Li Yonghua, Ni Changqing (Jinxī Natural Gas Chemical Co., Ltd., Huludao, Liaoning, 125001). Abstract: By introducing some of the more advanced management theories available internationally, this paper compares the current state of quality management in Jintianhua’s urea production, identifies the related problems, analyzes the main causes of these quality issues, and proposes measures to address them, offering strategies for improving the quality management of Jintianhua’s urea. A comprehensive solution for quality management is proposed, starting with strategic quality management, moving on to strengthening organizational structure, raising quality awareness, ensuring full employee participation, and using the PDCA cycle as a tool for quality assurance. The organizational recommendations emphasized the importance of teams, and for the first time proposed organizing teams based on micro-molecular type characteristics. It is necessary to use the PDCA cycle to continuously strive for self-improvement in quality, and to employ these methods to advance quality management over time, thereby providing guidance for the company’s quality management efforts. It is hoped that this will contribute significantly to the company’s quality management practices. Keywords: urea, quality management, research. 1 Introduction: This paper focuses on the quality management issues of urea, the main product of Jintianhua Company. Jintianhua Company is a large state-owned enterprise. Its plants for producing 300,000 tons of synthetic ammonia and 520,000 tons of urea were put into operation in 1993; plants for producing 60,000 tons of methanol and 15,000 tons of dimethyl carbonate were built in 2004. Its main product is urea. As the company has grown, its approach to quality management of urea has evolved from low attention during the seller’s market era to high attention in today’s buyer’s market era. From being initially rejected by the market to gaining high recognition today, and becoming one of the **first batch of products exempt from inspection in 2001, its quality management has evolved from weak to strong. The company’s latest quality manual states that customer satisfaction is our eternal pursuit. This is a return to an understanding of quality. This article summarizes the early problems in urea product quality management as well as the successful experiences gained later on, drawing some useful conclusions that can serve as a guide for improving the quality of other products manufactured by the company. Through an analysis of the history and current situation of a large urea production enterprise, the prominent issues in the quality management of its main product – urea – were identified and summarized. An analysis was conducted from various aspects such as employee awareness, quality strategy, execution capability, quality training, and quality costs, in order to pinpoint the root causes of these problems. After the cause is clearly analyzed, the methods for solving the problem are discussed. For the convenience of studying the issue, relevant theories were also reviewed earlier. By using empirical research and before-and-after comparison methods, and starting with an analysis of the history and current status of urea product quality, the problems are identified, their causes are analyzed, and a set of solutions to improve product quality is developed. 2 Introduction to Quality Management Theories 2.1 Deming’s Quality Management Theory Dr. Deming developed new sampling methods and demonstrated that statistical techniques are also useful in business. The Japanese business community holds Dr. Deming in high esteem, calling him the father of quality management in Japan. Deming was a pioneer of Statistical Quality Control (SQC). Deming’s main contributions are the aforementioned “Deming 14 Points” and his PDCA cycle management method, also known as the “Deming Cycle”. It is evident that Dai is truly a master of quality management. 2.2 Dr. Juran’s Quality Improvement Theory: The quality management concepts and methods advocated by Dr. Juran have continued to influence the world as well as the development of quality management on a global scale. His \"Quality Planning, Quality Control, and Quality Improvement\" is known as the \"Juran Trilogy\" or the \"Trinity of Quality.\" He made outstanding contributions to laying the theoretical foundation and basic methods for Total Quality Management (TQM). He introduced the concept of the quality loop (also known as the quality spiral). He also proposed the “80/20 principle” and put forward a concept of quality of life. He was the first quality management expert to propose the calculation of quality costs. He suggested that if unfavorable costs can be reduced, the company’s profits can increase. He was the first person to introduce the concept of quality cost. 2.3 Feigenbaum’s Theory of Defect Costs Feigenbaum played a key role in promoting the \"defect cost\" approach and was a pioneer in total quality management. He realized that quality is not merely a collection of tools and technologies, but rather an integration of all aspects and processes. He also noted that when the quality of one process in a company improves, the quality of other processes as well improves. He advocates a team spirit of cooperation among departments. He published the book \"Total Quality Control\" in 1961. According to Feigenbaum, quality should be defined by the user. He was the first person to propose the concept of total quality control. 2.4 Other related theories In the theories of quality management, there is also Crosby’s “zero defects” theory. Crosby’s philosophy: “Prevention is better than cure.” Based on the concept of “zero defects,” Crosby believed that no quality defects should exist. Crosby’s major contribution to quality lies in his conceptual insights. In the book “Quality Is Free,” Crosby proposed a famous slogan: “Do it right the first time,” which is his most well-known idea. Japan has also produced a master of quality management, and his name is Kaoru Ishikawa. His cause-and-effect diagrams (also known as fishbone diagrams) for solving problems and implementing quality cycles, including quality improvement efforts, later known as Ishikawa diagrams, represent Ishikawa Kaoru’s major contribution. He regards external customers as an object within the quality cycle. He actively advocates that company leaders must possess considerable vision. The theories of these masters all have their own advantages; they played a significant role in the 20th century and are still being used to this day. But China lags far behind in quality management. The same is true for Jintianhua; we should catch up. 3 Quality management issues and cause analysis of Jintianhua urea 3.1 Problems existing in the quality management of Jintianhua urea First, the scope of quality coverage is incomplete. When it comes to quality, what people usually think of first is the internal quality of tangible products. For products such as urea, as long as the internal parameters are within limits, most people consider the quality to be fine. But people often overlook the quality of packaging ； Another positioning error is service quality. In the process of selling fertilizers, although most of them are sold to agricultural supply companies – where the volume of fertilizer is large but the number of customers is small – a small portion is sold directly to farmers, who constitute a large customer base. Because the factory does not include these in its quality management processes; in the factory’s view, once the products leave the factory, it is the responsibility of the merchants and users. Second, the requirements for meeting quality standards are relatively low. For agricultural urea, there are three grades: premium grade, first-grade, and qualified grade. Although all of them can be used, their performance varies. It is relatively easy to produce high-quality products from bulk fertilizers, yet no one emphasizes this point. Before becoming **inspection-exempt products in 2001, urea was shipped as standard-quality product, as the factories believed that in the market, higher quality did not necessarily mean a higher price ； Lower standards at the time of production can minimize the number of defective products ； This also meets the **standards ； Users generally agree as well. These views are undoubtedly short-sighted. Companies focus on short-term gains and losses; producing products to meet standard requirements rather than customer needs is a short-sighted approach. Third, quality management holds a low position in enterprise management. At the beginning of the factory’s operation, management focused primarily on ensuring stable operations and had no time to address quality control. At that time, quality control was limited to identifying defective products produced, with no corrective actions taken, let alone any preventive measures. Early urea quality management was a closed-loop system, that is, management without feedback. Quality management refers to the quality control within a production system; it focuses on the product quality during the production process and falls under the category of final inspection. At this point, it is not possible to coordinate the operations of various workshops and departments from a quality management perspective. There are no quality policies or objectives, the organizational structure is weak, and management responsibilities are concentrated on the supervisory functions of the Quality Control Department. Fourth, the quality control measures have deficiencies. A closed-loop system has been established in management; corrective actions are increasing, but preventive actions are fewer, with the amount of defective products dropping to around 2,000 tons per year. The true meaning of quality management still hasn’t been understood; there has been insufficient shift toward preventive measures, and problems have not been resolved through technical solutions. For example, the problem of powder formation in scattered warehouses ； Problems with rotary screen sifters and vibrating screen sifters ； Issues such as the air vents in the granulation tower. 3.2 Cause Analysis 3.2.1 Lack of a correct quality mindset: There is no customer-first philosophy among leaders, let alone among ordinary employees. When the market is sluggish, companies with better quality are less affected, whereas our factory has suffered significant impacts; the reason for this is the lack of a proper quality mindset. The issue of leadership’s view on quality should be emphasized here in particular. “The “14 Principles of Deming” explicitly emphasize the importance of leadership in quality management; Dr. Juran’s 80/20 principle also indicates that 80% of the responsibility for quality lies with leadership, and Crosby further stressed the importance of leadership in quality management. Focusing on customers is the key aspect of all quality management theories, and it is also a fundamental requirement specified in quality awards and ISO standards. The ISO9000:2000 version further makes “customer focus” the first principle. It is evident that customer satisfaction is the core philosophy of a company, an ever-relevant concept of quality. 3.2.2. Lack of strategic quality management: A quality management strategy refers to the approach in which, throughout all operational and capital management activities, a company must put people first and focus on improving quality and efficiency. All of the company’s activities should be centered around quality-related actions, with quality management and control being elevated to a strategic level. Strategic management consists of three parts: strategic analysis, strategic choice, and strategic implementation. Put simply, strategy is about an organization’s long-term direction of development. It should align resources with the changing environment, especially the market, consumers, or customers. The Jintianhua Quality Manual states: continuous innovation, pursuit of perfection, leadership in the industry, and customer satisfaction. The introduction of these strategies and concepts undoubtedly provides a direction for businesses. Its own goals for quality management were also set. A strategy must be formulated and implemented in order to be effective. Jintianhua has a quality strategy in place, but no detailed implementation plan has been developed. 3.2.3 Poor implementation of quality management Another reason for quality management issues is the poor implementation of quality management practices. The system is not perfect, but there are quality management systems in place. But if the higher levels do not pay attention to quality work, then there is no need to talk about it at the lower levels. It seems that everyone believes that detecting defective products only brings losses to companies, which leads middle managers to relax the standards. The reason lies in the issue of execution ability. Although certification has enhanced employees’ quality awareness, the number of defective products remains high. These results indicate that process improvement efforts are inadequate, with many tasks failing to form a closed loop. And this is in contradiction to the requirements of ISO9000. The company did not follow this, or rather, it did not implement it immediately. Execution capability is what brings competitiveness; success stems from it. A lack of execution capability is one of the reasons for Jintianhua’s quality management problems or shortcomings. 3.2.4 Insufficient training in quality management. Here we quote a famous saying by the Japanese master of quality management, Kaoru Ishikawa: “Quality control begins with education and ends with education.” ”The inadequate education in quality management at Jintianhua is evident in several aspects: first, there is insufficient instillation of a quality mindset. It can be said that senior and middle managers still possess a certain level of quality awareness. Meanwhile, the quality awareness among frontline employees is relatively low. Because there is basically no systematic quality training arranged at this level. Second, there is insufficient training on management methods. There are many quality management methods, such as statistical techniques, fishbone diagrams, Pareto charts, and so on. These techniques are very simple, but highly effective. Third, there is no stable training plan. Although the certification documents and improvement measures are in place, a comprehensive training plan is lacking; the role of such a plan in management work is well known to all. The first function of management is planning. 3.2.5. Insufficient awareness of quality costs: The poor implementation of quality management in enterprises is largely due to a lack of understanding regarding quality costs. Jintianhua is no exception. Because the company has never conducted any statistics on quality costs. Representing quality costs in Figure 3.9 makes the point clearer. The total of internal failure costs and external failure costs is referred to as failure costs; moreover, the loss in value resulting from poor quality that leads to lower prices for the goods to be sold should also be counted as internal failure costs. The impact on a company’s product reputation is even greater, more lasting, and immeasurable. Identification costs are usually essential, while prevention costs are more often included in other cost categories. Failure costs represent a concept of marginal cost – that is, the reduced revenue and increased expenses resulting from a failure as compared to when no failure occurs. Without these failures, these costs would have turned into increased profits. Research shows that a small increase in the prevention costs of a process leads to a significant reduction in the costs associated with failures, an amount that far exceeds the increase in prevention costs. However, at present, few people at Jintianhua are aware of this. Jintianhua Group classifies all quality costs as manufacturing costs or administrative expenses; it does not keep separate records of them nor conduct any corresponding cost analysis. This is an area where quality management needs improvement. 4 Strategies to Improve the Quality Management of Jintianhua’s Urea 4.1 Formulating a strategic plan To enhance the quality management at Jintianhua, it is necessary to first elevate it to a strategic level. It must be clear that throughout the entire production and operation process, a people-oriented approach should be adopted, with improving quality and efficiency as the focus; all activities must revolve around quality. The strategic management of quality refers to a quality that is not limited to product quality alone, but rather to a comprehensive and all-round quality; the goal is to elevate quality to the status of a core competitive advantage. A modern enterprise management system is a multi-objective system, but its core issue is quality; since enterprises aim to make profits, they must occupy the market with their products. To do so, they need to win over customers, and to win over customers, they must provide high-quality products. Only by strictly ensuring the quality at every stage of the enterprise can product quality and service quality be improved. The goal of quality management should not be limited to product quality in a narrow sense; it must aim at quality in a broader sense. Quality competition is an important form of non-price competition; it offers more competitive advantages and constitutes a core competitive strength. Jintianhua should formulate a quality management strategic plan. A comparison between strategic quality management and traditional quality management is shown in Table 3. Table 3 Comparison between Strategic Quality Management and Traditional Quality Management Traditional Quality Management Strategic Quality Management Focus Improving product and service quality Emphasizing education, changing attitudes, fostering a sense of quality ethics among all employees, building a quality culture, and enhancing the company’s quality image. Technical management emphasizes the conformity of internal and external quality characteristics of products, stressing the unity of these two types of quality. It pays attention to cultural quality and aesthetics, as well as value creation through inherent qualities. The focus of management lies on the quality of products, the quality of production processes, and the quality of work; it is people-centered, and through management and motivation, it encourages people to consciously ensure and improve quality. The key aspects of management include the quality of products and services themselves, as well as their economic and efficiency aspects. In terms of methods, maintenance inspections and controls are used to gradually improve quality and achieve breakthroughs. Marketing and customer satisfaction are also important; starting from marketing strategies and focusing on intangible assets such as brand image, with customer satisfaction as the goal, comprehensive quality marketing is carried out. At present, urea products have entered a mature stage in the market, and soon they will enter a decline phase. The competitive environment is not very favorable for companies, so they should prepare in advance. For example, the slow-release urea developed by companies these days is an illustration. That is, it is necessary to win a changing market with changing quality, and such changing quality should even include changes in physical properties. Efforts should be made to develop downstream products of urea, including conventional slow-release urea, large-grain urea, large-grain slow-release urea, urea-based coated urea, compound fertilizers, BB fertilizers, and others. Achieving differentiation through functional transformation is also an important means of quality competition. 4.2 Strengthen organizational development – The \"departmental silos\" represent the biggest obstacle to implementing quality management. Deming proposed: fostering collaborative efforts among groups, teams, and employees ； Juran also put forward a similar view: the company’s management systems and business processes should be improved every year to maintain momentum in process improvement. The real reason for improving the organizational structure is that the organization must be able to respond quickly to customer needs. To meet the requirements of quality management, organizations must make changes. The author is fairly in agreement with the “customer chain” approach. Organize customers of suppliers; the customers are merely the organization’s customers. However, the concept of customers can be extended within an organization as well; that is, those in the downstream position are the customers of those in the upstream position, thus forming a complete customer chain. Based on this concept, it helps to change people’s perception of organizational structure; employees are not only accountable to their supervisors but also to the customers at the lower levels, which is very useful for quality management. It is also a very good practice to organize a team. The members of this cross-functional team are made up of people from various departments, who work together to accomplish tasks that none of them could handle on their own. A good example of well-organized structure in the microscopic world is the benzene molecule. A benzene molecule consists of six carbon atoms and six hydrogen atoms; the six carbon atoms form a regular hexagonal structure. Due to the tension in the ring, such a molecule should be unstable, yet it forms a structure that is recognized as stable. The six carbon atoms are first bonded together by σ bonds; the bonding electrons are shared only between adjacent atoms, thereby creating a binding force (electron sharing). Meanwhile, adjacent carbon atoms are also bonded by π bonds, which generates another force. It was later discovered that the electrons responsible for forming the π bond do not belong solely to the adjacent carbon atoms; rather, they are shared among all six carbon atoms. In other words, six electrons form a large π bond across the six carbon atoms, and this large π bond binds the six carbon atoms together tightly. If any external molecule reacts with it, it makes no difference which atom it encounters; the outcome is the same, as the six carbon atoms are symmetric. Table 2 can illustrate the relationship between benzene molecules and tissues. Table 2: Comparison table between the benzene molecule and an excellent organization. The benzene molecule and an excellent organization are both composed of carbon and hydrogen atoms; the σ bonds between these atoms are tightly connected, allowing them to work together effectively. There is a strong sense of teamwork, as well as large π bonds that facilitate collaboration among various team members. In terms of external relations, it’s not possible to identify which individual atom is responsible for what – everyone works together for the benefit of customers, with no distinction between individuals. An organization that possesses the characteristics outlined in the table above can be referred to as a “benzene ring” organization. 4.3 Raise quality awareness. First, senior management must develop a sense of crisis regarding quality. Quality is the key to a company’s success; it is the cornerstone of corporate achievement. Quality reflects a company’s core competitive capabilities, and without quality, nothing else can exist. When it comes to quality, one should assume that the market might soon go into a downturn. Only in this way can quality be properly managed and product updates ensured. Deming pointed out that senior managers must take on management responsibilities in both words and actions, emphasizing that first and foremost, they need to have a quality-first mindset ； Second, all employees should have a quality-first mindset. This should start at the top level, driving the middle management and guiding the grassroots level. It is required that a company’s products, services, management, and personnel all meet the standard of putting quality first. From procurement to marketing, from human resources to financial management, the principle of quality first must be upheld. Only in this way can enterprises carry out high-quality work, produce high-quality products, develop high-quality projects, and achieve high returns. Third, adhere to the principle of “getting it right the first time.” Crosby believes that getting it right the first time is often cheaper and can save a significant amount in quality costs. Crosby says in his book \"Quality Is Free\": \"If we think carefully and commit to getting it right the first time, we will take a big step forward, eliminating the waste caused by defective products, rework, and repairs, avoiding increased costs and a reduction in opportunities for personal development.\" ”In other words, as long as it’s done right the first time, it’s better to incur extra costs than to have to redo it. Fourth, a good quality is ensured by the process, rather than through quality assurance based on inspection. Deming believed that inspection is intended to improve processes and reduce costs, and nothing else. Therefore, companies should actively promote process improvement to reduce factors of variation and ensure quality through streamlined processes. Jintianhua has an example in this regard. It turns out that the levels of urea biuret often exceed the specified limits. One of the reasons for this is the addition of urea from the reflux tank to the system. Since this portion of urea stays in the tank for a relatively long time, sometimes up to several days, its content of biuret is high; therefore, if an slightly larger amount of it is added, it can cause the biuret level in the product to exceed the allowed limits. The valve that controls the amount of urea added is a 4-inch valve, and even the slightest movement causes an excess amount to be added. At first, people simply responded with the phrase “improve operations,” but the problem remained unsolved. By 2003, the problem was resolved after changing the control valve to 2 inches. In fact, process improvement is a form of source control; after such improvements, quality can be determined through process control and assessment. In 2003, through such process improvements, the amount of substandard urea in 2004 was reduced by more than 1,000 tons compared to previous years. Excellent quality stems from superior design, as well as easy-to-implement processes and management systems. 4.4 Employee Participation and Incentives Jintianhua has 1,836 employees in total, of whom 557 are professional and technical personnel, accounting for 31% of the total workforce. There are 8 employees who receive ***** allowances, 7 professors-level senior engineers, 118 employees with senior professional titles, and 197 employees with intermediate professional titles. Over the past ten years since its commissioning, Jintianhua has obtained 17 scientific and technological achievements at the municipal level or above, and carried out more than 50 major technical upgrades to its installed equipment. How to enable these people to play their proper role and how to leverage the company’s technical advantages is a major issue. In 2003, the company established a quality improvement team; its members came from various relevant departments, including those in design, the workshop, logistics, and technology. After these teams were established, quality control procedures for product quality were developed and implemented in 2004; within less than half a year, the problems were resolved. For example, the issue of particle size is resolved by screening the urea with the worst particle size ； The problem with biuret is addressed by controlling the amount of urea solution added to the storage tank, as well as by regulating the residence time and temperature of the normal urea solution. The task force worked continuously and came up with 12 solutions, which played a positive role in improving the quality in later stages. In 2004, the company introduced a quality incentive program that included five units; as a result, the amount of defective products in that year decreased by more than 1,000 tons, a reduction of 40%. A comparison of the number of defective products before and after the problem-solving efforts is shown in Table 4. Table 4: Number of defective products from 2001 to 2004, in tons. Category, Year, Particle size, Moisture, Biuret, Others, Total. Defective product rate, %: 2001: 566, 150, 116, 534, 522; 60.389%. 2002: 209, 012, 059, 602, 806; 60.474%. 2003: 203, 815, 932, 253, 250; 60.472%. 2004: 877, 021, 301, 198; 0.224%. Quality management relies heavily on the participation of employees, on the involvement of everyone. Motivating employees is an even more important aspect. When a leader lets their subordinate take charge of guiding others in carrying out a task, that subordinate performs better than when the leader does the work themselves, especially when the leader tells the subordinate, \"You can definitely do this well.\" This shows that people all have initiative; it just depends on whether they have such opportunities. Timely encouragement is very important for consolidating achievements. After the project was completed, the company rewarded it and promptly introduced a quality award program to reinforce these measures. 4.5 Upgrading quality management through the PDCA cycle: The implementation of the PDCA cycle for quality management in Jintianhua’s urea production is as follows: 1. Develop a detailed plan. Based on the current management situation of Jintianhua, relevant management systems need to be improved. Secondly, the existing quality issues should be analyzed, the main causes identified using appropriate tools, and corrective action plans formulated. A long-term plan for Jintianhua’s quality management should also be developed, such as a brand strategy or a leadership strategy. Jintianhua’s urea products are at an advanced level in the industry, but urea is after all a conventional fertilizer. It is necessary to investigate farmers’ needs and, based on those insights as well as the company’s own capabilities, continue to improve the existing slow-release urea products, add more functional features to them, and advance the development of compound fertilizers, so as to be well prepared for the decline of the urea market. 2. Formulate specific countermeasures and organize their implementation. Quality improvement is a major issue for the entire company; various task forces or teams are organized to address specific quality problems. It also mobilizes all employees to identify problems in quality management on their own and carry out self-improvement. Turn quality improvement into a conscious action by all employees. Attention to the use of quality management tools is something that must be strongly emphasized in quality management. For example, causal diagrams are used to categorize causes into six aspects: people, equipment, materials, processes, environment, and measurement methods (5M1E). In fact, for more complex problems, using tools such as cause-and-effect diagrams is an excellent choice, as it helps to solve them. Implement quality management in conjunction with the company’s 6S activities. Generally speaking, 5S management is often mentioned, which refers to sorting, organizing, cleaning, standardizing, and discipline; Jintianhua adds safety to it, resulting in 6S. The goal is the same – to strengthen management. This management method, which originated in Japan, is also a way for Japan to improve quality control, and it has since been widely adopted by businesses today. It is primarily based on the idea that \"carelessness is the biggest obstacle to quality control.\" This on-site management method is particularly suitable for Chinese companies, as many of our enterprises are reluctant to handle such minor tasks. In terms of quality management, sorting can be understood as a comprehensive organization of existing awareness, rules, and methods; standardizing refers to the thorough establishment of the rules and methods that will be used; cleaning involves the purification of the environment and processes in order to ensure high quality; maintaining order means upholding these practices; and discipline refers to the principle-based approach employees follow in their work, an excellent habit that can be considered as quality discipline. 6S management can enhance a company’s image, boost employees’ sense of belonging, improve efficiency, ensure safety, and guarantee quality; it is a tool that addresses both internal and external aspects. Its essence is to emphasize small things, encouraging employees to work methodically (by following rules and standards) and to develop good habits. These are undoubtedly essential for quality management. 3. Conduct follow-up inspections to make timely corrections. The implementation process is complex, with many unexpected situations, which requires a supervision mechanism, especially from leadership. It is essential to eliminate obstacles along the way, conduct evaluations of progress at regular intervals, and strengthen quality assessment to ensure that the plan moves forward on the right track. 4. Summarize improvements and move on to the next cycle. To implement quality improvements, after each phase is completed, it is necessary to carefully summarize the experiences and lessons learned and document them so that everyone can learn from them. This is also a wealth for a company; unique management methods should be considered intangible assets of the company. In this way, it is possible to move on to the next goal and initiate a second PDCA cycle; by repeating this process, quality management will gradually reach a new level without anyone even realizing it. 5 Conclusion: Quality is the key term in today’s world of goods; it is an issue of widespread concern among the public, and it serves as a powerful tool for companies to gain a competitive advantage. Without quality, there is nothing. The past problems or current shortcomings in the urea quality management at Jintianhua Company mainly include a low priority given to quality tasks, poor quality awareness among employees, inadequate operation of the quality control system, and a lack of understanding regarding quality costs. The correct approach is to use quality management to guide all aspects of a company’s operations, advocating that quality is the core advantage of an enterprise; it determines the survival and development of the company as well as its future. To improve quality management, one should start from the following aspects. Firstly, there must be a strategic focus on quality, as well as a philosophy of developing the enterprise through quality. Organizationally, there must be work teams suited to the requirements, with an emphasis on both horizontal and vertical collaboration, in order to build a team with high-quality capabilities. Attention should also be paid to maintaining connections with internal and external customers, in order to improve the speed of response to their needs. In terms of quality awareness, it is necessary to have an understanding of total quality management; one should not focus solely on product quality. It is important to realize that only a high-quality team can produce high-quality work, which in turn leads to high-quality products ； There must also be a customer-first mindset: when a company puts the customers first, the customers will surely reward the company. If a company provides high-quality products to its customers, those customers will in turn give the company exceptional returns. In terms of employee participation and motivation, it is necessary to trust in their capabilities, significantly increase their level of involvement in management, help them find their place at work, and truly provide them with a \"space for expressing their individuality and realizing their value.\" In practical operations, the PDCA cycle method is vigorously implemented, and various tools for quality management are actively utilized – the so-called \"tools are necessary for one to do his work well.\" By adhering to the philosophy of putting customers first and the goal of serving society, Jintianhua’s urea quality management will continue to improve, and the goals of \"customer satisfaction and mutual success through integrity\" will be truly achieved.

Quality is a constant theme for enterprises -------- A brief discussion on the quality foundation for achieving \"inspection-free\" status Hu Jiquan (Sinopec Hubei Fertilizer Branch, Zhijiang, Hubei, 443200) Hubei Fertilizer is a large-scale enterprise; since its operation began in 1978, as of May 31, 2006, it had produced a total of 11.3476 million tons of \"Yangtze River\" brand urea. The rate of high-quality products, as determined by annual sampling inspections conducted by the provincial technical supervision bureau, was 100%, while the company’s own inspection results showed a pass rate of ≥98%. The rate of first-class products was 100%. Urea products are sold in 51 cities and counties within the province, as well as in 12 regions outside the province. The long-term stability of product quality has made a significant contribution to agriculture in Hubei, leading to increased agricultural production and higher incomes for farmers. Enterprises have made sacrifices for the sake of interests and the well-being of the people, and now they achieve modest profits. At the same time, our \"Changjiang\" brand of urea has captured over 80% of the market share in the province. In the rural areas of Hubei, there is a widespread saying among towns and villages that \"Changjiang brand urea is the best choice no matter when it’s used\", which has helped to create a strong brand reputation. In 1990, the urea product won a **Silver Award**, and it went on to receive the Provincial Famous Brand Award for four consecutive sessions. It was also recognized as a \"Famous Trademark\" by the Provincial Administration for Industry and Commerce for five consecutive sessions. During the process of total quality management, Hubei Fertilizer Branch took the following actions to enable its urea products to receive **exemption from inspection**. 1 A suitable and effective quality management system was established. In 1983, Hubei Fertilizer began to implement total quality management, and by 2005 it started the certification process for the ISO9001 quality management system. Our main approaches were: 1) Ensuring two things, namely organizational readiness and the availability of qualified personnel. A Total Quality Management committee was established, along with a quality leadership team headed by the plant director (manager) and composed of heads of various grassroots administrative units as team leaders. The main workshops (teams) are equipped with part-time quality inspectors, while the company has a Quality Supervision and Management Office, as well as a Standardization Office, an ISO9001 Leadership Team, and a Quality Inspection Center. There are 139 full-time quality inspectors and 24 registered quality engineers, ensuring that quality management covers every team and position; this creates an effective three-level quality management network from top to bottom. For ISO9000 personnel training, we adopted a step-by-step approach, progressing from basic requirements to those related to obtaining certification. We printed over 500 sets of training materials and organized 12 training sessions at various levels to help staff comply with the standards. Four external registered auditors were trained, and 24 internal quality auditors were trained as well. 2) We place great emphasis on the establishment of quality management system documents. In addition to the quality manual, procedure documents, and work instructions, we have also developed over 1,950 management standards, work standards, and technical standards, covering all aspects of quality management. The company always focuses on customer needs, introducing an advanced model for excellence in performance management into its daily operations. It has established seven management principles required for quality awards, covering leadership, strategy, customers and the market, resources, process management, measurement, analysis and improvement, as well as business results. By combining these principles with the realities of the production site, the company has developed sub-systems for ensuring effective management in areas such as on-site management, process technology management, HSE safety, environmental protection, and employee morale management. This approach enables comprehensive management that ensures vertical alignment and horizontal coordination within the performance management framework. 3) Efforts are underway to establish a comprehensive quality management system that takes the ISO9001 quality management system as its core, integrating HSE (Health, Safety, and Environment management system), ERP, and internal control systems. The integrated management system unifies the requirements of various standards under one management framework, adopting the principles of common compatibility and complementary specificity. This approach enables resource sharing while ensuring the suitability, unity, order, and effectiveness of the management system, thereby improving the company’s product quality and facilitating development through the PDCA cycle, self-improvement, and continuous enhancement. 2. Strengthen total quality management by integrating responsibilities, powers, and interests. The quality policy of our Hubei Fertilizer Branch is to enhance total quality management, ensure that quality is integrated into all aspects of work, and provide customers with high-quality products and top-notch services. The company establishes the quality objectives of the organization in line with its overall policy, and the departments related to quality further break down these objectives based on that overall policy. Following the principle of functional attributes, they set specific objectives at the grassroots level in terms of people, machinery, materials, methods, and the environment, ensuring that responsibilities are assigned to individual persons across all levels and areas. The achievement of objectives is governed by the process control of the quality system, key processes in the manufacturing workflow, critical control points, and the assessment of positions requiring special attention; the measures set at the higher level serve as the objectives for the lower level. The company strictly adheres to the ISO9001 international standard by auditing its quality system, quality objectives, and product quality. It takes timely action to address any non-conformities, and evaluates issues in accordance with the quality reward and punishment regulations. It organizes monthly PDCA management cycles, implements effective measures promptly, defines responsibilities and sets quantitative targets, ensuring that everyone has clear duties and that all tasks are carried out according to established standards. This approach ensures that product quality is under control throughout the entire process, helping to achieve the set goals. In quality management, the company requires that quality managers shift their focus from management tasks to providing services at the grassroots level. Management should extend from a horizontal to a vertical approach, reaching deep into the production sites, with strict adherence to the \"2, 4, 4\" principle. That is, “two emphases”: emphasizing excellent product quality ； Emphasize strict product standards ； “The principle of “four no-lets-go”: no let-go until the quality issues are thoroughly investigated, no let-go until responsibilities are clearly defined, no let-go until corrective measures are implemented, and no let-go until those responsible learn from their mistakes ； “The four principles of obedience: output obeys quality, the workshop obeys quality inspection, physical products obey standards, and the company obeys customers. Any quality issues that arise due to failure to follow the requirements must have those responsible held accountable, and a quality veto power shall be implemented. Our management philosophy is: prevention first, process control, measurement and inspection, and continuous improvement. Our guarantee approach is: raising awareness, clarifying responsibilities, quantifying assessments, and linking performance. Our control methods include: statistical process control techniques, common statistical techniques, sampling inspection, point estimation, interval estimation, and hypothesis testing. 3 Establish a corporate quality culture and enhance quality awareness. Quality education is a key aspect of implementing total quality management. In recent years, companies have invested over 500,000 yuan in quality education programs; in 2006, additional funds were allocated for a new round of quality knowledge training. 317 people signed up for the national examination on quality knowledge, including more than 100 middle-level managers and engineering technicians. We integrate the education of employees on quality knowledge with the corporate spirit of \"strictness, pragmatism, unity, civilization, and progress.\" We instill in them the awareness that \"quality is the lifeblood of a company,\" apply quality responsibilities to quality process control, and ensure that the corporate quality culture of \"quality in my heart, control in my hands\" permeates the products, thus delivering truly **inspection-free products to the market and consumers. The company has raised the focus of its management and organizes production in strict accordance with corporate standards that are higher than **the standard. The quality of products leaving the factory is governed by the principle of the integrated interconnection among four elements: standards, quality, service, and customer satisfaction. While attention is paid to the quality of products delivered, even greater emphasis is placed on the work quality of personnel at all levels and in all positions ； Not only are product standards emphasized, but more focus is placed on a standard system that takes product standards as the core, with technical standards as the main element, and management standards and work standards serving as complementary elements ； It not only helps employees realize that consumers are users, but also makes them aware that they themselves are also users in the subsequent stages of the production process and in terms of service delivery. We not only produce high-quality products but also pay attention to after-sales service, striving to maximize customer satisfaction, thereby injecting new meaning into the company’s quality culture within the framework of a model for excellent performance. Hubei Fertilizer’s \"Yangtze River\" brand urea has been designated as a **inspection-exempt product. This achievement is based on a solid quality foundation; it results from the continuous efforts of all employees who strictly adhere to the prescribed process parameters and quality standards in every stage of production. The quality mindset of \"keeping quality in mind and under control\" is applied throughout the entire process of product development, and this approach has been refined and recognized. Our quality management is striving to reach the level of enterprises with excellent performance. Our vision is to develop a large-scale chemical enterprise focused on fertilizer production, to rank among the leaders in China’s fertilizer industry, to create well-known Chinese brands, to achieve products that require no inspection, and to establish a management system based on quality management awards, all through excellence in performance ； Recreate the company’s glory.

Provide customers with eco-friendly, pollution-free products to promote sustainable social development. 6) Our brand is renowned for the saying that \"it’s still Changjiang-brand urea, no matter how many times it’s used.\" Our core values include quality, integrity, innovation, people-oriented approaches, as well as safety and environmental protection, all aimed at creating a well-known Chinese brand and achieving long-term success and a shared future. Our goal for the future is to strive toward obtaining the **Quality Management Award within a few years, by continuously innovating in management, expanding the scope of quality management, and raising the level of quality management within the company.
