Impact of quality management systems on firm performance

Purpose: Within the operations management literature, quality management (QM) has been one of the most popular research areas over the last few decades. The impact of QM systems on firm performance has been the subject of constant interest and challenge among researchers. Last such review was done in 2002 based on QM-related articles published between 1994 and 1999 and these were primarily on Total Quality Management (TQM). In the last 18 years, a large number of empirical studies have been attempted to investigate QM system-performance relationships in different contexts, covering not only TQM but also other QM systems such as ISO 9001, Total Productive Maintenance (TPM), Lean Manufacturing, Theory of Constraints (TOC), and Six Sigma Continuous Improvement projects. The paper aims to discuss these issues. Design/methodology/approach: Based on an extensive review of 263 papers published in 17 reputed journals during the period 2000 to 2017, this paper shows the reflections of QM systems with respect to study of different QM systems, type of research designs being used, performance categories and metrics being used, and application of tools/techniques. Findings: The literature review has revealed several gaps in research in the area of QM and calls for research on: empirical longitudinal case studies; implementation of multiple QM systems; identification of leading indicators of firm’s performance; standardization of performance measures; safety, environment and health-related performance measures; the differences in the QM systems on firm’s performance for manufacturing vs service organizations; application of QM systems in developing countries including Asian countries; and impact of ISO 9001 QM system on firm’s performance. Originality/value: The literature reviews in the past had considered only the TQM-related articles published in reputed journals and did not cover other QM systems such as TPM, TOC, Toyota Production System, Six Sigma, ISO 9001 QMS, etc., which have also been widely used in many organizations, more so in the last 15 years.
