Shanghai Mobile Communications market is highly competitive , D Company P system because of low rates and low radiation , once on the market plays an important role. However, with lower tariffs competitors , P declining competitiveness of the system , combined with its technical birth defects, churn rate has been rising. This article relies 6Sigma principle, the use of various 6Sigma quality management tools , trying to improve network quality , improve customer satisfaction , thereby reducing churn , create benefits for enterprises . In this paper, 6Sigma principle, Company D P system user complaint rate remains high because the situation analyzed, and results of the analysis , formulation and implementation of appropriate measures , and ultimately reduce the rate of user complaints . Through this research project , the following conclusions: one , 6Simga quality improvement programs commonly used in manufacturing and other service industries , telecom operation to improve network quality using the 6Sigma not many precedents , through this 6Sigma successful project implementation to prove 6Sigma apply to the communications network maintenance and management work to improve network quality . Second, according to the quality management DMAIC 6Sigma five steps , starting from objective data by measuring , analyzing , improving and other various stages of measures to improve the network quality , and take this enhanced network efficiency. Facts have proved that objective and reliable data and rigorous workflow is the key to complete the task . Third, when the quality to a certain extent , we must continue to rely on to improve the quality of DMAIC very difficult , so you must consider using DMADV model improvements. And the model can be applied TRIZ is an effective tool , with TRIZ can further improve network quality . The subjects of 6Sigma tool to improve the quality of the communication network used by telecom companies is not much , but the use of TRIZ theory to improve the quality of the network is also an exploration of the first , so on paper from the process to improve the quality of the telecommunications network to provide new ideas and solutions program , has some practical value.
