Research On Identification And Control Of Quality Cost Problems In Enterprise A

Quality is the core element of an enterprise and is crucial for its development.In today’s market,competition is not only based on the price,but also on product quality.With the development of society,the advantage of manufacturing industry to gain market share by the low price is gradually weakening,and consumers’ demand for quality need is also increasing.Improving quality while reducing costs is the primary issue that companies need to solve today and is also the path that manufacturing companies must take to adapt to the market environment and achieve successful transformation and upgrading.To achieve this,companies need to accurately identify the key factors that affect the quality cost of their products.Therefore,the DMAIC method of the Six Sigma management approach is introduced,which identifies the key factors in the defect process through the five stages of define,measure,analyze,improve,and control and then targets them for improvement.This thesis focuses on Company A and uses the DMAIC method of Six Sigma management to improve the quality cost.Firstly,the quality cost analysis method is used in conjunction with the company’s financial data from 2021 to identify the key factors affecting the quality cost inside,which is the rising cost of internal and external losses.The root cause is a low level of quality management,with high defect rates being the main reason.Secondly,the 80/20 rule,causal analysis,and principal component analysis methods are used to identify the four main problems that cause the quality of Company’s products to be substandard:improper employee operations,low equipment accuracy,inadequate employee training,and substandard raw materials from suppliers.These are the root causes of the substandard product quality during the production process and four key factors for improvement using the DMAIC method.Suggestions and measures are then proposed specifically for Company A.Combined with domestic and foreign research results,it is of certain guiding significance to conduct a comprehensive analysis of the quality cost problem of enterprises,through the study of actual cases and combining theory with practice to obtain objective results.Carry out statistical analysis and causal analysis on the collected data,find out the root cause of the problem,and then achieve the research purpose,and finally achieve standardization and systematization to achieve continuous improvement of quality cost.
