What Is Just-In-Time Inventory (JIT)?

Reduces overstocking. “JIT reduces the risk of overstocking, freeing cash that would otherwise be tied up in inventory,” says Evelyn Xiao-Yue Gong, assistant professor of operations management at Carnegie Mellon University’s Tepper School of Business.

Exposes problems. “Because JIT operates with minimal buffers, it also quickly exposes process problems such as quality issues, bottlenecks and unreliable lead times for the business that might otherwise remain hidden,” says Gong.

Analyze your current structure. To know if JIT will work for you, you first have to better understand your current operation. Gong recommends assessing your lead times and variability, stockout frequency and impact, forecast accuracy, supply-chain reliability, defect rates and the existing pull signals for each component.

Reach out to suppliers. JIT inventory won’t work if your suppliers aren’t on board. “Work with suppliers to revise contracts and service levels to support smaller lots and more frequent, reliable deliveries,” says Gong.

The Retail Storage Hiding Under the Champs-Elysees

Storage space nearby costs upwards of $400 per square foot, and with 3,000 cars an hour clogging the avenue and 100,000 pedestrians strolling its sidewalks daily, shipping in and out is a logistical nightmare. Atelier Logistique aims to ease this situation by creating a facility that lies within 20 minutes’ ride by cargo bike of 4,400 retail stores.

“For retailers, this can be a market differentiation,” says Evelyn Xiaoyue Gong, assistant professor of operations management at Carnegie Mellon University’s Tepper School of Business. “They can deliver much faster and satisfy demands much faster, which is especially important for tourists who are only in the city for a short time.”
