The Research Of Quality Cost Improving Strategy In P Company In The Background Of Low Profit

With the development of economic globalization,and the modern revolution of science and technology,especially the development of information technology revolution,and the continuous strengthening of the process of manufacturing industry globalization,Manufacturing Enterprise is facing unprecedented challenges.According to the joint released report < 2016 Global Manufacturing Competitiveness Index >by ChinaInfo100 and Deloitte,in the past over 10 years,China labor cost increased up 5 times compared to 2005.Reduce the cost and improve the efficiency becomes the crucial problem.With the clear known cost of raw material and enterprising service cost,the corporate cost of quality becomes the most important element to improve the competition capability of the company in the market.This paper introduces the cost of quality management development history and key elements firstly,states the enterprise operation impact from cost of quality at different quality management phases.Then,the overall market situation of the lighting industry in which P company is located is interpreted in detail,and the SWOT model is used to further analyze the market competition situation and the overall operating situation of P company.After collecting the quality cost data of P company in 2016,the classification is identified for all the original data,and the statistical analysis is carried out according to the three different dimensions of quality cost,the different phase of quality cost,the source of quality cost,and the quality cost management system,and then observed that in the quality cost management process,there are obvious problems in the quality cost management system,external quality loss cost,product inspection cost,etc.Through the decomposition of the product failure mode,it is found that the external quality loss of P company is mainly reflected in product development.Process,manufacturing process and customer quality management,etc.,and the excessive inspection cost caused by over-testing of products requires more attention to quality statistics and prevention in enterprises,and how to optimize the cost of product inspection by scientific statistics and control.There is a need to improve the quality cost management system to plan and implement all activities related to quality costs.The paper points out the key problems that P company has in quality cost management.Firstly,it is proposed that enterprises need to establish a long-term effective quality cost management system,and gradually improve the quality cost monitoring and reporting system to make quality cost management controllable.Secondly,through the introduction of DFSS model in the product design process,using FMEA tools to improve product quality and reduce post-quality costs,the DMAIC model in Six Sigma theory is used to optimize existing manufacturing processes to improve product efficiency and quality,using the Six Sigma process.The theory of control methods prevents the loss of quality costs caused by product quality problems and reduces the cost of quality inspection through scientific statistical methods.Then,the paper validates the implementation effect of Six Sigma through the quality cost data of P Company in 2017,and finally establishes a complete quality cost management system to solidify the company's process and persevere,so as to achieve continuous improvement of cost reduction and efficiency improvement.Finally,this thesis summarizes the importance of enterprise cost of quality management,and points out the limitations of the paper,which provides a direction for further research.
