The in-depth development of integration of defense and civilian technologies is an important way to realize the goal of enriching the country and strengthening the army. Encouraging and supporting private enterprises to participate in national defense construction, especially army construction (referred to as "civilian participation in the army") is an important content to promote the integration and development of national defense and civilian technology. In recent years, the participation of private enterprises, civilian technology and private capital in national defense construction has achieved remarkable results, which not only effectively guaranteed the smooth progress of national defense and military modernization, but also injected new strong impetus into the enterprise itself and local economic and social development. How can private enterprises gain a foothold in the field of national defense science and technology that they have never set foot in? Facing the characteristics of tight time, heavy tasks and strict requirements for supporting scientific research and production of military products, it is an inevitable choice and the only way for enterprises to join the army to strengthen product quality control and management and build the lifeline of product quality.

1. Raise awareness and establish a total quality management system for military standards.

Quality management and control is the "lifeline" of enterprises, and it has also been highly valued by enterprises in all walks of life and at all levels. However, in the process of participating in military scientific research and production, some enterprises also have some quality management misunderstandings, such as replacing military standard quality management with IS09000 quality management; Blind pursuit of profit and progress, ignoring product quality; The rectification of quality problems is not in place, and the same problems appear repeatedly; Quality management should be grasped and stopped. Only with military supporting tasks can we symbolically grasp quality management. In the final analysis, these problems and misunderstandings are due to insufficient understanding of enterprises and the failure to establish a total quality management system for military standards.

Military standard quality management system is divided into two parts: A and B. Part A is equivalent to the requirements of IS09000 series quality management system. Part B is the special requirements of military product quality management system, such as quality information, trial production of new products, test control, key processes, technical state management, etc. And in other general terms, the special requirements of military product quality management system have been added. The quality system of military standards is the key for private enterprises to enter the field of military scientific research and production. Units that have not passed the quality management system certification shall not undertake the task of developing, producing and maintaining weapons and equipment. However, enterprises can not simply copy military standards, but must refine them according to the characteristics of the industry, their own business and military products to enhance their operability.

Therefore, only by comprehensively and correctly understanding the quality management standards, closely combining with the actual situation of the factory, and in accordance with the requirements of the quality management standards, can enterprises finally establish a high-level total quality management system that conforms to the characteristics of enterprises and escort the military scientific research and production tasks.

2. Multi-point prevention and control, and establish a systematic product quality supervision and testing system.

In reality, enterprises at all levels know the importance of grasping product quality, and they have indeed made great efforts to grasp it. However, some enterprises have carried out quality rectification for many times, and the results are very satisfactory, and they are easy to fall into the quality management misunderstanding of "treating the headache and treating the foot pain". For example, some enterprises emphasize "escrow by punishment", that is, after the product quality has gone wrong, the parties and responsible persons of relevant responsible departments will be punished, hoping to make an example of them and play a deterrent role to avoid future accidents. Even some enterprises can't find the cause of the problem because it violates the basic principle of "traceability of quality information" in the quality management system.

The basis of traceability quality management is the collection and analysis of quality information. While establishing a total quality management system, enterprises must strengthen the performance testing, monitoring and recording of the whole product life cycle. From the inspection of raw materials to the process parameters of each process, from product performance testing to user feedback, one is to operate according to the requirements of quality manual and process specification, and the other is to strengthen process monitoring, testing and data collection.

Take the optical fiber inverter for low-light-level night vision as an example, it needs to go through nearly 20 processes and more than 200 technological processes before and after, and any slight defect in any link may lead to the unqualified performance of the final product. Aiming at the characteristics of long production process and complex influencing factors, a comprehensive and systematic process quality supervision and inspection system was established. In the production process control, the physical or chemical state changes of any product should be recorded in detail. Strictly carry out comprehensive inspection, including first article inspection, process self-inspection, next process inspection, department inspection, etc. To ensure that the process control is in place, fundamentally put an end to batch accidents, improve the stability and consistency of product performance, and provide the most original and authentic information for the traceability of product quality problems.

3. Scientific policy, establish a perfect strategy for continuous improvement of quality problems.

Many quality management technologies find ways and methods to improve product quality by analyzing, inspecting or evaluating finished products or semi-finished products, which is an "after-the-fact" remedy. The focus of quality management should be "preventive" pre-control and process control. Therefore, enterprises must carry out total quality management mode in quality management, strengthen quality awareness education, promote by leaders, involve all staff and be responsible for everyone, do a good job in quality management from the beginning, strengthen process monitoring, and keep the production process under control at all times. At the same time, for the quality problems found, we should adopt scientific and effective quality management techniques, correct mistakes and solve problems in time, and establish a long-term mechanism for continuous improvement.

3. 1 Double zero for quality problem

"Quality problems return to zero" is a major breakthrough and innovation in the history of aerospace quality management. Quality problem zeroing is a closed-loop management activity, which requires quality problems to be solved internally. It is a quality management method with China characteristics, which is constantly summarized, perfected and innovated by astronauts in practice, and gradually condensed into the requirements of "double zeroing and double five rules", that is, technology zeroing should be "accurate positioning, clear mechanism, recurring problems, effective measures, drawing inferences from others, and eliminating repeated failures", and management zeroing should be "clear process, clear responsibilities, implementation of measures, and seriously treat and improve" quality " It is necessary for "civilian army" enterprises to seriously study the connotation, significance and operation process of "double zeroing" of aerospace quality problems, and constantly improve the quality control level and standard in the actual scientific research and production of military crystals.

3.2 8D problem solving method

For some small and medium-sized enterprises that lack technicians and quality management personnel, the implementation of the "double zeroing" method for quality problems undoubtedly greatly increases the quality cost and cycle. In order to solve problems faster, these enterprises can try to control quality problems through the mechanism of 8D problem solving method. 8D problem solving method, also known as team-oriented problem solving method, provides a set of logical quick solutions for various problems such as product quality and production control, and builds a bridge between solving problems and improving quality. According to the product quality problems raised by users or found in production, the enterprise responds quickly and solves the quality problems in eight steps, namely, setting up a team, explaining the problems, implementing and verifying temporary measures, determining and verifying the root causes, selecting and verifying permanent corrective measures, preventing recurrence, summarizing and commending and forming an 8D report. According to this model, enterprises can control problems in the first time, reduce losses and impacts, quickly organize research and solve problems, and draw inferences from others to prevent the recurrence of problems, which not only saves quality costs, but also realizes continuous improvement of quality problems.

4. Strict standards, establish an effective product quality risk early warning mechanism.

The quality of military products is no small matter. With a high sense of responsibility and mission, the "People's Army" enterprises should ensure that the product quality is excellent and pass the performance test, formulate strict military test standards and scientific test methods, and "tolerate the army" for defects to ensure that every product and every performance index must undergo strict tests. It is necessary to adopt scientific means and statistical analysis methods, set up a red line and establish an effective early warning mechanism for product quality risks.

The product quality risk threshold needs to be set scientifically according to the actual situation of different enterprises and different products. In this process, AQL quality acceptance standards have been recognized and adopted by more and more enterprises. AQL standard is the average quality level of the worst process allowed when continuous batches are submitted for acceptance. According to different products and requirements, AQL can choose different sampling schemes. In AQL sampling, the number of samples is the same. The smaller the value after AQL, the fewer defects are allowed, indicating that the higher the quality requirements, the stricter the inspection. Once the product quality inspection fails to pass the AQL sampling inspection, it can be considered that a product quality accident has occurred. Timely warning of quality risks is issued to the person in charge of the enterprise, quality management personnel and technicians, and timely countermeasures are taken, which not only ensures the stability of military products, but also realizes the effective control of enterprise costs.

Military product quality management is endless. The vast number of "people's army" enterprises should keep in mind their mission, change their concepts, be brave in innovation, make full use of advanced quality management concepts and methods, scientific quality management technologies and means, constantly improve the scientific level of enterprise quality management, strictly control quality, build a "lifeline", successfully complete the supporting production tasks of military scientific research, and make new and greater contributions to national defense modernization.
