The Board Structure and Dynamics’ Implications on Management Performance in Sub-Saharan Africa

This work critically examined board structure and underlying dynamics, and their implications for management performance, with a precise emphasis on selected deposit money banks in the Nigerian Exchange Group (NEG). The study discussed chronic governance issues in emerging economies, including poor management, excessive executive power, concentrated ownership, and weak accountability systems. The study focused specifically on the impact of boardroom relationships and board characteristics on management performance in Nigeria’s banking sector. The research used a quantitative approach within a positivist paradigm and an explanatory research design. Selected deposit money banks’ audited annual reports and governance disclosure data were also used as secondary data, which spanned from the year 2018 to 2025. Descriptive statistics, correlation analysis, and fixed-effects panel regression were used for data analysis. The results indicate that board size, board independence, gender diversity, and number of meetings had a positive and significant impact on management performance. In contrast, ownership concentration and leadership dominance had a negative impact on managerial effectiveness. The study found that the effectiveness of governance is not merely about the formal organisational structure of boards, but also about the internal dynamics of how members interact and how power is distributed within the boardroom. The study thus made recommendations for enhanced governance reforms, specifically focused on board independence, diversity, even distribution of leadership on the board, and the board’s participation in decision-making. The study contributed to the literature on governance by combining structural and behavioral aspects into a single analytical framework.
