Manufacturing plants in South Africa face significant operational challenges that affect productivity and competitiveness. The study employs mixed-methods including econometric analysis with the Fixed Effects (FE) model. Uncertainty is addressed through robust standard errors. Panel-data estimation revealed a moderate adoption rate of advanced manufacturing technologies in South African plants, indicating potential for further technological integration. This research provides foundational insights into methodological approaches for assessing and enhancing manufacturing systems in South Africa. Further studies should explore the specific factors influencing technology adoption among different sectors and regions within South Africa.
