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
