Effective organizational communication is a fundamental pillar of any organization's success and plays a vital role in ensuring coordination, increasing motivation, and improving the performance of the organization's personnel. This research aimed to investigate the role of organizational communication in enhancing organizational efficiency by using a qualitative method involving semi-structured, in-depth interviews. The theoretical foundations of this research are based on empowerment theory. The study's statistical population included 21 heads of organizations, professors, and managers, selected from public and private departments and universities in Mazar-e Sharif. Individuals were sampled purposively based on their experience in organizational communications. The findings showed that organizational communication, especially formal, two-way, trust-based communication with regular feedback, plays a key role in improving organizational efficiency. Based on the findings, in organizations with a transparent, interactive communication structure, increased responsibility, intra-organizational coordination, work motivation, and personnel innovation are more evident. In contrast, in organizations where communication is limited, one-way, or authoritarian, organizational efficiency declines. Additionally, the lack of a regular feedback system, weak trust across organizational levels, unequal access to information, and the absence of an open communication culture constitute the main obstacles to organizational efficiency. The findings of this research can help public and private organizations and universities in Mazar-e-Sharif improve their internal communication systems, strengthen personnel motivation, and enhance overall organizational performance. Future research should examine these communication strategies in diverse organizational and cultural contexts and generalize the findings to all Afghan organizations.
