Industry 4.0 (I4) technologies are gaining increased importance in the manufacturing industry, as they can provide several benefits such as an increase in efficiency, lower costs, higher revenues, etc. This study empirically examines the critical success factors (CSF) for implementing I4 technologies in Indian automotive manufacturing industry. In this regard, CSF and performance outcomes of I4 technologies are identified from published literature. The relationships between CSF and performance outcomes are then examined by regression analysis. The results indicate that ‘Data governance’ is the most critical factor, as it affects all the four performance outcomes (operational, product, economic and responsiveness). Similarly, ‘Legal aspects’ affects three out of the four performance outcomes (operational, product and economic performance), while ‘Collaboration and teamwork’ affects only operational performance and responsiveness. The study provides an understanding of factors which are critical in achieving performance outcomes about I4 technologies in the automotive manufacturing industry. The findings can also help automotive manufacturing firms towards an informed decision making in terms of various strategies required to adopt I4 technologies successfully.
