Sustainable Quality Improvement Projects Of BYQ Company Tank Shop

Products quality is guaranteed only through production processes, and sustainable improvement of processes deviation, cycle time and output are significant to cost reduction and revenue improvement. This paper mainly research how to Take full advantage of various quality tools, including work-site management 5S, traditional seven quality tools, process capacity analysis, poor quality cost analysis and more complicated statistics factorial experiment and variance analysis, to lower products cost and improve revenue through process deviation reduction, process cycle time reduction or process output improvement.This paper makes concrete analysis from following aspects in conjunction with tank shop situation of BYQ Company. First through poor quality analysis, conclude that it is necessary to strengthen quality inspection and quality control so as to reduce internal and external failure cost; second through sorting and analysis of all non-conformance records happened before quality sustainable improve approach, make us understand it is crucial to strengthen quality sense, enhance bottom management and improve process capacity; third through analysis of previous year compound quality level before quality sustainable improve approach, point out the compound quality level gap between BYQ tank shop and counterpart, make us feel quality crisis; last in connection with BYQ Company production volume development target, conclude it is inevitable for BYQ Company to select the development pattern of reducing cycle time and improve output. Focusing on above analysis and basic quality sustainable improvement theory and various quality sustainable improvement tools, from three aspects this paper describes tank shop's vivid and dramatic quality sustainable improvement approach. First, in conjunction with tank shop concrete production processing follow, strengthen employee's quality sense, self-inspection and mutual inspection through use of scientific inspection card covering tank shop whole production chain; second, adopt scientific work site management 5S featuring tank shop concrete situation and work site inspection card to strengthen tank shop bottom management; third, take full advantage of various quality tools to actively and efficiently improve tank shop processes, especially those processes which have serious influence to assembled product, frequently produce non-conformance products and seriously restrict whole tank efficiency improvement. After implementing above quality sustainableimprovement approach, tank shop achieves remarkable results in lowering poor quality cost, reducing non-conformance quantity and improving quality level.This paper is practical and has comprehensive instructive. After China's access to World Trade Organization (WTO), she will compete with many, many world-class manufacturers, quality is the best way to maintain customer faith, quality is the most powerful weapon against foreign competition, and quality is the only approach to maintain our growth and gain profit. Through the case of tank shop quality sustainable improvement, we can see quality improvement is no longer stayed on lips and quality improvement lies on every process, every aspect. Each employee at any moment can do a contribution to quality improvement.
