This study examined corporate governance and its impact on the management of MTN Mobile Communication Nigeria Limited, Kaduna Main Branch. The research was based on well-defined research topics and used a survey research design. The whole telecommunications business in Nigeria made up the larger population, however the study sample was the MTN Mobile Communication Plc, Kaduna Branch, which had twenty-five (25) personnel. The researcher created a structured questionnaire based on a five-point Likert scale to collect the data. We used mean scores and frequency distributions to look at the data we gathered in a way that answered the study questions. The results showed that MTN uses both internal and external governance tools to control how well the organization runs. Some of the control mechanisms that were found are internal and external auditing procedures, good oversight by the board of directors, and a structured balance of power. The study also found structural problems with company management, like the high expense of keeping an eye on activities and the lack of accounting information for shareholders.
