In recent years projects have increasingly used Last Planner System (LPS) in building construction. However project managers still struggle with figuring out how the LPS could be applied on their specific projects. One main reason for this struggle is that explicit instructions for systematically applying LPS are not available. This book offers practitioners and researchers an account of LPS implementation challenges and an indication of how LPS can be applied. The book qualitatively aggregates the results of 26 test case projects of LPS applications to show researchers and practitioners reasons why LPS was applied, what benefits were realized and what the challenges were found during the implementation.
