Supply chain management (SCM) coordinates suppliers to deliver products on time and within budget. It aims to reduce costs, defects, and waste through cooperation between clients, contractors, designers, and subcontractors. Modern procurement encourages SCM to improve construction industry productivity. Total quality management (TQM) was developed in 1950 and has been successfully applied to manufacturing, construction, and other industries to achieve customer satisfaction through continuous improvement, teamwork, and defect prevention.
