Conclusions In this paper we have presented a theoretical model for the management of the variability that carries MC on the building execution in traditional construction. We have implemented a prototype model which has allowed showing its viability and has highlighted how the implementation of a representative set of techniques achieve the application of MC with efficiency, productivity, agility and change management integration. The main contributions of this work are that is the first time that BPM is applied to the field of construction in general, and in particular in the building execution phase; achieving the principles of standardization, automation, agility, flexibility and integration through an integral management model for MC in traditional construction. Also the integration of Lean and BPM paradigms; in particular, WWP of the Last Planner process, that until now only some theoretical proposals offered the synergy benefits of them, but none of them are focused on the specific area of construction. Furthermore, everyday items based on the paradigm IoT, such as wearables, have been incorporated to facilitate the integration participants-processes-technology, giving transparency, usability, flexibility and accessibility features. Finally is presented a redesign and standardization of the flooring process through the BPMN.
