Agri-food products are strictly defined by law and it is very important that each of them is protected. The protection of their name is prescribed by various laws, regulations and norms, and it is possible to implement it on the basis of their originality, geographical origin and traditional reputation. The agri-food sector is one of the most important sectors because food is really a fundamental, necessary need of every human being. Most of the distribution of these products takes place in supply chains that are actually a network of different organizations - from suppliers to end consumers. The supply chain is characterized by dynamism and complexity, which is why it is very important to know how to manage it well. Therefore, companies invest a lot of effort in the same and so much attention is paid to their processes of procurement, transport, distribution, processing, production and, ultimately, the sale of products. In the supply chains, various information is constantly transfering between all its participants, all with the aim of functioning properly and obtaining quality products. This diploma thesis will present the example of the Croatian food company Podravka d.d. which owes its success, among other things, to the quality management of its supply chain.
