1. Topic of meaning and context选题的意义和背景
Advances in technology make today's world of rapid economic development , companies want to remain invincible in the fierce competition, only constantly improve themselves and enhance their competitiveness , so more and more companies and organizations turned their attention to the introduction of advanced management models and methods to improve product and service quality [ 1 ] . Among the many methods , 6Sgima Management Act can be fruitful result comes as a method , it can help companies improve quality from all aspects of the critical processes , while significantly saving costs.
Quality is the lifeblood of a business , is fundamental for the survival of the enterprise , our company 's quality policy is : a comprehensive quality control, and implementing the system , provide quality customer demand ; full participation, in time, to achieve the goal of zero defects . 6Sgima as an innovative quality management model, since the United States made by Motorola in the business world more and more attention and recognition. Many multinational companies are 6Sgima as a strategic enterprises and the introduction and promotion. Some of our walk in the forefront of quality management and medium-sized enterprises have begun to target the 6Sgima promote quality management [2 ] . Therefore, how to improve the quality of the products is a top priority , the topics to 6Sgima management model to improve the quality of the product - process capability study is significant.
6Sgima in the mid -1990s began to be GE from a total quality management approach evolved into a highly effective business process design , improvement and optimization technology, and provides a series of equally applicable to the design, manufacture and service of new product development tools. Then with GE globalization , service-oriented e-commerce strategy go hand in hand , becoming the world's pursuit of excellence in corporate management of the most important strategic initiatives. 6Sigma gradually developed into the main customer to determine the strategic objectives and product development and design of the scale , the pursuit of a management philosophy of continuous improvement [ 3 ] . 6Sgima summed up the successful experience of total quality management , process management, the essence of which refined techniques and the most effective way to become a way to improve business performance and competitiveness of the management model. This management method in Motorola, General Motors, Dell, HP , Siemens, Sony, Toshiba 's line of many multinational companies proved to be fruitful .
With the development of science and technology, the quality of people's increasing demand for the product , the quality of knowledge is also improving. Initially, people generally believe that product quality is measured by the instrument , improving manufacturing technology to make people believe that product quality is the turn out of the machine-made , after experiencing large- scale production, people began to realize that the quality of products must rely on a comprehensive quality management to ensure . In the machinery manufacturing industry, in order to achieve customer satisfaction and continual improvement , designers can design according to customer needs the product to meet customer demand , the results of the manufacturing sector is based on the design of production to meet the requirements of the product [ 4 ] . But to meet product requirements rely solely on processing procedures is not enough, more is to manage a large number of quality production processes , to reduce substandard goods, defects or errors in the work to a minimum, while 6Sgima is basically a process of quality objectives , is one of the key elements of reliability , it is actually far beyond measure , verify and isolate the defective product , but represents a change in traditional practices, is a new management approach , emphasizing the involvement of employees at all levels , is a customer-centric , data-based , using statistical methods to pursue business management ideas perfect target [ 5 ] . By correctly identifying customer needs , workflow reengineering and other measures to improve the management of innovation advocacy core competitiveness of enterprises ; to measure the DMAIC problem by establishing a logical model , analyze the causes , improving and monitoring the effect of the optimization process , the enterprise product manufacturing capacity to achieve the best aspects of the process . It is in this context, I chose this topic , as well as help to improve the quality of the research objectives machinery manufacturing industry products.
