In early November 2011, the comprehensive statistical data of the four vehicle inspection lines of China National Heavy Truck Trucks' Share Quality Department showed that: In the first 10 months of 2011, the qualified index for measuring the total vehicle assembly, adjustment, and storage quality was once passed. The monthly average is over 93%. At the second node of the “second venture†at the end of the third quarter and the beginning of the fourth quarter, the passing rate of one-off inspection of trucks of China National SINOTRUK Truck Co., Ltd. was touched up to 100% and 95% several times. At the same time, this indicates that the initial quality of the off-line products of China National Heavy Truck Trucks truck heavy truck has gradually approached and reached the advanced level of 100% qualified for international heavy truck companies.
It is reported that since the start of the “second venture†project in the second half of 2011, the decision-making layer of Sinotruck Truck Co., Ltd. has started to launch the lean benchmarking project for the TS16949 quality system, and through the introduction of the quality standards of the German MAN company Optimize the inspection process of the entire vehicle and gradually promote the steady and substantial improvement of the passing rate of one inspection.
Scientific inspection, adopting international requirements and new quality certification standards
In accordance with China National Heavy Duty Truck's requirement for “Second Venture†and the need for maximum profit for China's customers, China Truck Group carefully analyzed and refined internationalization requirements and new quality certification standards to identify the reliability of the steering system. The seven major items such as the clutch, shifting system inspection, and three-legged sealing inspection of the vehicle have become the main inspection targets for the special inspection items of the vehicle, and have become a scientific and effective tool for greatly improving the passing rate of one-time inspection.
In accordance with the main inspection priorities for improving the quality of trucks entering the warehouse, China National Heavy Truck Truck Group Co., Ltd.'s quality inspection department has carefully organized and organized a new vehicle inspection and inspection management system based on the objective of strengthening scientific and orderly management, combining new job content characteristics. The relevant documents for the inspection methods and vehicle inspection procedures are issued to the hands of each quality inspector so that the quality inspectors are familiar with the inspection process, are familiar with the inspection standards, and have strict inspection procedures, and perform 100% inspection on each vehicle component.
On the basis of doing a special inspection, we will consolidate and summarize all the contents of the high-frequency quality improvement space, and set this type of content as a floating inspection item, requiring every inspector to pay close attention to the quality inspection process and find it in a timely manner. Never miss a quality inspection link.
Implement responsibilities and implement a careful quality feedback mechanism
China National Heavy Truck Truck Group believes that as the market competition becomes more and more intensified, the quality requirements for the inspection of completed vehicles will gradually move closer to the level of internationalization, and the mass quality requirements must be highly valued. It is necessary to deeply understand the quality of the entire vehicle. The significant impact of quality.
In accordance with this line of thinking, Sinotruk Truck Co., Ltd. has formulated a detailed information feedback mechanism. During the inspection process, quality inspectors found that batch quality requirements were to be resolved, and they were reported to the department in a timely manner. The department reported the relevant personnel step by step according to management authority, conducted careful analysis, researched and solved solutions; according to the new solution, the information was fed back to the assembly line in a timely manner. Or related departments.
At the same time, in order to ensure the normal delivery of vehicles, the work of quality control measures has also been stepped up. All relevant departments and teams fully exerted the role of the pre-class meeting, conducted a summary analysis of the problems found during the inspection process on the day, and notified the employees at the next class meeting to make sure that the employees knew what was going on.
In the process of the lean benchmarking project, Sinotruk Trucks deeply understands that the vehicle assessment is the final gateway for vehicle quality inspection. The key and importance of its position can be imagined. After in-depth and prudent research, the specially selected senior quality management experts took on this important key responsibility and conducted on-site gate guidance. Experts know that: the quality of quality supervision and the quality of the vehicle's assessment personnel directly affect the quality of the vehicle, thus affecting the company's quality reputation. Based on this, they regularly carry out training on skills and quality improvement training, and strive to improve the skills of quality inspectors.
Practice-oriented, in-depth promotion of professional knowledge and quality responsibility incentive system
With the ever-changing product technology, the monitoring level is increasingly demanding, and the quality requirements of quality inspection personnel are more stringent. In order to keep up with the pace of development, quality control of the entire vehicle is performed, and senior quality management experts take time during production. "Theory + practice" training method, organizers to focus on learning the new product structure, performance and working principle, with the technical staff for the opposite exchange, a comprehensive and systematic grasp of relevant operating skills.
In training and inspection, they found that: Monitoring the level of the plate chain inspection work is a key step in the process of quality inspection to improve the quality level. After timely communication with the relevant responsible persons to coordinate and effectively improve The scientific level of quality control. After the combination of theoretical and practical training, the quality of your quality supervision and the entire vehicle assessment staff has greatly improved.
On the basis of striving to improve the overall professional quality of the vehicle's assessors, China National Heavy Truck Trucks' Share Quality Department has also implemented a quality responsibility incentive system. In view of the nature of the work of improving the passing rate of one-off inspection of the entire vehicle, the quality department gradually decomposes the quality responsibility target undertaken by the company into two assembly departments and quality systems of professional plants, and strives to achieve a pass rate for one-off inspection of the entire vehicle. At the same time, every unit must assume responsibility, and everyone should have indicators on their shoulders, and they should also make sure that those who work attentively do not suffer losses, and that employees' professional knowledge can be used.
In October 2011, the two assembly departments of China National SINOTRUK Truck Co., Ltd. launched a fierce competition in terms of the increase in the passing rate of one-off vehicle inspections.
