The primary instrument was a structured questionnaire utilizing a five-point Likert scale, followed by an assessment of equipment consistency and validation of content through a pilot study involving 10 percent (2 of 14 SOCs). The data was collected online over 14 days, with the assistance of research assistants, to enhance response rates. The study established that gender diversity (β = 0.218, p = 0.003) significantly enhance organizational performance. It concluded that inclusive and diverse boards foster innovation, accountability, and effective decision-making in state-owned corporations. Recommendations highlighted the need for targeted diversity policies, leadership training, succession planning, and continuous monitoring to optimize governance. Future studies should employ longitudinal designs, explore moderating factors like leadership style and organizational culture, and incorporate qualitative insights. Expanding research beyond SOCs to private firms and SMEs, while considering digital transformation and workforce mobility, would improve applicability.
