In the evolving landscape of the construction industry, the pursuit of efficiency and value optimization has led to exploring and adapting management strategies from other sectors. Originating from the manufacturing domain, particularly the Toyota Production System, lean management principles emphasize waste reduction, value enhancement, and continuous improvement. Although these principles have revolutionized manufacturing processes, their application in the intricacies of construction management presents both opportunities and challenges. Project delivery timelines, as a critical metric in construction projects, are directly influenced by the efficiency and effectiveness of management practices. As such, understanding the impact of lean management on these timelines provides insights into the tangible benefits and potential hindrances of its adoption.
