It is based on the philosophy that the ideal way to cut down cost is by reducing defects. The goal of Six Sigma is to reduce variation for optimal quality control. Brainstorming is essential for generating information for other six sigma techniques like 5Why, FMEA, Fault Tree Analysis and the likes. The structure followed passes through five important phases DMAIC. Identifying the root cause of variations (defects). Teams and leaders should be appointed and trained in. Since sigma is derived from standard deviation, the concept of six sigma seeks to reduce deviation to the barest minimum. When a customer is not satisfied with a product, it means the product has a defect and according to six sigma this defect has to be eliminated so that superior quality of goods and services can be manufactured and delivered. These principles were employed by the company to bring down the defect rate in their production line. This involves Design of the procedure ensuring customer satisfaction, Measure the parameters required for quality maintenance, Analyze so that an alternative is always present to maintain the superior quality, Design of the details and finally Verify all the processes before implementing them. Hence, six sigma emphasises on meeting and exceeding the expectations and needs of customers. The Six Sigma management method philosophy focuses on better understanding of customer requirements, improving business systems throughout the organization, and enhancing the organization's financial performance. 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. In today’s technological age, information spreads like wildfire. Likewise, the organization achieves optimum results. Six Sigma Principles. Six Sigma is a methodology that primarily focuses on eliminating defects in the business process. Because of the versatility of the method, its definition may vary.

Six Sigma principals are being introduced by companies today to lower the defect rate to a minimum. Six Sigma is not a completely new way to manage an enterprise, but it is a very different way. A team has to collect data on the current process that is being performed. This six sigma technique is also known as potential failure and effects analysis or Failure Modes, Effects and Criticality Analysis (FMECA). Quality expert Joseph M. Juran described Six Sigma as "a basic version of quality improvement", stating that "there is nothing new there. Six Sigma helps to develop well-organised processes while achieving high-quality products. Six Sigma is a disciplined, statistical-based, data-driven approach and continuous improvement methodology for eliminating defects in a product, process or service. This is where six sigma really helps. Since the customers are the final consumers, this concept ensures that organizations tailor all forms of improvement to suit their customer’s preferences. Motorola was the first company to introduce Six Sigma methods in its manufacturing process. On the other hand, Design for Six Sigma is another name for DMADV. It is a data-driven approach that uses a statistical methodology for eliminating defects. Lean Six Sigma is a powerful, proven method of improving business efficiency and effectiveness. Generally, organizations apply this technique when defining a new process, launching a new product or increasing sales. However, brainstorming in the six sigma process is more complex. So, it can be said without a doubt that to remain in that position quality of the product is of prime importance, and secondly comes the price. These are used in the six sigma process to outline an existing process in a simplified way. When there is so much competition, one cannot afford to lose a single customer as he will move on. Consistency leads to quality. Six Sigma is a data-driven methodology that provides tools and techniques to define and evaluate each step of a process. So, six sigma is plus/minus three sigma from the mean (average). On the other hand, six sigma executives and champions provide administrative support during project implementation. Whenever this six sigma project is implemented in any department of a company, well-constructed steps are taken and targets are undertaken to improve production. Six Sigma is a quality-control methodology developed in 1986 by Motorola, Inc. This technique is used in the six sigma process to understand customer’s needs, expectations and experiences. Six Sigma principles are: All business and manufacturing processes come with a set of characteristics that can be analyzed, controlled, defined, and improved; Consistency plays an integral role when it comes to reducing process variation, which contributes to the viability of businesses As we finally made our place in the world market. Nevertheless, the six sigma concept did not originate to benefit organizations alone. They've adopted more flamboyant terms, like belts with different colors. The concept of six sigma is to improve productivity and profitability. Thirdly, outputs are the end products, service or information. It is used to detect likely errors that might occur in a product, service, process or design. In 1986, in response to increasing warranty claims, senior engineer Bill Smith introduced the concept of six sigma, as a way to standardise defect measurement. Motorola and Bill Smith developed this concept when they were facing a lot of competition and today it has become a Go-To concept adopted by many companies namely, Infosys, Tata Consultancy Services, Wipro, Ford, Boeing, to name a few. The best way to know the “voice of the customer” is through direct conversations and interviews. First and foremost measuring the current variation is of utmost importance.
