E-supply chain management in the government sector involves using web-based tools to manage the procurement lifecycle electronically. This includes e-sourcing to establish contracts online and e-purchasing to requisition, authorize, order, receive, and pay for items electronically. E-procurement provides benefits like reduced costs, transparency, and a smaller environmental footprint. However, some suppliers and groups may refuse to participate electronically, requiring dual paper and electronic systems. E-procurement also may not be suitable for all procurement like complex projects with undefined requirements.
