𝐓𝐡𝐞 𝐛𝐮𝐥𝐥𝐰𝐡𝐢𝐩 𝐞𝐟𝐟𝐞𝐜𝐭

𝐓𝐡𝐞 𝐛𝐮𝐥𝐥𝐰𝐡𝐢𝐩 𝐞𝐟𝐟𝐞𝐜𝐭 is a phenomenon that occurs when the variability in demand for a product increases as it moves up the supply chain.

When a spike in demand occurs, each party in the supply chain adds additional products to their orders to act as a buffer. When one party does this, it serves the necessary function of ensuring in-stock products. However, when everyone does it, the result is inaccurate forecasting, stock hoarding, overstock inefficiencies, and out-of-stock products later.

1. Supply chain complexity

2. Consumer expectations

3. Batched orders

The bullwhip amplifies because supply chain members don’t have a full picture of why buyers are increasing demand. Improving visibility across the chain can help everyone see the context of demand changes. 

Some tools that help here include:

Electronic Data Interchange (EDI)

Vendor Managed Inventory (VMI)

Internet of Things (IoT)

Supplier Enablement portals

2. 𝐒𝐭𝐚𝐫𝐭 𝐏𝐫𝐞𝐝𝐢𝐜𝐭𝐢𝐧𝐠

Smart predictions are key to better understanding demand changes. With a wide range of intelligent inventory software on the market, you can collect data on just about every business element and turn it into valuable, actionable insights for avoiding the bullwhip effect.

Different members of the supply chain need to work together to avoid feeling the bullwhip effect. Shared information plays a large role here, allowing different entities to collaborate and see more of the supply chain than just the level they control.

Real-time data and end-to-end visibility are essential.

4. 𝐑𝐞𝐝𝐮𝐜𝐞 𝐋𝐞𝐚𝐝 𝐓𝐢𝐦𝐞𝐬

Long lead times can exacerbate the bullwhip effect, with products arriving far after they’re needed and becoming overstock. Reducing lead times across the board and placing orders when demand is high can mitigate bullwhip issues.

Some strategies to shorten lead times include:

Using trusted, local suppliers

Investing in VMI

Hiring a logistics manager

Reevaluating your shipping methods

Automating manufacturing
