Methodological Assessment of Manufacturing Systems Adoption in Nigerian Plants Using Quasi-Experimental Design,

Manufacturing systems adoption in Nigerian plants has been a topic of interest for assessing productivity improvements. The review employs rigorous methodology including systematic searching and selection processes from academic databases. Studies are critically analysed for their use of quasi-experimental design in measuring adoption rates across various sectors. A notable finding is the predominance of within-industry comparisons over cross-sectional studies, indicating a preference for local context-specific evaluations. The review underscores the importance of rigorous methodological approaches to ensure valid conclusions regarding manufacturing system adoptions in Nigerian contexts. Future research should expand on longitudinal quasi-experimental designs to provide more comprehensive insights into long-term adoption impacts. manufacturing systems, adoption rates, quasi-experimental design, Nigeria Model estimation used θ̂=argminθ∑ᵢ(yᵢ,f_θ(xᵢ))+λθ₂², with performance evaluated using out-of-sample error.
