To improve LPS implementation performance, it is necessary to examine how social mechanisms within LPS influence team performance, with particular attention to social interactions. Although prior case studies suggest that certain communication behaviors may be associated with LPS performance, their analyses often involve substantial uncertainty and limited capacity to isolate and quantify behavioral effects. To address this gap, this study conducted an immersive virtual reality (IVR) experiment, where LPS was implemented while minimizing involvement of potentially confounding factors, thereby exclusively examining the association between communication behaviors and team performance. Correlation and regression analyses indicate that frequency of formative communication was positively correlated with team performance, while negotiation and identification behavior were the two strongest predictors. These findings provide empirical grounding for improving commitment management system (CMS) and for developing behavior-based machine-learning models to predict team performance in LPS contexts. }, author_keywords={Last Planner® System, collaboration, language action perspective, performance, immersive virtual reality. }, address={Singapore, Singapore }, issn={2789-0015 }, publisher={ }, language={English}, document_type={Conference Paper}, source={IGLC}, }
