Breaking down barriers to lean construction: A review of enablers and challenges

Lean building has gotten a lot of attention as a powerful way to improve project performance, cut down on waste, and boost efficiency. Still, there are some things that make it hard to use in the building industry, while other things that make it easier to use may help it become more popular. Lean building has been studied a lot, but it hasn't caught on with most construction workers yet because of a number of problems. This piece gives a thorough look at the things that help and hurt the adoption of lean methods in the building business. The review puts together what other research has found by looking at 63 pieces from well-known journals, such as 38 from Science Direct, 18 from Scopus, and 7 from Google Scholar. The choice was made through a double-blind peer-review method that made sure only high-quality study papers, articles, books, magazines, and conference materials were included. The results show that the main problems with implementing lean are resistance from organizations, cultural inertia, a lack of knowledge, bad leadership, and problems with figuring out what effects it has. Construction projects can use lean methods, but only if they have strong leadership, engaged employees, ongoing training, and rules that back them. The study says that lean building could make a big difference in how resources, prices, and time are managed in construction projects. The full use of lean methods in the building industry will be made easier by using the identified helpers and specific actions to get around the problems they cause.
