(upbeat music) Inventory is an asset that can boost an organization's inherent value when managed correctly. The following lessons will cover how inventory management works with the supply chain, how it can benefit operations management, how it can be considered for small businesses, and how it is relevant to e-commerce. Inventory as a raw material, component, work in progress or finished good will flow through a supply chain, but because of multiple factors, a mismatch occurs between the different inventory needs of supply chain stakeholders and between the various supply and demand areas. This inconsistency is not necessarily bad because the manufacture and consumption of goods will never match exactly. To illustrate this, let's imagine an overseas toy manufacturer. They must produce toys months in advance to supply the market for the holiday season. This means that the inbound side of the supply chain for these toys must start gearing up very early in the year, usually around spring. In the case of a plastic toy, the plastic resin manufacturer must have the needed resin early enough for the toy manufacturer to make toys. The toy manufacturer must produce the toys considering the lead time to transport the toys overseas to the toy retailer's warehouse. The retailer must transport the toys to the stores in time for the holiday season. So the supply chain pipeline fills up on the inbound side in anticipation of holiday sales. All of this happens even before selling one toy for the holidays. Manufacturers need to decide how many raw materials or components to buy and how many SKUs to produce. Retailers need to choose when to purchase toys and how many in order to be ready for the holidays. The supply chain must hold the different inventories, otherwise known as cycle inventory, and all parties involved must be prepared to move the inventory into the next stage of the supply chain. To determine how much of each type of inventory should be held, the cost implications as well as customer satisfaction must be considered. Having too many finished goods in the retail store can be costly, but it can also improve overall customer satisfaction. A happy customer may be one that is more likely to shop at a store again. The supply chain is an important aspect of good inventory management. With the proper management of the flow of goods, the stakeholders will remain happy. Supply chain flow planning is done through a concept called sales and operations process, or S&OP. The purpose of S&OP is to include marketing strategies with customer demand information to forecast future work. It is essential to have accessibility to the various inventory components throughout the supply chain. Additionally, having customer sales information accessibility improves the forecast to a point where the goods flow through the supply chain with minimal issues. Imagine multiple warehouses and manufacturers along a supply chain highway. The first warehouse holds all the raw materials or components for the finished good. As required, the parts move from the raw materials and components warehouse to the next warehouse or plant, changing to a work in process along the way. As the materials move along the highway, they eventually end up in the retailer's warehouse. Inventory management monitors the processes while inside each warehouse or plant. Supply chain management monitors the larger supply chain. In this scenario, inventory management is a component of supply chain management.
