Company X increases inventory to allow for increased manufacturing of widgets. Example - continued : Example - continued Company X notifies part suppliers of increased demand. Suppliers increase inventory to meet demand. Moral of the story : Moral of the story Distorted information along the supply chain caused inventory levels to increase along the supply chain which may result in increased inventory costs, poor customer service, adjusted capacity and many other problems associated with the bullwhip effect. Supply Chain in Equilibrium : Supply Chain in Equilibrium Suppliers Producers Distributors Retailers Products & Services Products & Services Products & Services Information Cash Key: = Inventory Levels 10 Units 10 Units 10 Units 10 Units 10 Units 10 Units Retailers are selling product at a constant rate and price. Firms along the supply chain are able to set their inventory to meet demand. Supply Chain Disrupted : Supply Chain Disrupted Suppliers Producers Distributors Retailers Products & Services Products & Services Products & Services Information Flow Cash Flow Key: = Inventory Levels 160 Units 80 Units 40 Units 80 Units 40 Units 20 Units As demand increases, the distributor decides to accommodate the forecasted demand and increase inventory to buffer against unforeseen problems in demand. Each step along the supply chain increases their inventory (double in this example) to accommodate demand fluctuations. The top of the supply chain receives the harshest impact of the whip effect. Solving the Bullwhip dilemma : Solving the Bullwhip dilemma Improve communication along the supply chain. Retailers notifying firms upstream of sales promotions will help clarify demand signals from consumers Improved information will improve demand forecasts upstream in the supply chain. Solving the Bullwhip dilemma - continued : Solving the Bullwhip dilemma - continued Improve sources of forecast data Firms can use data from Point of Sale computer systems to derive data from forecasting Firms along the supply chain can use EDI systems to retrieve data on items that are legitimately being purchased by customers Solving the Bullwhip dilemma - continued : Solving the Bullwhip dilemma - continued Work with firms upstream and downstream in the supply chain Create smaller order increments to decrease time between orders. Order processing will become closer to real-time. Work to develop consistent pricing of products to avoid demand fluctuations from the sale of inexpensive products.
