The Primacy of Strategic Leadership and Institutional Pressures in Integrated Management Systems Implementation: An Empirical Investigation of Indian Manufacturing

Abstract

This study empirically investigates the relative contributions of strategic leadership (management commitment) and institutional pressures (external factors) to the effectiveness of Integrated Management Systems (IMS) implementation-defined as the simultaneous deployment of ISO 9001:2015, ISO 14001:2015, and ISO 45001:2018-in Indian manufacturing organisations. Drawing on Resource-Based View and Institutional Theory, two simple OLS regression analyses (H1: Management Commitment ? IMS Effectiveness; H2: External Factors ? IMS Effectiveness) are reported alongside supplementary multiple regression and mediation analysis. Data were collected from a cross-sectional survey of N = 350 respondents across nine industrial sectors in Madhya Pradesh and adjacent states. H1 was supported: Management Commitment is a significant positive predictor of IMS Effectiveness (? = .443, R² = .197, p < .001). H2 was also supported: External Factors exert a near-equivalent positive influence on IMS Effectiveness (? = .431, R² = .186, p < .001). In multiple regression, both predictors retain significant unique contributions after controlling for Employee Involvement and Implementation Challenges (R² = .273). Mediation analysis further establishes that IMS Effectiveness partially mediates the Management Commitment ? Organisational Performance pathway (indirect effect = .125, 95% CI [.065, .185], Sobel z = 4.09, p < .001). The findings advance a dual-pressure model of IMS integration and carry direct implications for policymakers, certification bodies, and manufacturing leadership in emerging economies.
