Final answer:
Vendors deliver goods in the supply chain, consolidators optimize shipments to reduce costs, and sourcing agents assist companies in foreign markets with their local expertise.
Step-by-step explanation:
In the apparel supply chain, professionals play distinct roles to ensure efficient operations from sourcing to delivery. A 'vendor', about sourcing, is an entity that delivers services or finished goods to retailers or end customers. They are key players in the extended global commodity chains, providing the necessary products for international trade. A 'consolidator' is tasked with the optimization of shipment by grouping merchandise from multiple companies into a single container to reduce shipping rates, greatly contributing to cost efficiency in transport.
Lastly, a 'sourcing agent' assists a company in a foreign country by using their expertise of the local culture, bureaucracy, and industry, which is instrumental in navigating complex global supply chains and maintaining labor rights to prevent practices like sweatshops.
