Different models in production and operations management include the following:

• Fordism: This refers to the system of mass production and consumption developed by the Ford Motor Company and used as the dominant form of production after World War II.

• Post-Fordism: This is the dominant form of economic production since the late 20th century. It involves a movement away from mass production and toward small-batch production and specialized markets.

• Flexible accumulation: Flexible accumulation refers to the flexible strategies companies use in an era of globalization, including the innovative use of technology and communication.

• McDonaldization: This refers to the process by which companies, modeled on fast-food chains, mass produce a product that is efficient and predictable. For example, the fare in McDonald's restaurants around the world is generally standard and predictable.

• Nikefication: This refers to the process of outsourcing production and distribution to other companies.

• Siliconism: Referring to the process of production and organization of technology firms, this process involves the production of not only physical products such as phones, but also the production of processes and applications. The process involves outsourcing production to companies, often in other countries, while people in Silicon Valley, California carry out the intellectual aspects of the work. 

In addition to what has already been mentioned, other popular models associated with production and operations management include Total Quality Management (TQM) and Just-in-Time (JIT).

Total Quality Management refers to a management model focused on providing superior quality products and services to satisfy the customer’s needs. The model does not allow room for compromise with regard to quality of the product or service, and quality remains the main focus of the entire operation. Defects and wastage within the operations are swiftly eradicated. The model supports continuous improvement and development in production and operation practices within the system.

Just-in-Time refers to a production model or system aimed at optimizing and improving the supply chain within a system’s operations. The model ensures wastage is minimized and efficiency increased by making certain that materials are only received when they are needed during production. The workability of the system is achieved through accurate forecasting.
