The role of communication in effective business management

This paper examines the impact of internal communication on effective business management through a comparative analysis of two medium-sized car rental companies operating in Poland. Using a structured survey completed by 220 employees, the study evaluates 15 communication-related factors, including feedback culture, managerial accessibility, message clarity, and interdepartmental coordination. The findings indicate that Company X significantly outperforms Company Y across all evaluated dimensions, largely due to its use of advanced communication technologies, participatory models, and clear feedback mechanisms. The research highlights the strategic role of two-way communication in fostering employee engagement, organizational transparency, and operational efficiency. It contributes to the field by offering a rare, data-driven comparison within one industry and supports existing models that link internal communication to job satisfaction and motivation. Limitations include reliance on self-reported data and focus on a single industry and country. Future studies are recommended to explore cross-sector and longitudinal perspectives, especially in the context of digital and hybrid work environments.
