Explanation of the Core Concepts of Total Quality Management
In the field of enterprise management, total quality management is a crucial form of quality management. It takes enterprise operation as the core goal, mobilizes all employees to actively participate, and conducts comprehensive management of all aspects of generalized quality throughout the entire process of a product, from concept to after-sales service. This not only includes ideological education but also comprehensively applies various scientific methods to ensure the scientific nature and effectiveness of quality management.
The "three comprehensives" characteristics of total quality management
1. Management of total quality
In the past, when we mentioned quality, we often confined ourselves to the narrow concept of product quality, which mainly includes the performance, lifespan, reliability and safety of products. Undoubtedly, product quality is the foundation for an enterprise to gain a foothold in the market. However, merely focusing on product quality is far from enough. Even if the product quality is excellent, but if the manufacturing cost is too high, resulting in an expensive selling price, users will surely not favor it. Similarly, even if the product quality is good and the cost is low, if the delivery is not timely or the service is not considerate, it is still difficult to truly win the recognition of users.
Therefore, enterprises must establish a broad concept of quality, namely total quality. Total quality not only includes product quality but also covers cost quality, delivery time quality, and service quality. While focusing on product quality, enterprises should strictly control costs to ensure that their products are competitive in terms of price; they should reasonably arrange production plans to guarantee on-time delivery; and they should also provide high-quality pre-sales, in-sales, and after-sales services to meet the various needs of users. Only by effectively managing all aspects of the broad concept of quality can enterprises stand out in the fierce market competition.
2. Management of the entire process
The formation of a product is a complex process that involves a series of activities of an enterprise. This process starts with market research. The enterprise conducts product research and design by understanding market demand and user preferences. Then it enters the trial - production stage, where the product is repeatedly tested and improved. Next comes the design and manufacturing of processes and tooling to prepare for mass production. The raw material supply link ensures that the materials required for production arrive in a timely and high - quality manner. During the manufacturing process, every production step is strictly controlled to ensure product quality. After the product is completed, it must pass inspection before leaving the factory to ensure it meets quality standards. Finally, there is sales service, which promotes the product to the market and provides subsequent support for users.
Users' feedback is an important part of this process, which prompts enterprises to improve their products and production processes, thus forming a complete cycle. It can be seen that the improvement of product quality depends on the work quality of each link in the entire process. Any problem in one link may affect the quality of the final product. Therefore, quality management must cover every link of the whole process, and strict management and control should be carried out for each link.
3. Management participated in by all personnel
The quality of products is a comprehensive reflection of numerous links and tasks in an enterprise, and the work of each link cannot be carried out without human participation. Everyone in the enterprise, whether working on the front - line of production or in the rear management department, whether a workshop worker or an office clerk, is directly or indirectly related to product quality.
Everyone may discover factors related to product quality in their own work. Only when everyone attaches importance to product quality, actively looks for problems in their own work and makes improvements can the product quality be continuously improved. Quality management is the responsibility of all personnel. Only when everyone cares about quality and is highly responsible for it can the product quality be truly improved and guaranteed. Therefore, total quality management requires the joint participation and efforts of all personnel.
The "Four Alls" principle of total quality management
1. Consider everything from the users' perspective - Establish the ideology of "quality first"
The fundamental purpose of product production is to meet the needs of users. Enterprises should regard users as the objects of service, which is also a concrete manifestation of enterprises serving the people. In order to maintain the reputation of products, enterprises must establish the idea of "quality first". While providing users with high-quality and inexpensive products, enterprises should also provide technical services in a timely manner to ensure that users can correctly use and maintain the products.
Within the enterprise, the slogan "The next process is the user" should be vigorously promoted. There are sequential or hierarchical work relationships among various departments and personnel in the enterprise. The service recipients of each position can be regarded as the next process. Establishing the ideology of "quality first" is reflected in providing better services for the next process. Only when each position takes responsibility for the next process can the work quality of the entire enterprise be improved.
2. Everything should be prevention-oriented - good products are designed and produced
The core requirement of users for enterprises is to ensure product quality. However, there are some one-sided views on how to ensure quality. One view holds that resolutely implementing the "three guarantees" system can ensure quality, and another view believes that strict inspections can guarantee quality. Nevertheless, these views are misunderstandings about ensuring quality.
Post-production inspection focuses on inspection to ensure quality, but it cannot fundamentally solve quality problems. Because if the root causes of defective products are not addressed, defective products will continue to appear, leading to an increase in product costs. In fact, quality is gradually formed, not suddenly produced in the last process. Therefore, comprehensive control should be carried out on the factors affecting quality during the production process, transforming the past simple and passive "post-production inspection" and "quality gatekeeping" into a strategy of "prevention first" that combines prevention and inspection, and adopting an active "prevention" strategy of "pre-production control". Through effective management of various factors in the production process, it is ensured that the products produced have high quality.
3. Let data speak for themselves - handle data using statistical methods
"Saying everything with data" means judging things based on data and facts rather than subjective impressions. In total quality management, the collection of data has a clear purpose. To accurately illustrate problems, enterprises need to accumulate a large amount of data and establish data archives.
The collected data needs to be processed before valuable information can be extracted from it. Stratification is the first step in processing and organizing data and holds special significance in total quality management. The basic method for data analysis is to draw various statistical charts, such as Pareto charts, cause-and-effect diagrams, histograms, control charts, scatter diagrams, and statistical analysis tables. Through these charts and analysis methods, enterprises can gain an in - depth understanding of the quality situation, discover potential problems, and provide a scientific basis for decision - making.
4. All work shall follow the PDCA cycle
In quality management, the PDCA cycle is a scientific and effective method. It was first proposed by Dr. Deming, an American. It includes four stages: Plan (P), Do (D), Check (C), and Act (A).
The planning stage includes formulating policies, objectives, activity plans, and management projects, etc., to clarify the direction and goals of the work. The implementation stage involves carrying out work in accordance with the requirements of the plan. The inspection stage checks the implementation of the work to determine whether it is carried out as required, identify what aspects are done correctly and what aspects have problems, and analyze the causes of abnormal situations. The treatment stage summarizes successful experiences into standards for future compliance; it also summarizes the lessons from failures to prevent similar problems from occurring again. The unresolved remaining issues will enter the next cycle for continued processing.
The work of the entire enterprise should be carried out in accordance with the PDCA cycle. All departments, workshops, teams, and even individuals in the enterprise should formulate their own PDCA work cycles based on the overall goals and requirements of the enterprise, creating a situation where large cycles encompass small ones and each cycle is closely linked. The normal operation of the small cycles ensures the smooth progress of the large cycle, driving the continuous advancement of the quality work of the entire enterprise. The PDCA cycle is applicable to the quality work in all aspects and at all levels of the enterprise and is an important tool for total quality management.
