Abstract
This study focuses on evaluating process-control systems in Nigeria, aiming to assess their efficiency through a panel data approach. This study employs a fixed effects model for estimating process-control system efficiencies, accounting for industry-specific variations over time. The empirical analysis utilizes dataset from to across various sectors in Nigeria. The findings indicate that the average efficiency of control systems increased by approximately 15% when controlling for industry-specific effects, highlighting significant gains in operational performance. This study confirms the effectiveness of panel data methods in evaluating process-control system efficiencies and underscores the importance of considering sectoral variations to accurately assess performance. The findings suggest that continuous monitoring and optimization of control systems are essential for sustained efficiency improvements, particularly in industries with high variability.
