Introduction. Ensuring the effectiveness in special circumstances is the most important factor of good implementation of the system of controlling, monitoring and diagnostics in the management practice of an agricultural enterprise. It means to be able to adapt to the conditions of formation and implementation of innovations. Obviously, this requires not only expanding the functionality of controlling, monitoring and diagnostics, but also a corresponding reorganization of management practices. Methods. Studies were conducted on the basis of general scientific methods, abstract and logical, and constructive methods. The methodological basis in preparing the material made dialectical method of knowledge of social and economic phenomena. Results. In the course of the research, the conditions for the functional efficiency development of the controlling, monitoring and diagnostics system as a coordinating system of the enterprise management were analyzed. It is established that unjustified differentiation of economic activity leads to the loss of connecting links. In this way, the monitoring function is limited by the capabilities of local controlling. The new essence of effective organization of management practice of an agricultural enterprise with the transition of its perception from the traditional model to the modern one is proved. The main function of the system of controlling, monitoring and diagnostics is determined by the goal-setting of management practice. It is proposed to use the principles of adaptive organization of the agricultural enterprise to implement the functional load of the controlling, monitoring and diagnostics system. Discussion. An adaptive organization is a dynamic system. So it requires appropriate indicators to track processes in a diverse dimension. Moreover, the effectiveness of the implementation of processes requires diagnostics for determine its optimality for replication in the current and future activities of enterprises. Determining optimality attributes requires appropriate monitoring and quick updating. Therefore, the main perspective is in systematization the information functions of controlling, monitoring and diagnostics and integrating them into the management activities of agricultural enterprises.
