The Determinants of Quality Management Systems; A Systematic Review

Abstract

Quality Management Systems have become important organizational mechanisms for improving process consistency, service quality, customer satisfaction, compliance, and organizational performance. However, the effectiveness of QMS implementation varies across sectors because organizations differ in leadership commitment, quality culture, resources, employee involvement, process control, and external pressures. This systematic review aimed to identify, classify, and synthesize the main determinants influencing the implementation and effectiveness of Quality Management Systems across organizational contexts. A systematic review approach was used to identify and synthesize relevant studies on QMS, ISO 9001, total quality management practices, implementation barriers, success factors, and performance outcomes. The review process followed the logic of PRISMA 2020, including identification, screening, eligibility assessment, and inclusion. A total of 30 studies were included and summarized using a literature review matrix. The findings showed that QMS implementation is shaped by managerial, organizational, human, technical, and external determinants. Leadership and management commitment, quality culture, employee involvement and training, resources, process documentation, audit and monitoring systems, customer focus, external factors, and implementation barriers were the most frequently reported themes. QMS was also associated with outcomes such as operational performance, customer satisfaction, service quality, stakeholder satisfaction, sustainability, environmental innovation, risk reduction, and organizational learning. QMS effectiveness depends on integrated implementation rather than certification alone. Organizations are more likely to achieve positive outcomes when QMS is supported by leadership, quality culture, employee capability, adequate resources, process discipline, and continuous monitoring.
