Locked on Pallets: How a Warehouse Robot's 'Only Use' Cost a Retailer Time and Money
A real-world example of Functional fixedness in action
Context
SwiftCart is a mid-size e-commerce retailer that invested in automation to keep up with seasonal demand. The operations team purchased a robotic arm explicitly marketed and configured for palletizing incoming boxes at the receiving dock.
Situation
The robotic arm lived its life stacking and wrapping pallets on one shift while human pickers handled order fulfillment on another. During peak season the company repeatedly hired temporary pickers to meet surge demand instead of investigating whether the new robot could help with order picking.
The bias in action
Operations and engineering treated the robot as a single-purpose palletizer because that was how the vendor demonstrated it and how it was installed. Team meetings reinforced that 'this robot is for pallets,' so alternative uses were dismissed without prototyping. Even when a floor supervisor suggested testing the arm for picking and placing items into outbound cartons, managers rejected the idea as 'risky' and outside the device's purpose.
Outcome
SwiftCart continued to rely on manual pickers through the holiday quarter, incurring high temporary labor costs and longer fulfillment times. A competitor who repurposed similar equipment reduced picking labor and shortened lead times, gaining higher same-day shipment rates and better customer ratings.
