Example A global consumer electronics company uses AI-powered forecasting to monitor real-time sales trends across regions. When a particular model sees an unexpected spike in demand due to viral social media coverage, the system triggers a forecast adjustment that increases order volume only in the impacted geographies. Modern forecasting solutions help break that cycle by integrating real-time demand signals and applying predictive analytics to identify patterns early.

However, don’t forget that MRP parameters such as replenishment time, reorder quantities, safety stock levels or disposal procedures need to be properly reviewed and maintained. One classic example of the bullwhip effect occurred at Procter & Gamble (P&G) when they evaluated their sales patterns for Pampers diapers, one of their leading products. It describes the process that kicks off when demand changes at the end customer (the whip holder) and these fluctuations are passed on to suppliers and ultimately producers with increasing ripple effects. Technology and data analysis can improve supply chain visibility, better understand how goods move from suppliers to customers, and potentially reduce the bullwhip effect.
Advanced forecasting techniques, such as predictive analytics and machine learning models, help supply chain participants make more accurate predictions about future demand. Incorporating real-time data, like POS transactions, can further enhance forecast reliability and reduce the tendency to overreact to short-term demand changes. This effect is named after the motion of a bullwhip, where small wrist movements cause increasingly larger waves along the whip’s length.

Customer-Driven Supply Chain Planning: How Leading Companies are Thriving in 2025
In a supply chain, the bullwhip effect leads to artificial fluctuations in supply and demand. Essentially, it means that supply gets exaggerated, and inventory builds up faster than actual demand. It is the product of disconnected systems, delayed responses and misaligned incentives. By addressing its root causes through better forecasting, tighter collaboration and operational agility, supply chain leaders can reduce volatility and drive meaningful performance gains.

Spend more time trying to understand the business processes of customers and suppliers, said Mark Struss, practice director of manufacturing operations at Patina Solutions, a supply chain consultancy. He said customers sometimes know exactly how much of a raw material they need, but don’t submit an order early because of the way early purchase orders affect their accounting processes. But these kinds of improvements require organizations to get better at aggregating all of their data into a common platform, said Amanda Wodzenski, principal at Hike 2, a consultancy focused on emerging technology. One big problem is that information for these kinds of algorithms comes from disparate systems, including marketing, sales, production and logistics applications, she said. In addition, many businesses still do their planning with monthly meetings and spreadsheets.
Understanding the Bullwhip Effect in Supply Chains
The bullwhip effect can negatively impact the supply chain, but improved visibility and transparency can alleviate these problems. SafetyCulture (formerly iAuditor) provides a solution for sellers, suppliers, 3PL, or other supply chain members, to reduce the bullwhip effect. Companies can consider implementing pricing agreements or contracts with suppliers and customers to limit price fluctuations. These agreements can establish fixed prices or price ranges that remain stable over a certain period, providing greater predictability and stability in the supply chain. Complexity often arises in supply chains that involve multiple touchpoints and players. Learn strategies to reduce the bullwhip effect’s negative impacts on your supply chain, which can result in surplus inventory, shortages, and decreased profits.
This requires understanding where the data is coming from, finding ways to layer analytics on top and then identifying emerging technology that can help. “The more you can understand about customer behavior from a common platform, the more accurately you can predict demand,” Wodzenski said. In theory, this type of approach could eventually expand across multiple supply chains, he said.
Order bundling means the retailer places larger and less frequent orders with its how to reduce the bullwhip effect supplier, which, over time, creates an inconsistent demand for the supplier. Ordering small quantities more often and consistently creates less of a whiplash effect than making bulk orders less frequently. Businesses can also reduce their order sizes, which will enable them to respond to market activity with more speed and versatility. In addition, instead of offering frequent promotional discounts which may cause sudden distortions in demand, businesses can offer standard low prices (or everyday low prices).
- This can be caused by personal preferences, aversion to risk, changes in the market, and a number of other factors.
- Even with better forecasting and collaboration, rigid supply chain designs can still fall victim to the bullwhip effect.
- This end-to-end view of risk helps companies better understand their product and production facilities, and inbound/outbound deliveries.
- By accepting this fact, companies can adopt a more flexible approach to their operations and develop strategies better suited to deal with uncertainty.
- All stakeholders in the supply chain should be aware of end customer needs, and companies in each tier are also aware of the outstanding inventory of their suppliers and customers.
Highly reactive ordering behaviors, where minor demand changes trigger significant order adjustments, are red flags. Analyzing inventory data allows organizations to pinpoint how demand variability is being amplified across the supply chain. This analysis helps in understanding the extent of the bullwhip effect and its impact on supply chain operations. The bullwhip effect is a concept for explaining inventory fluctuations or inefficient asset allocation as a result of demand changes as you move further up the supply chain. As such, upstream manufacturers often experience a decrease in forecast accuracy as the buffer increases between the customer and the manufacturer.
- Retailers need a holistic retail strategy to make distribution channels productive and to predict order peaks more easily.
- The bullwhip effect can jeopardize these efforts and lead to supply bottlenecks or even increased inventories.
- This resulted in empty shelves for months despite sufficient production capacity to meet consumer needs.
- Promotional discounts, seasonal sales, or sudden price increases can cause consumers to buy in bulk, which temporarily boosts demand.
Sales and price fluctuations
Without visibility into end-consumer behavior, upstream partners interpret order fluctuations as true demand changes, amplifying variability. Reducing the bullwhip effect starts with improving the forecasting of customer demands. With the help of inventory software, companies can control and understand how buying habits change across a period of time. When the wave of increased production peaks, demand may disappear due to seasons, trends, or new news about customs tariffs.
Manual procurement processes slow down company performance
Excess inventory is at risk of expiring or becoming obsolete, resulting in costly waste. Food items or personal care products can expire, apparel can go “out of fashion,” and electronics can become outdated and undesirable. Alternatively, you could also see increased labor demands if you run out of stock since your employees may need to work harder to arrange alternatives and solutions. Building bridges with other supply chain partners is critical to preventing the bullwhip effect. The bullwhip effect is one of the most problematic issues in supply chain management.

This way, Walmart’s staff is least involved in any errors of management in the flow of goods from suppliers to the company outlets. To prevent the bullwhip effect, retailers like Walmart have used a tactic known as “everyday-low-price” strategy. It may be evident that a large number, if not the majority, of the items in the ad, are displayed at their usual prices. Connect with a Transportation Insight expert to uncover hidden variability drivers, realign your network and build a supply chain that is built to absorb disruption, not amplify it.
Due to the summer rush in response to tariffs and the seasonal peak in logistics, production orders often do not match demand, which increases the volatility of the latter. As a result, no one understands what to expect from market prices and customer demand “pulsate” in the market at a pace that does not match the pace of producers. Suppliers, manufacturers, distributors, and retailers must collaborate throughout the supply chain to share information and coordinate activities. They should work together to develop a demand forecast based on actual customer orders and not just estimates. It can help ensure that everyone is ordering the right amount of inventory and that there is no over or under-ordering. AI can analyze large amounts of data to provide accurate consumer demand forecasting.
