Purpose The Architecture, Engineering, and Construction (AEC) industry is witnessing a growth in the implementation of Lean principles, in particular, by teams adopting Integrated Project Delivery (IPD). This growth requires participants in these teams to possess knowledge of Lean and IPD. However, the practitioners might not have the time to participate in continuous training, nor the metacognitive awareness of their knowledge gap in these areas. This study develops an instrument to support participants in IPD teams in assessing their knowledge in implementing Lean in their projects. The instrument also aims to support these participants in gaining a metacognitive awareness of their knowledge gap and self-regulate their Lean learning journey. Design/methodology/approach The instrument was designed by leveraging literature on IPD, Lean Construction and self-regulated learning in educational psychology. Five semi-structured interviews were conducted to evaluate the instrument's face and content validity. The instrument was then deployed on three IPD projects, and survey data collected from these projects were used to validate its effectiveness. A principal component analysis was conducted to identify the most influential factors in self-regulated lean Learning assessment. Findings Based on the data from the three projects, owners and trade contractors in IPD projects implementing Lean tend to place more emphasis on Lean topics focused on understanding and fostering a collaborative environment. On the other hand, Architects, design engineers and other participants emphasize on learning and working towards a project environment based on trust. Research limitations/implications These findings inform participants on their current strengths in Lean implementation, which can be capitalized on for better project outcomes. Further, it helps identify areas that participants need to place more emphasis on their Lean journey to achieve improvements. Practical implications Through this instrument, the authors aim to support a better understanding of gaps in learning and implementing Lean principles by IPD project participants. Originality/value This paper develops a unique instrument that demonstrates how self-directed learning can be leveraged to assess the lean learning journeys of construction industry practitioners.
