Abstract: Effective internal communication is critical for public institutions to align strategic objectives, facilitate information flow, and enhance employee engagement. This study examined the effectiveness of internal communication channels at the Zambia Development Agency (ZDA) in promoting timely, accurate, and accessible information, as well as fostering engagement across departments. Guided by Organisational Communication Theory and the Excellence Theory, the study adopted a pragmatic mixed-methods design. Data were collected from 64 survey respondents and 20 interview participants using structured questionnaires, semi-structured interviews, and document analysis. Findings indicate that ZDA utilizes multiple communication channels, including emails, newsletters, the intranet, departmental meetings, and one-on-one supervisory interactions. Employees generally perceive communication as timely, accurate, and accessible, with face-to-face channels and one-on-one meetings rated more positively than digital platforms. Despite these strengths, challenges were identified in interdepartmental coordination, ineffective feedback mechanisms, and limitations in digital communication platforms, which constrain two-way communication and horizontal information flow. Structural barriers such as bureaucracy, siloed departments, and resource constraints further hinder engagement. The study concludes that while ZDA’s communication system is functional, it is not fully integrated and relies heavily on top-down and interpersonal interactions. It recommends institutionalizing structured communication schedules, improving digital communication platforms, strengthening feedback mechanisms, and enhancing managerial communication skills to improve employee engagement and information flow.
