E-Logistics2 - Essay Example This report describes the various challenges in global supply chain strategy of VF and provides recommendation to improve the â€Å"Third Way† supply chain system globally. Challenges of â€Å"Third Way† supply chain Strategy of VF VF produces apparel products from its own manufacturing plant as well as acquires apparels from other suppliers. The outsourcing strategy of VF focuses on flexibility.

Their income had reduced by 30% in the same year, but the financial condition of VF was strong. It had relatively lower debt, good credit line and comparatively higher cash than their competitors. The biggest fear for VF was the long term impact of the economic crisis on the supply chain. Several garment suppliers were operating on low margin and did not have any financial cushion.

The sudden closure of supplier’s business had proved to be troublesome for VF Company. For example, a supplier of VF had informed that it would close down its
