This paper is divided into two main parts: the theoretical part, which examines business functions, including their definitions, and the practical part, which analyzes each function individually using the example of the Mlinar organization. Business functions are an integral part of every organization, and are defined as a set of related work activities that carry out the tasks of the organization in a purposeful way. Business functions were created by breaking down the overall task of the organization into special tasks that are finally grouped together. Therefore, for the successful operation of any organization, it is important that each function is equally well developed in order to successfully carry out the end result or mission. The basic business functions include product research, development, procurement, production, sales, finance, and human resource management. All these functions are extremely important for achieving successful results and are present in every organization, regardless of their specific characteristics. However, the arrangement and number of these functions can vary significantly depending on the size, type, and structure of the organization, which affects how the company achieves its goals and strategies. The Mlinar organization is the largest bakery group in the Adria region that produces and sells bakery products. On the domestic market, there are about 250 branches throughout the country, and it proves its expertise by exporting to more than 20 foreign markets.
