The simplest method for inventory management control system works pretty easy; small businesses, shops, partnerships, and other forms of businesses use this method daily. This method can also refer to a visual or a look-se method where the purchase person would review the stock daily to look for items and observe whether they are scarce, overloaded, or if there are any improvements to be done. He also places orders when there is a gap or a need for items in the inventory and when the minimum level is believed to be reached.

Here in this method, items are classified separately into groups (usually about three groups according to the annual costs of items used and the ranks of usage) to control and maintain a stable structure because it is greatly believed that the inventory system is also the main organ in a business that when stops abruptly, can flutter the whole productivity system and can affect other areas of a business as well.
