Operation management puts more emphasis on operation as the center, which reflects the requirements of the development of the times. Simply put, production/operation/operation management is the process of converting input resources (factors of production) into output (products and services) according to specific requirements. Therefore, it is one of the most basic functions of all organizations.

The main objectives to be controlled by operation management are quality, cost, time and flexibility (flexibility/flexibility/agility), which are the fundamental source of corporate competitiveness. Therefore, operation management plays an important role in business operations. Especially in the past two to three decades, the scale of production and operation of modern enterprises has continued to expand, the technology and knowledge intensity of the products themselves have continued to increase, the production and service processes of products have become increasingly complex, and the market demand has become increasingly diversified and varied. The increasingly fierce competition, these factors make the operation management itself is constantly changing. Especially in the past ten years, with the rapid development of information technology, new and powerful methods have been added to operations, and the research of operations has entered a new stage, making it richer in content, wider in scope, and more complete.

The scope of modern operation management is getting bigger and bigger. The scope of modern operations has expanded from traditional manufacturing companies to non-manufacturing companies. The research content is also not limited to the planning, organization and control of the production process, but expanded to include the formulation of operational strategies, the design of operational systems, and the operation of operational systems. The operation strategy, new product development, product design, procurement and supply, manufacturing, product distribution and after-sales service are regarded as a complete "value chain" and integrated management.

With the intensification of the global economic integration trend, "global operation" has become an important topic of modern enterprise operation. Therefore, global operation has increasingly become a new hot spot in operations. Flexibility of the operating system. The diversification of production and operation is contradictory to high efficiency. Therefore, under the premise of diversification of production and operation, striving to do a good job in professional production and operation, and realizing the organic unity of diversification and specialization are also the direction pursued by modern operations.

To achieve this, efforts are made to promote flexible operation systems in modern operation practices. For example, concurrent engineering, rapid prototyping, virtual manufacturing technology, CAD/CAM technology, modular technology in product design, CNC machine tools, flexible manufacturing cells, group technology in product manufacturing, etc. Supply chain management has become an important part of operation management. Enterprises have begun to devote themselves to the rationalization and optimization of logistics, information flow and capital flow in the entire supply chain, forming alliances with enterprises in the supply chain to cope with the increasingly fierce market competition.
