MC paradigm through the efficient management of work processes and their participants . The proposal is based on the integration of the new emerging philosophies and tools , which offer partial solutions to the considered problems that impede nowadays the efficient management of the MC diversity of options , together with other proposals that have proven successful in other sectors such as the application of Business Process Management ( hereinafter BPM ) paradigm and the use of emerging technologies , as wearables , mobile devices or smart sensors such as Internet of Things ( hereinafter IoT ) ( Fig . 1 ).

Accordingly , Lean helps the firm to define customer value focusing on activities that add value , through standardizing the types of waste and offering best practices to remove waste , achieving among other things to reduce inventory and waiting times ( Howell , 1999 ). In addition , other main focus of Lean Construction ( Koskela , 1992 , 1997 ) is to increase output value through systematic consideration of customer requirements , reduce the cycle time , simplify by minimizing the number of steps , parts and linkages , increase output flexibility , increase process transparency , focus control on the complete process , build continuous improvement into the process , balance flow improvement with conversion improvement and benchmark , and reduce variability . About eliminating variations and create workflow in a process is widely recognized the use of the LSS method ( Oguz , Kim , Hutchison , & Han , 2012 ). Six Sigma is a statistical-based methodology that provides a structured framework to organize and implement strategic process improvement initiatives to attain reductions in process variability ( Abdelhamid , 2003 ). Within the construction industry , Six Sigma has been applied independently to improve the overall performance by reducing process variability in current construction operations ( Han , Chae , Im , & Ryu , 2008 : 21-31 ), also as a quality initiative in traditional construction ( Pheng & Hui , 2004 : 482-489 ) to increase customer satisfaction and profitability ( Tutesigensi & Pleim , 2008 ). Lean principles and Six Sigma has been used by working in unison as an integrated model ( Shan & Li , 2013 : 245-252 ), also applied in traditional construction where each methodology complements the other ( Banawi & Bilec , 2014 : 58-71 ; Desale , 2013:1-8 ) in the sense that Lean does not possess tools to reduce variation and bring a process under statistical control , and in the same way , despite Six Sigma offers a lot of gains
