The basic approaches to the function of adjusting at the modern stage of management development on the basis of analysis, synthesis, systematization and generalization of scientifically-methodological sources are reflected in the article. Its essence that consists in adjustment on results control is theoretically proved. It is set that adjusting allows supporting the system of organization at optimal level, putting in order all subsystems, providing condidtions for further perfection, shutting out an excessive reactive management (after consequences and rejections). It is found out, that an adjusting function answers the basic requirements that are pulled out to any function of management. Adjusting has the object of activity (information about the state of management object on the results of control); methods of activity (regulating, stimulating, disciplinary, administrative, which are predetermined by tasks that stand before a leader for solving the situation); relations during administrative activity (linear and functional relations which are multiplied by methods of influence – power and leadership); results of administrative activity (solving the problem). The diagnostic, educational and pedagogical value of adjusting is exposed; function principles and criteria are determined. It is set that the tasks of leader during adjusting consist of panoramically seeing all administrative functions of the cycle, their co-operation; having the proved, checked and reliable information about the necessity of changes; being able to gather the methods of correction in accordance with a situation; producing clear and rich in content recommendations in relation to organization of the system, removal of defects and carrying out verification of their implementation. Adjusting provides for arrangement of all links of organization and its activity and correction of its subsystems. Adjusting is the ability to support the system of organization at optimal quality level and to direct its development. It is proved that adjusting function, as extraordinarily important, difficult and richly in content is a ponderable factor that predetermines efficiency of modern management.
