Bill of materials in the context of "Industry (manufacturing)"

Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of the secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers).

Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed into a final product. The manufacturing process begins with product design, and materials specification. These materials are then modified through manufacturing to become the desired product.

A production order is an order issued within a company to produce a specific quantity of material within a certain timeframe. A production order may be issued pursuant to a sales order, and its issuance triggers a number of events. If components in the bill of materials are in stock, reservations are generated for those items; if they are not in stock, then requisition orders may be generated. Requisition orders may also be generated for production that occurs externally to the firm. Planned costs for the order are also generated and capacity requirements are generated for the work centers. It is mostly used in trading.
