Four-fold framework for process information management and the suitability of in-house developed tools in lean construction operations

This study has proposed expanding the orthodox two-fold Production Planning & Control (PP&C) model into a four-fold framework aiming to rationalize intermediate construction management activities by incorporating Lean Construction concepts while adapting them to the socio-technical characteristics of the local industry. Then, it verified the suitability of in-house-developed and joint-developed tools devised to assist existing work processes and routines, which used to operate regardless of formalized lean tenets. However, because they embed similar principles, the hypothesis that certain functions could be helpful in the realization of the Last Planner System (LPS) methodology was examined. This research has employed the Design Science Research approach to devise a process information management framework for building production that is systematic yet simple. Instantiations of three cloud applications covering different functions and project phases demonstrated a degree of complementarity so that, if combined or equipped with additional features such as constraints elimination status management and automated track record systems, they could provide handy information visualization unavailable in commercial software. The joint implementation of these tools could help realize a variation of the LPS that suits high-context culture operation environments, where advanced preparations, such as setup and arrangements to build consensus, play a key role. Introducing those existing tools into the project flow could help reduce the burden of new technology development, workflow changes, and user training. This study helped extend the range of possible applications to existing technologies by organizing their functionalities against a structured working methodology and identifying opportunities for future developments.
