This research aims to examine the role of the Just-In-Time (JIT) production system in enhancing the competitiveness of industrial and service enterprises. The JIT system relies on reducing waste in production processes, improving product quality, and increasing operational efficiency, enabling companies to achieve a sustainable competitive advantage. The research examines the concept of JIT, its main principles, and the requirements for its success. It also analyzes the relationship between implementing this system and achieving competitiveness through improved productivity, reduced costs, and rapid response to market needs. The research also reviews some practical experiences of implementing JIT in successful global companies such as Toyota and identifies the challenges that organizations may face when adopting this system.
The research concludes that effective implementation of JIT requires strong administrative support, the development of a flexible supply chain, and the use of modern technologies in production and management. The research also provides recommendations for organizations seeking to enhance their competitiveness by adopting this system.
