This study investigates the relationship between lean construction, organisational culture, and project performance in construction companies in Malaysia. Its main objective is to empirically investigate the moderating effect of
organisational culture on the relationship between lean construction and project
performance. Despite the wide recognition on the role of organisation culture in the
implementation of lean construction and their implication on construction project
performance, very scant empirical studies that specifically investigated these
relationships exist. Additionally, it was meant to determine the dominant culture type
in Malaysia construction companies implementing lean construction.
