Development of A Framework for Successful Last Planner System Implementation: A Systematic Review

Last Planner System (LPS), as one of the most effective lean construction tools to improve planning reliability, has been adopted by increasing numbers of construction companies worldwide. However, previous studies found that the full benefits of LPS are still hindering due to considerable problems, which prevents a wider spread of the technique. To address this gap, this study aims at developing a framework of LPS adoption for construction companies to realize the full effectiveness of LPS. A systematic literature review is undertaken to synthesize existing critical success factors (CSFs) and barriers reported in the literature, followed by a mixed-method analysis to develop an integrated framework to support successful LPS implementation. The proposed framework can be used as a checklist for construction companies to investigate the missing parts in their current operating procedure and develop a corresponding implementation strategy. With a detailed evaluation of identified CSFs and barriers, this study also reveals that project participants, the organization as well as external enablers are required to make relevant efforts in order to secure the full benefits of LPS.
