Methodological Assessment of Process-Control Systems Adoption in Ghana Using Panel Data Analysis

Process-control systems (PCSs) have been adopted in various manufacturing industries worldwide to enhance efficiency and quality control. A mixed-method approach combining qualitative insights with quantitative analysis. Panel data from 20 manufacturing firms were collected over a five-year period to estimate adoption rates and analyse determinants. Panel-data estimation revealed that investment in PCSs was significantly higher among larger enterprises (over $1 million) compared to smaller ones, indicating resource constraints as an influencing factor. The study provides robust estimates of PCS adoption rates in Ghanaian manufacturing sectors and highlights the importance of financial resources for successful implementation. Future research should focus on developing targeted interventions to support small enterprises in adopting advanced PCSs. The maintenance outcome was modelled as $Y_{it}=\beta_0+\beta_1X_{it}+u_i+\varepsilon_{it}$, with robustness checked using heteroskedasticity-consistent errors.
