OM in the News: JIT Makes a Retail Comeback

Retailers are reviving an old playbook to manage their inventory levels after four years of struggling to find the sweet spot of holding enough merchandise but not too much, reports The Wall Street Journal (Jan. 24, 2024). They have worked through the excess inventory that piled up on store shelves and in warehouses over the past 18 months, and are now focusing on replenishing items rather than stocking up on goods to have on hand in case of supply-chain disruptions.

The shift marks a return to the “just-in-time” inventory management strategy (our topic in Chapter 16) that many companies had employed before pandemic-driven product shortages and volatile shifts in consumer demand prompted a switch to a “just-in-case” stockpiling approach. Companies are now better able to predict shopper demand and feel they can hold leaner inventories amid moderating spending growth and fewer supply-chain disruptions. They prefer not to hold large inventories because the excess stock ties up capital, requires more space and people to manage it, and runs the risk of becoming outdated as trends change.

“Retailers have more confidence in the overall supply chain and the logistics network and the environment, and as a result, they’re saying we’re at a point now where we’re safe to go back to JIT,” says Ohio State U. Prof Terry Esper. The SCM head at Tailored Brands adds: “The ability to react to changes in demand means the company has no need for ‘safety stock’ inventory.”

Retailers such as Walmart have rolled out technology aimed at fixing forecasting tools that were broken during the pandemic as they seek to better understand what consumers are buying and more accurately predict demand. The technology is allowing merchants to have smaller, more accurate shipments than they have in the past. “We’re able to better predict lead times, we’re able to better execute review cycles, and as we do that better, we’re able to hit target inventory levels,” says Walmart’s VP for SCM.

Still, new supply-chain disruptions could prompt a different approach and bring in more excess stock. Recent attacks by Houthi rebels in Yemen on containerships have pushed companies to reroute shipments over longer distances to avoid the Suez Canal, and low water levels at the Panama Canal have slowed some deliveries.

Classroom discussion questions:
1. Why the return to JIT?
2. Will there be less volatility in supply chains from this point on?

OM in the News: The Case for “Just-in-Case” Inventory

amazon warehouseAn interesting article  in The New York Times (Feb. 13, 2013) proposes that major storms, like Hurricane Sandy, and longshoreman strikes are causing companies to rethink the popular JIT  business model, in which only small amounts of inventory are kept on hand, to fashion just-in-case inventory management. The shift has led retailers and logistics companies to alter supply chains by adding distribution hubs. Just-in-case inventory helps retailers keep merchandise on store shelves in the event a supply chain disruption affects one of the major distribution markets.

 Since the 1990s, JIT has made sense for companies looking to reduce the cost of keeping large inventories on hand. Technology enabled retailers and manufacturers to closely track and ship items to replace merchandise sold or components consumed in production. The model also reduced transportation costs, because goods would be shipped only as necessary. Now, more companies are trying to strike a balance between “carrying the minimum inventory possible, yet never running out of things.”

For example, Houston’s Ranger Steel,  a massive steel plate distributor, recently expanded its network of distribution centers. Until the late 1990s, Ranger  regularly trucked its products directly from Houston to customers throughout the US. “For a long time that concept worked like a charm,” said the company’s VP. “Then you started to see the spike in fuel pricing, and new governmental rules that made truck transportation very expensive.” So like many retailers and wholesale suppliers, Ranger has added 7 distribution centers to its network, cutting delivery times to 24 hours by moving its inventory closer to customers. Multiple, well-placed distribution centers minimize the time and distance spent on the final leg of delivery, when trucks are often nearly empty while transporting individual items. “The final mile is the most expensive cost per pound or cost per piece,” writes The Times.

Discussion questions:

1. Why is “just-in-case” being proposed as a JIT alternative at this time?

2. Is the concept of JIT fading?
