When you think of Six Sigma, what comes to your mind? I believe that most people will think that Six Sigma is very complicated, elusive and even a bit illusory. Many people have also talked about Six Sigma and become disillusioned, thinking that it is a height that cannot be reached. China Manufacturer of metal flange
The name 6 Sigma is derived from the traditional terminology of statistics. 6 Sigma means that there are 6 standard deviations that can be squeezed in between the process mean and the customer specification.
1 Let’s take a simple case to understand what problems Six Sigma can help us solve.
People waiting for the bus always hope that it will arrive on time, and the psychology can tolerate a 2-minute error in the arrival time. Assuming that the expected (target) time is 14:11, the upper and lower limits of the specification represent customer satisfaction. Collecting the arrival time of trains for seven consecutive days, the average is just 14.11 points. Let’s take a guess. Will people waiting for the subway be very satisfied? Maybe no, what customers experience is not the average. If the bus arrives early, customers will miss it, while late arrivals increase wait times and can affect commute times, resulting in late arrivals for work. China Manufacturer of metal flange
If every time customers take the bus, the vehicle arrival time can meet their expectations. That is to say, the process of achieving the goal and the actual process becomes worse, so that the time value of each arrival is infinitely close to the goal, so that the customer can be satisfied. From the customer’s point of view, they always want to pursue perfection, products without deterioration, and zero defects. And 6sigma is an improved method that helps us produce and deliver near-perfect products and services.
Why get to six 6sigma, not 3, not 4? 6sigma means: There are 6 standard deviations that can be squeezed in between the process mean and the customer specification, and the actual delivered product output does not exceed the customer specification, achieving a near-perfect process output (zero defects).
2 The three focal issues that Six Sigma pays attention to are: customer satisfaction, speaking with data, and process. China Manufacturer of metal flange
Focus 1 What are the factors that affect customer satisfaction (CTS)?
What do customers expect? What is the voice of the customer? To satisfy customers, for example, what are the essential features of a speaker, what functions can meet the special needs of customers, and what can surprise customers? Enterprises need to consider CTQ, CTD, and CTC. Key customer needs.
Focus 2 speaks with data.
Data in any analysis of a product drives decisions and actions. Without data, there is only experience, and making head-scratching decisions will lead to wrong decisions, or even a series of wrong actions; only collected data without sorting out, can’t make clear and effective decisions. The collected data is classified and summarized, and statistical methods such as DOE, regression analysis, capability analysis, and normality detection are used to measure and analyze the central tendency of the data, so as to find the optimal design and decision-making.
Set point three process.
The customer is concerned about the product (speaker), so the speaker production process is a process from the customer’s point of view, and the sub-processes of installing magnets, magnetic sheets, dust caps, supports, voice coils, gluing, and drying are to deliver the speakers. The Sigma improvement process is an important process that customers focus on. Our production process strictly manages each sub-process, so that the action process of ‘from the inside to the outside’ is from the customer’s point of view. China Manufacturer of metal flange
The difference between Six Sigma and traditional problem-solving methods is to explore deep sub-key factors to find the key factors X’s that affect Y; to reduce the variation and achieve the goal by eliminating the root cause X or determining the best factor. Finally, lock the results in the control measures to maintain the results. China Manufacturer of metal flange
