When was supply chain management developed? Supply chain management concept can be traced back to the intense competition in textile industry worldwide in 1980's. Prominent figure in the United States apparel industry formed the “Crafted with Pride in the USA Council” in 1984. They were commissioned to conduct the analysis. The results revealed that total lead-time in apparel industry took 66 weeks long from raw material to consumer; 40 weeks were spent in the warehouse or in transit.
