Improvement of corporate culture as a tool for increasing change management efficiency in the sphere of the enterprise’s personnel

The article discusses the main theoretical aspects of corporate culture, its role in the functioning of modern organizations, as well as general development trends in Ukraine. It has been established that corporate culture constitutes a fundamental component of the organizational environment, as it determines the nature of internal interactions, shapes shared values, and contributes to the sustainable development of the enterprise. It acts as an integrating factor that unites employees around common norms, principles, and behavioral models, fosters organizational identity, and directly influences the level of productivity and the overall effectiveness of the organizational performance. In the current business environment, the operation of enterprises without a clearly defined corporate culture is virtually impossible, as it regulates behavioral patterns, ensures the coordination of employee actions, and creates the prerequisites for effective teamwork. It has been established that corporate culture is a tool for increasing change management effectiveness in the sphere of enterprise personnel management. In the process of change, it is carried out through a clear formulation of the mission, vision, and values, the development of management styles and leadership skills, the active involvement of personnel in the change process, the support of two-way communication, and a systematic assessment of the cultural climate in the organization. An analysis of the key challenges related to the formation and maintenance of corporate culture in Ukrainian enterprises has been conducted, including the lack of a systematic approach, the absence of clearly defined corporate values, weak internal communication, and low employee motivation. It has been demonstrated that the corporate culture of each organization must be tailored to its unique characteristics, as the mechanical adoption of external practices is ineffective without considering internal specifics. It has been substantiated that the formation of corporate values, behavioral norms, and management approaches should be based on the specific features of the enterprise, including its mission, strategic objectives, and organizational structure. Key directions for improving corporate culture and their impact on the effectiveness of human resource management have been identified. The article also outlines the sequential stages of building an effective corporate culture within an enterprise and defines the main principles that ensure its successful implementation.
