Lean Six Sigma, ISO 9001, and organizational performance: An integrated approach

Abstract

Organizations endeavor to enhance their market positions and gain competitive advantages by either continuously improving or radically transforming their systems and processes. Despite the worldwide popularity of the ISO 9001 as a quality management platform designed to meet the demands of customers and stakeholders while adhering statutory and regulatory requirements, they still exhibits various business issues and shortfalls. Applying the theories of process management and quality management, this study seeks to develop an effective framework that addresses these challenges by integrating Lean Six Sigma (LSS) with ISO 9001 standards. Our findings demonstrate that the implementation of LSS can overcome many of the ISO 9001 shortfalls and significantly improve process efficiency, reduces waste, promote continuous improvement, and enhances customer satisfaction. Furthermore, our research shows how LSS complements ISO 9001 by fostering positive organizational change and innovation, contributing to the development of a more sustainable business environment. Through two empirical case studies, this paper illustrates the tangible impact of LSS in addressing ISO 9001 shortfalls and boosting overall organizational performance. This study makes several contributions by offering practical insights into how the integration of LSS with ISO 9001 can advance both the theory and practice of quality management, ultimately driving business excellence.
