Abstract:
Lean Design Management (LDM) is a concept, which ensures efficiency and effectiveness of the design stage of a construction project to reduce uncertainty and improve the quality of the final product. Stakeholder Management (SM) is an effective approach for coordinating and managing stakeholders who involve with a construction project to ensure better relationships and reduce the complexity of the project. The integration of LDM and SM concepts together into the pre-construction phase provides a positive impact on the project performance. This paper aims to investigate the lean design management practices associated with stakeholder management in the pre-construction phase of construction projects in Sri Lanka. The research has used mixed method research approach to achieve the aforementioned aim. The research concluded that twenty-nine lean design management practices and eight stakeholder management practices can be integrated into the pre-construction phase in Sri Lanka. The findings further revealed that waste reduction, product performance enhancement, and functionality enhancement can be achieved by integrating LDM and SM practices together into the pre-construction phase in Sri Lanka.
