Pull vs. Push: Finding a Profitability-Driven Inventory Strategy
Now that you understand that inventory can be both a profit-driving asset, or a profit-draining liability, how do you choose an effective inventory strategy?
Two common inventory strategies prevail in the inventory management space : push and pull. If you deploy a push inventory strategy, you inventory products before they are demanded by customers, in hopes that such inventory will attract buyers and enable you to quickly fulfill orders. On the flip side, a pull inventory strategy waits to either make or inventory products until customers demand or order the products.

While the Dilbert cartoon above states a seemingly obvious solution to an inventory problem, it highlights one of the most common intracompany battles regarding inventory. Your sales side of the business desires unlimited supply of every product you sell. However, the procurement, supply, or merchandising side of your business is given the directive to manage inventory down, and only inventory what can be sold. So, what’s the solution? Are push and pull inventory strategies compatible with each other?
While push and pull inventory strategies seem completely counter to each other, in reality, most companies utilize a hybrid between the two. The hybrid arises out of balancing elements of both mindsets into a single strategy, focused on profitability. If your business is established, you have some indication of what products sell, and at what rate they sell. Ratios such as average inventory, inventory turns, and days on hand are all inventory metrics that help you understand your inventory. All such inventory metrics rely on historical data as a predictor of future behavior.
Sales can help identify deviations from historical behavior and help guide inventory strategies for the future. While push and pull strategies are helpful to understand, you will most likely deploy a combination of the two based on the costs of inventory to your business.
