The Impact of Integrated Management Systems (IMS) on Enhancing Performance in Quality, Health, Safety, and Environmental (QHSE) Management: A Case Study of Algerian National Petroleum Companies ENAFOR and ENTP

This research investigates the influence of the Integrated Management System (IMS) on enhancing performance within the domains of quality, environment, and occupational health and safety in Algerian petroleum enterprises. The study is grounded in the principles of IMS, which consolidates various performance aspects to optimize operational effectiveness and employee well-being. A quantitative research methodology was employed, involving a survey of 100 managers and employees from ENAFOR and ENTP—two Algerian petroleum firms based in Hassi Messaoud. Data were gathered through a structured questionnaire to assess the IMS's impact on the specified performance areas. The results demonstrate that IMS significantly improves workforce performance, with quality management yielding the greatest benefits, whereas environmental considerations exhibit the least influence. The discussion underscores the necessity of a well-structured IMS implementation, advocating for enhanced operational integration to boost efficiency and mitigate risks. The findings recommend that Algerian petroleum firms adopt a more cohesive IMS strategy, ensuring alignment among quality, environmental, and safety protocols to foster sustainable performance. Strengthening environmental management efforts may further contribute to employee engagement and overall performance enhancement. This study offers valuable insights into the practical applications of IMS within high-risk industries, highlighting the importance of an integrated approach to quality, safety, and environmental management.
