The paper aims to present an overview of previous research on the application of “lean” in the construction industry, covering key aspects of recent discoveries, their limits, and potential future research directions. It makes two
contributions to the body of knowledge. It initially divides the literature to provide an overview of completed research endeavors. Second, it points out a gap in the existing body of research and suggests fresh avenues for investigation. The findings indicate that prior research has had difficulty developing a sound theoretical foundation for the subject. To support the proposed "theories," "notions," and "paradigms," more study is needed. In short, there is a big need for
more research because there hasn't been a thorough evaluation of how lean has been used in the construction industry
