The supply chain is a key element of every company's business, regardless of its activity, size and other characteristics. This term refers to the system of all activities that transform natural resources, raw materials and other components into a finished product that is ultimately delivered to the end customer, and its structure is different from company to company. Although the supply chain is not easy to define, there is no doubt that it focuses on the flow of products, services and information. The complexity of the supply chain is also proven by the worldfamous company Samsung, which takes great care of its supply chain, sustainable, responsible and ethical business. At the same time, this company constantly supports its suppliers in building a stronger competitive advantage in order to establish a healthy corporate ecosystem and a sustainable supply chain. Also, she constantly evaluates and checks them in order to be sure of their quality, credibility, fairness and honesty. It monitors and adequately rewards its employees, who are key to its long-term success, and treats customers in such a way that it constantly communicates with them, listens to their requests, needs and wishes, and adapts its products and services to them. Therefore, the Samsung company is an example of good practice of a sustainable supply chain, and many other companies should emulate it.
