A Report On Establishing Quality Assurance System In Manufacturing Enterprise

At present,manufacturing enterprises are entering a crucial period and each enterprise is confronting great changes.In the fields of manufacturing enterprises,especially the automobile manufacturing enterprise,market consumption have become more diversified and personalized and customer's requirement for products is also becoming higher.In this case,manufacturing enterprises should have the management policy of improving products' quality to guide the production and business operation of the enterprise.In terms of quality management,the enterprise needs to establish a set of perfect quality assurance systems to adapt itself to the change of market demand through the advantage of low cost,high quality and high efficiency rapidly and flexibly.Quality is the enterprise survival and development base in the competitive market,and with the DFSK MOTO Co.,LTD.as an example manufacturing enterprises to carry out quality guarantee system research which is the need for manufacturing enterprise to survive and develop.Having a goal of ensuring stability and improving product quality and meet users' requirements,the operation system of quality assurance system is to apply systematic concepts and methods and embarks from the whole enterprise to closely organize the production and business operation activities of each department,in each link and in each stage,to specify their responsibilities and tasks,rights,to formulate the corresponding working standards and operational procedures,to establish information feedback system and gradually achieve systematic organization,institutionalized management,qualified standardization,programmed steps and efficient work,and thus to form a tight,coordinated and effective organic whole.Quality assurance system can help enterprises to improve the customers' satisfaction on products,which is the fundamental guarantee of enterprise to survive and develop,and to improve enterprises competitive ability and quality.To establish the basic method of quality assurance system we can do something as follows:The first is quality improvement process,which is to continuously improve the formal production product.For manufacturing step,quality improving activities mainly focus on the products having been officially produced.And for those who are not,their quality improving activities' process is ruled by the operation system of research and development.From the beginning of formal production to the ending of it,the responsibility of improving products' quality belongs to manufacturing steps.Quality improving process is divided into three steps including problem identification,problem priority and problem improvement.The second one is quality resources' distribution.Quality resource distribution is focuses on reasonable distribution on the quality resources,such as on inspection items,inspection personnel and control method.Quality resources are non-renewable resources;therefore,it becomes important to allocate them.For the same inspection items,in different site inspection,the effectiveness and efficiency inspection is often different.Quality resources distribution has often applied methods such as standard control process,quality control plan and control plan.The third is quality risk control.The key to quality control is to control the quality risk.The most important thing is to identify risks.The quality of the products,in general words,means whether a product is good or bad,and reliable and durable or not.Quality risk is the uncertainty of a product through its life cycle,which also means the possibility of the occurrence of damage and the possible harm produced by it.Since quality is the base of an enterprise to survive,the quality risk control becomes very important.The fourth is practical problem solving strategy.The actual problem solving strategies include PDCA cycle,the six steps of solving actual problem and problem communication report,etc.The fifth one is standardization.Standardization is now a written and best method to complete the work safely and effectively,and is used to achieve a necessary quality level.There is a goal that products,according to cost and regulation of working hours,should be produced to have uniform quality and to fulfill quality requirements in manufacturing plants,and it will be unable to produce products that meet the above purpose if there are some changes in the operation of the manufacturing site such as the order of process,operating method or operating conditions.Therefore,we must lay down and carry out rules on the process,operating method and operating conditions and make them standardized.The sixth is station of quality confirmation.The station is a inspection station used for quality confirmation and set up in the end of the key technology according to the standard quality control process SCP and is to implement standardized examination according to the quality inspection SOS/JES.It may be established by the quality department or workshop.Establishing station of quality confirmation can achieve verification on inspection,feedback,control,and problem resolution.According to the quality inspection of standardized operation SOS/JES,people can complete the key inspection and confirmation,and by passing the problems founded into producing location in time,people can also reduce the frequency of the problems.What's more,the online feedback can not only directly contain defects transmission and recurrence,but also provide data for quality improvement.The seven is vehicles evaluation system(namely VES).Evaluation system is a VES based on customer orientation,adopting the unified standard operating procedures,evaluating vehicle quality according to customers' point of view,pointing out customers' complaints about the poor quality,and passing the feedback to the quality assurance department as basis to improve vehicles' quality.This paper is based on basic guarantee system and analyzes in combination with the practical situation of DFSK.DFSK,founded in 2003,is a company that has three production bases including bases in Shiyan city in Hubei province,in Shuangngfu district in Chongqing and in Jingkou district in chongqing and a vehicle manufacturing plant having stamping workshop,welding workshop,painting workshop and assembly workshop.Though DFSK is only founded ten years ago,it has ranked successfully the top three among mini-cars industry and created the mini-car industry's legend.By the end of 2012,DFSK has a certain degree of increase in economic indicators with 10%rise in output value and 5%rise in total profit.DSFK survives and develops on the bases of quality.In 2012,VES scores of various models dropped 40%,the straight rate rose by 5%,and the qualified rate rose by30%.DFSK,through a decade's efforts,gradually established a quality system,and also accumulated some experience,such as:avoiding deviation in seven drilling improving process,focusing on prevention in the distribution of quality resources,controlling the quality risk loss in the affordable range,following the seven principles when solving practical problem,strengthening the implementation in standardized work,having a standardized test on the execution of station of quality confirmation,and pushing the VES evaluation using specially-assigned person to ensure product quality,etc..At last,this paper puts forward seven Suggestions for DFSK's improvement:The first one is full participation in the recognition of problems and improvement activities.The recognition and improvement of problems is not only the matters of Quality Management Department,but also the whole staff's.The whole staffs participation is good for employees to improve the sense of products quality and responsibility.Employees will identify clearly what's unqualified products and not allowing their entering the next process.The second one is that quality resource distribution should be closely linked with process layout.DFSK will usually not grantee the uniformity of products because of the influence of people,equipment,material,process and environment.Quality resources distribution should be closely linked with process layout when there is some changes in the distribution of quality resource to ensure the high quality of products and satisfy customers' requirements.The third one is to determine the control method according to the process controlling value.For example,this paper set the boundary point of process controlling value as Nol.When the process controlling value articulated equal to or is over No1,then this process has had proper control method.And if not,there is a need to add controlling methods in proper place to ensure the point is equal to over 1.The fourth is to organically combine actual problem solving strategies.When DFSK's problem solving strategies are applied,there are often some problems,such as the form of communicational reports is not unified,there is no efficient cooperation among related departments,and there is also no improving culture established inside the company.In the future,DFSK should organically combine actual problem solving strategies.The fifth one is it is necessary to continuously improve standardized documents.Since the establishment of standardization is applied in certain conditions,it will never be perfect.Thus revising standardization in different situations is a must.The sixth is to build a standardized and communicational platform of quality information.If DFSK want to share its quality information and to improve and push the resolution of problems and communication among employees,it should establish a standardized and communicational platform of quality information.One way is to build sidebars in conformation station.The last one is to make the standardization suitable for market's demand through the market survey of VES evaluation.In order to receive the newest requirements of customers and the quality level or variation of competitive products or potential competitive products,the company needs to revise continuously the standardization of VES evaluation to improve it.To get the newest demands,the easiest and most directive way is to do the market survey of VES evaluation.The above basic methods are independent,yet confluent and together combining a complete set of system and providing methods on quality assurance system.At the same time,with DFSK as an example,this paper makes the other manufacturing enterprises easy to operate and repeat the system.
