Abstract

 

Abstract Organisational culture is increasingly recognised as a critical determinant of employee performance and overall organisational effectiveness. Despite its acknowledged importance, research examining the specific cultural dimensions of communication style and organisational structure in the context of private investment companies in Abuja, Nigeria, remains limited. This study examined the effect of organisational culture specifically communication style and organisational structure on employee performance at Garki Investment Limited in Abuja. A census sampling technique was adopted, targeting all 57 employees of the organisation. Structured questionnaires were distributed, of which 49 (86%) were validly completed and returned. Data were analysed using Partial Least Squares Structural Equation Modelling (PLS-SEM) via SmartPLS 3. Measurement model assessments confirmed adequate indicator reliability, convergent validity (AVE > 0.50), and discriminant validity (HTMT < 0.90). Results from the structural model revealed that communication style has a significant positive effect on employee performance (β = 0.387; T = 8.505; p < 0.001), and organisational structure also has a significant positive effect on employee performance (β = 0.477; T = 10.943; p < 0.001). The two predictors jointly explained 48.6% of the variance in employee performance (R² = 0.486). Both null hypotheses were rejected. The study concludes that well-structured communication practices and clearly defined organisational structures are key enablers of employee performance. Recommendations are provided for management practice and future research.
