Manufacturing is simply the manufacturing of products through the employment of machines, tools, labor and chemicals or biotechnological or medicinal formulation. In the industrial and developing countries, manufacturing is a crucial part of the economies. In the developed countries, manufacturing is often considered an investment for the future growth of the country. Manufacturing in the developed countries comprises of several activities like designing, producing, marketing, importing and exporting of goods. In addition, manufacturing involves the extraction of raw materials, improving quality and quantity of raw materials and energy usage.

The term ‘manufacturing’ can have various meanings. In the manufacturing of products through manual labor, the workers are paid and the output is ready for retail sale. Some other manufacturing activities include machine sewing, forming of parts, finishing products, and testing of finished product through standardization. Some manufacturing is done only at the factory level, whereas other in the final retail outlets. Some manufacturing industries are very small-scale and others may involve thousands of workers.

In some developing countries, manufacturers depend on small and indigenous mass production to build up their economy. Mass production in developing countries allows manufacturers to produce large volumes of identical goods at low costs. The larger volume of manufactured goods produced by a manufacturer generally leads to lower unit costs as the manufacturers can utilize their skills and technology to improve the quality of goods. This leads to a reduction in overhead cost and a rise in profit margins.

Manufacturing and assembling different kinds of products requires different types of technologies. Some developing countries lack the technical infrastructure required to build large-scale manufacturing plants. The foreign manufacturers purchase raw materials from the country’s manufacturers and assemble the products in factories. Some manufacturers source components and assemble them locally. Some manufacturers automate the processes used in assembling and manufacturing.

In developed countries, production techniques have evolved so that a minimal set of processes is necessary to assemble goods. Machines are used to add finishing touches to products. These machines are called factory robots. Assembly lines are built to manufacture finished goods. Automated systems called robots are used to process raw materials and finished goods.

Manufacturing involves gathering raw materials and processing them to form finished products. A manufacturer builds a factory to assemble products. The factory contains a large number of stations to assemble and process raw materials. To ensure the quality of the finished product, quality manufacturing processes are required.
