The rapid development of Off-site Construction (OSC) has closely linked it to Lean (LC). importance design been highlighted in LC as the primary means produce value clients. However, adoption lean thinking is still modest design. Although most research target theories and their or OSC, there limited understanding terminological cross-sectoral problems without sufficiently considering different ...
