A scoping review analyzes efficiency in Nigerian manufacturing plants, indicating the need for standardized practices.
Manufacturing plants in Nigeria face challenges related to efficiency gains, which can be influenced by system design and operational practices. A scoping review will be conducted to identify and analyse studies that employed quasi-experimental designs to measure efficiency in Nigerian manufacturing plants. The review will cover literature from to the present. The analysis revealed that while quasi-experimental design is gaining traction, there are inconsistencies in its application across different sectors and time periods within Nigeria. Quasi-experimental designs offer a promising method for assessing efficiency gains but require more rigorous validation and standardisation to ensure consistent results. Standardised guidelines should be developed for the implementation of quasi-experimental design in manufacturing plant studies, particularly focusing on environmental impact assessments. Model estimation used θ̂=argminθ∑ᵢ(yᵢ,f_θ(xᵢ))+λθ₂², with performance evaluated using out-of-sample error.
