While the primary element of logistics is ensuring the delivery of a product, logistics also serves many other functions. These functions include warehousing, inventory management, order fulfillment, scheduling and the coordination of other logistics providers. Additional functions of logistics management include customer service, coordinating with manufacturers, sourcing and procurement. Information technology is one of the most important parts of logistics management. Technology now allows businesses to locate a product any time of the day or night at any location around the world.
