AB - Lean Construction implementation is often faced with challenges in transforming training into measurable project performance, particularly when learning is detached from real project environments. Despite the growing adoption of Lean principles, there is limited information on how structured learning systems can be effectively integrated into project environments to ensure sustainable performance improvement. Therefore, this study aimed to investigate the effectiveness of a corporate-based Lean Construction learning model. The investigation was carried out using a learning model developed and implemented by PT Wijaya Karya (Persero) Tbk (WIKA) through the LCPD program. Using a qualitative case study method, an evaluation was carried out to determine the integration of classroom learning, simulations, coaching, and project-based learning within real construction projects. Furthermore, learning outcomes were evaluated using pre- and post-tests, while organizational impact was assessed through Project Time, Output, and Budget (POTOB) performance indicators. The results showed that there was a significant improvement in participants’ competencies and a 9.83% year-on-year increase in POTOB performance. This indicated that integrating Lean learning within a structured corporate roadmap enhanced workflow reliability and project performance. In line with the analysis, this study contributed by proposing an integrated model correlating Lean learning with project execution to improve organizational performance.
