Explanation:

Supply chain management is fundamentally concerning with the management of a firm's reception of inputs in order to produce output, and with a firm's delivery of those outputs to the final customer.

For example, some firms can have the capability to supply their own raw materials internally, transform them into a finished product, and send the products to the customer.

Other firms have more complicated supply chains: they may buy the raw materials, produce a part of the good in a place, another part in another place, and hire another company to make the deliveries.
