Explanation:

In economics, vertical integration is a form of company concentration. Vertical integration is therefore also referred to as vertical company concentration.  

In general, it is an organizational form with the aim of optimizing a company's value creation and supply chains.

There are two forms of vertical integration, forward and backward integration. Forward integration involves the acquisition of the business process that follows the primary business process in the production chain. Backward integration is the takeover of the business process that enters the production chain for the primary business process. An example of vertical integration is a baker who himself will process his grain for his bread, or a steel manufacturer who buys iron ore mines to produce his own iron.
