It is proved that cost management is a dominant factor in improving the efficiency of an enterprise, but this notion has no generally accepted definition. The analysis of the evolution of the basic concepts of cost management made it possible to identify the following scientific approaches: the approach to management as a process based on the achievement of goals through the management functions; situational approach based on adaptation to new situational conditions and requires the use of methods that are appropriate in a particular situation; the system approach, which involves the construction of a cost management system, taking into account the principles that contribute to the creation of prerequisites for ensuring the effectiveness of the enterprise. Management of costs in poultry enterprises is considered as a continuous purposeful activity of the management apparatus, aimed at cost planning, the organization of cost-saving expenditure in the form of cash at all stages of the production process, control over the implementation of the production plan by all structural units of the enterprise. Organizational and economic support for the process of managing the costs of agricultural production is a system of interrelated goals, principles, functions and methods that must be balanced in order to effectively develop it. It has been established that the process of managing production costs of an enterprise includes four main stages: a strategic analysis of the internal and external environment from the standpoint of assessing the conditions of management of production costs; strategic and tactical planning of the process of management of production costs of the enterprise; realization of functional strategy of management of production costs of the enterprise; strategic, tactical, operational control and making corrective changes in the functional strategy for managing production costs.
