Supply chain is becoming more critical and challenging than ever before due to challenging market conditions and ever-changing dynamic customer requirements. Though there are numerous ways and techniques of improving the supply chain performance, there are very few attempts being made in the context of Warehouse Management System (WMS) implementations. Hence, this research is attempted to help the supply chain industry to exhibit the Forward Vertical Integration (FVI) technique and 6-Sigma method for the effective supply chain improvement along with Beacon Technology. Forward vertical integration (FVI) is a business approach that involves business activities which include the method of the direct circulation or supply of an enterprise inventory. And, being Beacon technology is one of the leading tracker technologies that offer different functional capabilities such as power source, frequency, read range, data storage capacity and others, it has immediate benefits over the traditional barcodes. Hence, this research paper is going to investigate and publish the results when the beacon technology is integrated with the FVI-6-Sigma technique for the effective improvement of the supply chain, with the primary focus on WMS. It is evident based on the research conducted on a supply chain organization that the Beacon technology when integrated with the FVI-6- Sigma technique helps improve the performance of the supply chain, especially on the context of Warehouse Management System implementations.
