The impact of Lean Manufacturing tools in the Supply Chain: A systematic review

Abstract

This study examines the impact of Lean Manufacturing tools on the supply chain, emphasizing their relevance in a competitive global business environment. Using the PICO, PRISMA, and Extraction (traffic light) methods, the research is structured to address specific questions regarding barriers, implementation, adaptability to changes in demand, and result evaluation. Identified barriers include workers' perception, top management involvement, and adopting sustainable practices. The need for effective leadership and communication is highlighted to overcome implementation obstacles. Adaptation to changes in demand is suggested through defined strategies, effective communication, and employee training. Lean tools such as Kanban, Just in Time, and Value Stream Mapping are emphasized as essential in optimizing the supply chain. Result evaluation focuses on performance indicators, data collection, and continuous improvement. In supplier management, Lean contributes to efficiency and collaboration, while internally, it eliminates waste and fosters a culture of continuous improvement. Lean offers agility, waste reduction, and improved communication for customer management. This summary underscores the importance of Lean Manufacturing in various aspects of the supply chain to enhance efficiency and competitiveness.
