Study Of B Company’s Project Based Six Sigma Method For Reliability Test Items

Reliability study is to verify the reliability of components, parts and systems within the conditions and time, the ability to complete the required functional capacity studies carried out. Product reliability studies can only be optimized to improve the product in terms of design, materials, manufacturing, technology, equipment, etc., but also reduce input costs, improve product quality and competitiveness, reliability assessment has been to the product as an important quality indicators and testing. In this thesis, taking company B for example, with the Six Sigma quality management methods for reliability testing program in-depth study.First of all, I am related literature conducted in-depth research, understand the current development status reliability and Six Sigma, and research related to the common quality management ideas and methods. After comparative analysis, Six Sigma is not only due to a significant increase in customer satisfaction at the same time will be a waste of resources and costs to a minimum, it is an understanding of customer needs, to regulate the use of facts and data and statistical analysis, as well as management and continuous improvement of business processes to obtain systematic approach to performance excellence performance, so select Six Sigma quality management methods as B’s reliability test project research.Secondly, the principle of electronic product failure analysis, combined with the reliability of the test objects, features and classification, experimental design, this thesis identifies the application of theoretical knowledge; based on this competition agency, the client and the reliability of test items and Company B comparative analysis of the conditions to finalize the evaluation of the reliability test method B company constitute the status.Finally, the use of Six Sigma quality management tools, through DMAIC5stages of work content, combined with the status Company B test reliability analysis to determine the need for both product evaluation system were perfect:one is to optimize the evaluation process, the other side is the test method improvement. After identifying the key factors affecting these two aspect, the problems can be solved and the process can be improved. Through the above work, the subject of tangible improvement in results (evaluation time shortage, samples number reduction, revenue increasing) and intangible improvement effect (evaluation System, reliability personnel, training to improve customer satisfaction) to achieve the optimization of both.
