The theme is the Model Organization Development of Cras d.o.o. This paper will present an analysis of Cras d.o.o. with the aim of strengthening its competitive advantage. The model will serve to introduce organizational changes at all levels of the enterprise. The present state will be defined, a research method will be drawn up to provide information on the treatment of the present state and to suggest improvements based on the analysis obtained. It will also analyze the business results of the company and the fluctuation of people and will explore the satisfaction and motivation of employees, will be interviewed by management, key customers and suppliers. At the same time, this paper will make a "benchmarking" analysis of two or three better and bigger companies in the same business. The segment of change will be business leadership (to see what employees think about leadership), motivation of employees, more productive organization (for less engaged time making more quality jobs), permanent education of all employees in some (communication) and specific segments (depending on the job executed). Without the organization there is no progress, there is no profit and competitiveness, because without the quality staff and the managers who manage them, no one is carrying out that organization.
