Design/methodology/approach – In the present study, 116 Indian manufacturing organizations have been extensively surveyed to ascertain the inter-relationships between various success factors and competitive dimensions of SCM alone and for combined approach (TQM–SCM), through different statistical techniques. Further, to evaluate the significance of time period on competitive dimensions, two-tailed t-test has been deployed. Finally the discriminant validity test has been applied to extract highly successful and moderately successful organizations for both approaches. Findings – The study compares the contributions played by only SCM initiatives and combined approach (TQM–SCM) initiatives toward realization of significant improvements of various competitive dimensions of Indian manufacturing organizations. Finally, this study reveals that synergistic relationship of TQM and SCM paradigms can be more helpful as compared to only SCM initiatives for Indian manufacturing industries to enhance overall business performance. Originality/value – TQM and SCM are considered as performance improvement techniques by the manufacturing organizations. The present research work establishes that combined (TQM–SCM) initiatives have effectively contributed for realization of significant competitive dimensions, progressively from introduction to maturity phases. So, the study stresses upon the need for improving coordination between various manufacturing parameters as well as competitive dimensions of TQM and SCM paradigms to enjoy higher potential of business performance.

Introduction The economy of India is the tenth largest in the world by nominal gross domestic product (GDP) and the third largest by purchasing power parity. However, India lacks in manufacturing sector, because manufacturing in India is still a mere 16 percent of the country’s GDP while it is 34 percent for China and 40 percent for Thailand (Gorane and Kant, 2017). In other words, till date, India’s manufacturing sector has not performed well as compared to some other large emerging economies. Furthermore, the globalized business environment has forced organizations to shift their intra-firm focus on quality improvement to encompass the globalization of their quality strategy in whole supply chain (Li et al., 2011; Soltani et al., 2011; Wiengarten et al., 2013). Moreover, interest in quality systems adoption in supply chains is increasing due to the growing importance of global supply chains and The TQM Journal Vol. 31 No. 5, 2019 pp. 696-721 © Emerald Publishing Limited 1754-2731 DOI 10.1108/TQM-01-2019-0010 Received 9 January 2019 Revised 21 March 2019 7 May 2019 Accepted 2 July 2019 The current issue and full text archive of this journal is available on Emerald Insight at: www.emeraldinsight.com/1754-2731.htm 696 TQM 31,5
