Sigma improvement projects. This is accomplished through the use of two Six Sigma sub-methodologies: DMAIC and DMADV. The Six Sigma DMAIC process (define, measure, analyze, improve, control) is an improvement system for existing processes falling below specification and looking for incremental improvement. The Six Sigma DMADV process (define, measure, analyze, design, verify) is an improvement system used to develop new processes or products at Six Sigma quality levels. It can also be employed if a current process requires more than just incremental improvement. Both Six Sigma processes are executed by Six Sigma Green Belts and Six Sigma Black Belts, and are overseen...

Design/methodology/approach – A specific research question is: does learning mechanisms and continuous improvement practices support each other and how, and what type of learning can be identified in the improvement of business processes. The question is linked to one of the fundamental issues currently discussed in the field of organizational learning; how do organizations get “from here to there”, in other words, what is the dynamics of the processes of learning and how progressive learning is achieved. A case study of a few Finnish companies is made and a procedural implementation model is applied. Findings – The findings suggest that the learning process is characterized by measurement, detection and correction of errors, and cost reduction. In six sigma implementation, learning is a single-loop type of learning. It is an incremental change process which reminds a technical variant of the learning organization...

... 6 SIGMA In 2001, Caterpillar launched its 6 Sigma program to drive change to achieve the company’s long-term strategic goals (Caterpillar uses 6 Sigma to identify its Six Sigma initiatives). This 6 Sigma process was, and continues to be, extremely successful. Some of the results include first-year benefits that exceeded implementation cost and achievement of the revenue goal two years earlier than planned. We’ll briefly discuss Six Sigma in general, describe Caterpillar, and show the entrenchment of 6 Sigma within the company’s strategic planning process.

Six Sigma is a total quality management (TQM) technique pioneered by and applied to Motorola processes in the 1980s by Bill Smith, a Motorola engineer who became known as “the father of Six Sigma.” Since then, other companies, such as Bank of America, Honeywell International, Raytheon, and General Electric, have taken these learned processes and expanded them. Even though many people have reservations about the potential savings from Six Sigma, a story by Charles Waxer (“Six Sigma Costs and Savings: The financial benefits of implementing Six Sigma at your company can be Significant,” www.isixsigma.com/index.php?option=com_k2&view= item&id=1228<emid=187) reports that GE saved more than $12 billion over five years, Honeywell saved $800 million, and Motorola saved $15 billion over 11 years.

...Six Sigma is a revolutionary business process geared toward dramatically reducing organizational inefficiencies that trans- lates into bottom-line profitability. It started in the 1980s at Motorola; then, organizations such as GE, Allied Signal, and Seagate worked with the initiative during the 1990s and made it the most successful business initiative of the era. Key to the Six Sigma methodology of the 1990s is a five- step process—Define, Measure, Analyze, Improve, and Control (DMAIC). By systematically applying these steps (with the appropriate tools), practitioners of this approach have been able to save substantial dollars. The basis of Six Sigma is measuring a process in terms of defects. The statistical concept of six sigma means our processes are working nearly perfectly, delivering only 3.4 defects per million opportunities (DPMO). Sigma (the Greek letter σ) is a statistical term that measures standard deviation. In the context of management, it’s used to measure defects in the outputs of a process and show how far the process deviates from perfection. A one-sigma process produces 691462.5 defects per million opportunities, which translates to a percentage of satisfactory outputs of only 30.854%. That’s obviously really poor perform- ance. If we have processes functioning at a three sigma level, this means we’re producing 66807.2 errors per million. Figure 1-1. DPMO at sigma levels nities, delivering 93.319% satisfactory outputs...

...on the process i.e., improved quality, delivery and cost performance has emerged. This has led to the introduction of Lean Manufacturing which focuses on waste elimination and creation of flow within an organization. In the words of Shigeo Shingo “The most dangerous kind of waste is the waste we do not recognize.” Lean and six-sigma are methodologies backed by powerful tools that help in improving quality and productivity thereby improving overall profitability and competitiveness. The lean philosophy was initially pioneered by Toyota manufacturing company and aims at various methods of eliminating waste and improving the process flow. Six Sigma on the other hand, focuses on reducing variation using problem solving and statistical tools. It was first implemented in the Motorola Company as a safety margin for product performance. SIX SIGMA Six Sigma is a continuous improvement strategy that focuses on minimizing defects and variation and aims at achieving 3.4 defects per million in productions, design and process flow. Six Sigma minimizes variation in the process flow, thereby improving customer satisfaction. Benefits of implementing Six Sigma methodology are as follows: a. Better knowledge of products and processes b. Defect reduction c. Focus on communication and teamwork d. Improved customer Satisfaction e....

To improve product cost, scheduling, quality, and performance, General Dynamics Mission System have deployed an active Lean Six Sigma program. Lean Six Sigma is a combination of two processes, Lean and Six Sigma. Lean is a systematic method for the elimination of waste. Six Sigma is a methodology for eliminating defects, mistakes, or failures in business processes. Both processes are a set of principles aimed at continuous improvement. Lean Six Sigma has become a popular technique for deploying continuous improvement in the manufacturing arena, but not all companies have successfully benefited from the Lean Six Sigma process—mainly due to poor execution. Jeyaraman and Teo (2010) “A Systematic Review of Lean Six Sigma for the Manufacturing Industry” and Albliw, Antony, and Lim (2015) “A Conceptual Framework for Critical Success Factors of Lean Six Sigma” contains comprehensive research studies in the functional area of Lean Six Sigma.

...| Quality management techniques | Assignment II | Deepali Jain Roll No. 303 MBA Tech Manufacturing | Quality Management Techniques Quality management can be considered to have four main components: quality planning, quality control, quality assurance and quality improvement. Quality management is focused not only on product/service quality, but also the means to achieve it. Quality management therefore uses quality assurance and control of processes as well as products to achieve more consistent quality. For Factual approach to decision making quality improvement techniques are used. Effective decisions are always based on the data analysis and information. PDCA cycle PDCA (plan–do–check–act) is an iterative four-step problem-solving process typically used in business process improvement. It is also known as the Deming circle, Shewhart cycle, Deming cycle, Deming wheel, control circle or cycle, or plan–do–study–act (PDSA).

...The DMAIC is a core component of the Six Sigma methodology and is a structured problem solving process which provides all employees with a common language and a set of tools to communicate with each other, particularly as members of cross-functional teams, and is considered a roadmap for conducting a Six Sigma project. It is used when making improvements to an existing process. 1. Define – Define is the first step in the process. In this step, it is important to clearly define the problem. One must describe the problem in operational terms that facilitate further analysis. 2. Measure – The Measures stage (which is the most time-consuming part of the DMAIC methodology) focuses on how to measure the internal processes that affect CTQs. It requires an understanding of the casual relationships between process performance and customer value. 3. Analyze – Collecting data is simply not enough. The Analyze phase focuses on why defects, errors, or excessive variation occur. After potential variables are identified, experiments are conducted to verify them. Analysis reveals whether or not a problem is real or just a random event. 4. Improve – The improve stage focuses on idea generation, evaluation, and selection. Once the root cause of a problem is understood, the analyst or team needs to generate ideas for removing or resolving the problem and improve the performance measures and CTQs. 5. Control – The Control stage focuses on how to maintain the improvements, which includes...

The Six Sigma DMAIC processes (define, measure, analyze, improve, control) is an improvement system for existing processes falling below specification and looking for incremental improvement (Unknown). DMAIC is a primary theme within Six Sigma. This theme is used to identify issues and rectify them. Using this methodology helps address issues at the front of the process as soon as they come up which can then fold into preventing problems before they appear or get worse. Six Sigma is a tool not a cure (Bangert, 2014). DMAIC is an acronym that stands for define, measure, analyze, improve, control. An in depth breakdown of this process is that it is data driven, and can be implemented in conjunction with Six Sigma or as a standalone quality improvement measure. The breakdown is this: define the problem, improvement activity, opportunity...

...Quality Improvement: Six Sigma Individual Paper, Unit 6 Revised Research Paper Shelli Cornwell scornwell@capellauniversity.edu BUS3004 Developing a Business Perspective 12/18/2011 Introduction The primary focus of this paper is to introduce ways to incorporate quality improvement within an organization. Quality matters when servicing members, providers, employees, groups, brokers, etc. Ultimately, customers do not care about great productivity rates when on the receiving end of quality errors. Measuring quality throughout an organization should be the number one focus. There are many quality management tools available to an organization; however; Six Sigma is a strategy that many world class organizations have implemented to improve quality, service and customer satisfaction. The word Sigma is a statistical term that measures how far a given process deviates from perfection. An organization as a hole needs to embrace feedback on errors and determine solutions to these areas for improvement. And above all, there must be a better balance between productivity and quality. “Six Sigma improves production quality by removing variables that can cause defects” (Brinlee, n.d.). When a customer has to continuously spend time on the phone or in writing to have an issue resolved, this becomes frustrating to customers. When an organization has displeased customers due to defects in the quality of service, this can ultimately have an enormous impact on the reputation of an organization...
