THE ROLE OF THE INTEGRATED MANAGEMENT SYSTEM (IMS) IN IMPROVING PERFORMANCE IN THE AREAS OF QUALITY, HEALTH, SAFETY AND ENVIRONMENT (QHSE): A CASE STUDY OF THE ALGERIAN LOCAL PETROLEUM COMPANIES «ENAFOR & ENTP»

Objective: This study aimed to evaluate the impact of the integrated management system (SMI) on improving performance in the areas of quality, environment and occupational health and safety in Algerian petroleum companies. Theoretical Framework: The study draws on concepts of integrated management systems, which combine multiple performance dimensions to improve operational efficiency and employee well-being. Method: A quantitative approach was adopted, surveying a sample of 100 managers and employees from ENAFOR and ENTP, two local petroleum companies in Hassi Messaoud, Algeria. Data were collected via a structured questionnaire to evaluate the SMI's influence across the targeted performance areas. Results and Discussion: Findings indicate that the SMI significantly enhances worker performance, with the quality dimension contributing most prominently, while the environmental dimension has the least impact. The discussion highlights the need for comprehensive SMI implementation, emphasizing operational coordination to increase efficiency and reduce risks. Research Implications: The study suggests that Algerian local petroleum companies should adopt a more integrated SMI approach, aligning quality, environment, and safety standards to ensure sustainable performance. Emphasis on environmental improvements could further enhance worker engagement and performance outcomes. Originality/Value: This research contributes to understanding SMI's practical implications in high-risk industries, underscoring the value of an integrated approach to quality, safety, and environmental management.
