Inventory is the total amount of raw materials and component parts that an organization has on hand, necessary for production and included in the factors of production.
Step-by-step explanation:
The total amount of raw materials and component parts that an organization has on hand is referred to as inventory. These items are crucial inputs and are considered part of the factors of production, which also include resources like labor and machinery used to produce goods and services.
In the context of a pizza restaurant, for example, raw materials would encompass everything from the flour, yeast, and water needed for the dough to tomatoes, herbs, and other toppings. Additional resources such as natural gas or wood for an oven and electricity for lights are also considered part of these inputs. Managing this inventory effectively is essential for the efficient operation of a business.
