The purpose of this final work was to present the implementation of the program solution for adult education Ibis in Croatia. The IBIS program is designed to provide users with easier communication and flow of information within institutions and participants and thus shortens work time and significantly increases the efficiency and reduced operating costs of institutions. It has been developed as a program solution for the many problems that we have seen in many years of work in the adult education system. The program monitors participants from its entry into the system and assignment to educational groups with all the required forms, through automatic creation of the parent book and the workbook with the directory until the final Certificate / Certificate is issued. Ibis is now used by more than ten educational institutions whose feedback helped to further develop and improve the program. Enterprises are today in a highly variable and dynamic environment, so it is very important for companies to have qualified and professional employees or managers. The manager's job is to recognize all the changes that are taking place in the vicinity of the company and to know how to react them in the best and fastest way, at a lower cost. In order for the company to resist the changes brought by the external environment, it must have a well-established business organization. It is the foundation for successful business operations. Therefore, when selecting a company structure, it must make the greatest effort to choose the right structure. Organizational business operations vary from company to company. It depends on the size of the company, the number of employees, the type of work they are dealing with, so no company can copy someone's organization. In order for a business to function successfully, the foundation for them enables a well-organized organizational structure. The organizational structure defines the work of each employee in particular, who is involved in the creation of finite products or services. This paper explains the Ibis Adult Education Software, which has greatly helped the operations of several colleges and adult education schools. The organizational structure itself, as well as the departments participating in the Ibis program, are explained. Although the current business organization of the Ibis program is well-designed and very successful, I think there is always room for continuous improvement.
