Prioritisation of lean construction barriers in Qatari context: a fuzzy AHP approach

This study identifies, reviews and prioritises lean construction barriers in Qatari context. Lean has been widely adopted in manufacturing and service sectors, but its applications in construction sector are found in scarce. The study addresses an urgent need of identifying lean construction barriers (LCBs) and its prioritisation. For obtaining a comprehensive barrier set, the study uses Scopus database. Subsequently, fuzzy analytical hierarchy process (FAHP) is applied for barrier intensity and ranking. This study prioritises 28 barriers that hinder lean adoption in construction. The results reveal that 'policy related barriers' and 'economic and managerial barriers' possess high intensity in obstructing lean adoption. The authors expect that critical review and prioritisation of lean construction barriers will help both researchers and practitioners in formulating appropriate strategies to overcome these barriers.
