"In September 3rd, the gentleman did his work all day long, and he had no regrets when he was in the evening." This sentence can be used to describe Xi'an Cummins Engine's pursuit of quality. Since its establishment on December 16, 2005, Xikang has always been adhering to the development philosophy of “putting customers first and providing real value”. No matter whether it is R&D, quality or service, it is absolutely perfect.

Xi'an Cummins Quality Manager Wang Weina

As the most important part, the control of quality determines the quality of Xi'an Cummins' product quality. What is quality and what is the content of quality? For the ten years of work at Xi'an Cummins, Xi'an Cummins quality manager Wang Weina from quality to quality, the quality link has played every part of the work, but also let her really realize the quality The true value.

Customer First Provides True Value

“I started as a product and then changed to quality. After the work content changed, I truly understood what it means to put customers first and create value for them.” Wang Weina, who grew up with the company, feels that the company is Careful bit by bit, if the product is simply to meet the needs of users, then the quality let her experience for the sake of customers.

What is quality? Quality is actually the degree to which a product/service or feature meets its needs. The higher the degree of satisfaction of the demand, the better the quality. From this definition it is not difficult to see that quality is centered on customer expectations. For Wang Weina, her thinking has changed since she entered the quality field. From initially satisfying customer expectations, Wang Weina began to pay attention to and understand customer expectations, and communicated with all aspects of quality, and independently found out potential customer needs and guided customer expectations. This will affect the customer's habits and behavior. Of course, user feedback will also be used for quality improvement.

As a result, quality links from every aspect of the product. “Quality is everywhere, including the supplier's incoming quality management, operation quality, product quality, and even customer service quality,” Wang Weina said. Quality is not only reflected in the final product, but also reflected in every aspect of production. The more obvious.

Wang Weina said that the company will use the key issues identified in every key point. The pushback mechanism finds a final solution to avoid the recurrence of the problem.

At the same time, Xi'an Cummins will use the process stratification method to check the quality. “From management level to quality engineers and even employees, we all have a set of processes to regulate. Whether it is the inspection of the contents of our work or the management of equipment, we must be in place.” Wang Weina said that all the work will be cured In the process, every quality control in the production process is ensured through strict process management.

Xi'an Cummins also has a quality management system at the time of product release. According to Wang Weina, the engines will be put into storage after they are produced, and strict inspections will be conducted before they are put into storage, and certificates will be issued for qualified products. When it is necessary to export to the OEM, Xi'an Cummins will conduct secondary inspections to determine whether the storage environment will have a quality impact during the inventory. In particular, focus on the unchecked indicators in the final inspection to ensure the high quality of the manufactured products.
