For decades, supply chains were built around a fairly simple assumption: scale  wins.

Consolidate production, increase order quantities, lower the unit cost and move large volumes through centralized distribution networks. The model worked  partly because companies could treat the American consumer as exactly that:  the American consumer. One national market supported by one assortment  strategy and a supply chain designed to serve it. 

But what happens when America stops behaving like one market? 

I recently read WGSN’s Macro Forecast 2029: The United States, which  introduces an idea it calls “Many Americas”: a future in which American  identity and consumer behavior become increasingly influenced by regional  economies, communities, climate realities, demographics and local culture. 

Reading it, I kept thinking about what happens one step upstream. If demand  becomes more regional, supply chains eventually have to follow.

The Supply Chain Was Built for Scale 

For much of my career in global sourcing and manufacturing, efficiency has  been driven by consolidation. A buyer places 100,000 units instead of 20,000.  The factory gains efficiency, the mill receives a larger fabric commitment,  packaging costs improve and freight can be consolidated. On a spreadsheet,  the economics can look beautiful. 

But there is an uncomfortable question we don’t ask often enough: What  happens when those 100,000 units are no longer being bought by consumers  who want the same thing? 

The climate in Miami is not the climate in Minneapolis, and the consumer in  Los Angeles does not necessarily dress like the consumer in Dallas. Regional  demographics, income pressures and cultural influences differ. Even the speed  at which trends move can vary between markets. 

Yet much of our sourcing architecture still begins with national volume. That  disconnect creates inventory, and inventory has a habit of turning yesterday’s  sourcing efficiency into tomorrow’s markdown. 

The Cheapest Unit Isn’t Always the Cheapest Decision This is something sourcing professionals learn repeatedly. 

Suppose one sourcing strategy produces a garment at $6 with a smaller initial  commitment, while a larger commitment brings the FOB down to $5.50. Across 100,000 units, procurement can point immediately to a $50,000 product-cost  saving. 

Now suppose demand doesn’t materialize as expected and 30,000 units  eventually require a 40% markdown. At a $24 retail price, those units sell for  $14.40 rather than $24. That is $9.60 less revenue per unit, or $288,000 in lost retail revenue against the original $50,000 product-cost saving. 

That isn’t a complete profitability calculation. Duty, freight, fulfillment, returns  and other costs still matter. Nor does it mean smaller orders automatically  produce better economics. It illustrates something simpler: a lower FOB does  not automatically produce a lower total cost of inventory risk. 

That is why I believe the next stage of supply-chain optimization must move  beyond cost per unit toward cost of responsiveness. How quickly can we  replenish? Can we make a smaller initial commitment and chase demand? Can  raw materials be positioned before the final assortment decision is made? 

Those questions produce a very different sourcing conversation.

Flexibility Isn’t Free 

There is an important counterargument. Smaller commitments usually cost  more. 

Factories build efficiency around volume. Shorter production runs can mean  MOQ surcharges, higher material costs, more changeovers, less efficient  cutting and sewing, and ultimately a higher FOB. Someone has to absorb that  premium. 

The question isn’t whether flexibility is cheaper. Often, it isn’t. The better  question is whether paying slightly more before demand is proven is less  expensive than paying for excess inventory after demand disappoints. 

For predictable core products, scale may still win decisively. For fashion sensitive, climate-sensitive or highly regional products, flexibility may justify its premium. Knowing which product belongs in which model is where sourcing  strategy begins. 

When the PO Was Right and the Outcome Wasn’t I have seen this problem firsthand. 

Several years ago, I worked on an apparel program where the commercial logic was familiar: committing deeper improved the costing. The factory could  operate more efficiently, materials could be leveraged across greater volume  and the unit economics supported a larger buy. 

The program was a seasonal knit top, and the performance split almost along  climate lines. Southern and West Coast doors sold through early and were  asking for replenishment within weeks, while a meaningful share of the buy sat in northern stores waiting for weather that arrived too late to help. By the time  inventory could be rebalanced, the selling window had largely passed, and the  units we had saved money on were the ones we ended up marking down. 

The purchase order itself wasn’t irrational. Based on the information available  when it was placed, it made commercial sense. The problem was that we had  optimized the purchase order more precisely than we had optimized the  demand risk. 

A supply chain can execute an order perfectly and still produce the wrong  commercial outcome. As consumer demand becomes more fragmented, that  possibility becomes harder to ignore.

Regional Demand Requires a Different Factory  Conversation 

Regionalization does not mean abandoning global sourcing. It means becoming  much more deliberate about what gets made where, in what quantity and for  what purpose. 

Some products will continue to belong in large-scale Asian manufacturing  ecosystems where raw-material depth, technical capability and production  efficiency remain difficult to replicate elsewhere. Other products may justify  manufacturing closer to the consumer because speed and replenishment  matter more than achieving the lowest possible FOB. Still others may require a  hybrid model. 

A company might commit the predictable portion of demand to a high-volume  offshore supplier while reserving capacity closer to market for replenishment.  It might secure greige fabric earlier while postponing color, print or finishing  decisions until demand becomes clearer. 

The objective is no longer simply to identify the cheapest factory. It is to design a network in which factories have different strategic roles. 

Faster Forecasts, Same Lead Times 

AI and increasingly sophisticated demand forecasting are allowing retailers to  identify consumer signals faster. But recognizing demand faster creates value  only if the physical supply chain can respond. 

A retailer may detect a trend this week, while fabric development, production,  testing, approvals and transportation still require weeks or months. Digital  demand moves at the speed of data. Physical supply chains still move at the  speed of materials, machines and transportation. 

Closing that gap may become one of the defining supply-chain challenges of the next decade. The winners won’t necessarily be the companies with the most  sophisticated forecasts. They may be the companies that can translate those  forecasts into product quickly enough to act on them without destroying  margin. 

Regionalization Is Not Nearshoring 

Nearshoring asks: Can we manufacture closer to the consumer? 

Regionalization asks a more useful question: What supply-chain configuration  best serves this particular market and this particular product?

Sometimes the answer may be Mexico or Central America because proximity  and replenishment matter. In other cases, China, India, Vietnam, Bangladesh  or another established sourcing market may remain the right answer because  

scale, capability or raw-material infrastructure matters more. Increasingly, the  answer may involve more than one sourcing location. 

That is why I don’t believe the future of sourcing will be defined by a simple  migration from one country to another. It will increasingly require portfolio  thinking, with different suppliers and sourcing regions selected for different  strategic purposes. 

From One Supply Chain to Many 

For years, companies worked to simplify supply chains through fewer  suppliers, larger commitments and greater consolidation. There were good  reasons for doing so, and those advantages haven’t disappeared. 

But resilience, changing trade policy, climate exposure, geopolitical risk and  increasingly fragmented consumer demand are pulling supply-chain strategy in another direction: toward intentional diversification. 

If America’s consumer landscape increasingly behaves as a collection of  distinct regional markets, businesses will need to understand not only who  their customer is, but where that customer is, what influences that customer  and how quickly those needs are changing. Supply-chain decisions cannot  remain disconnected from that intelligence. 

The next competitive advantage may therefore come from something that  sounds contradictory: 

Scale where scale matters. Flexibility where flexibility matters.  Proximity where speed matters. 

After nearly two decades in global sourcing and manufacturing, I don’t think  the future belongs entirely to global sourcing or entirely to local sourcing. It  belongs to companies that know when to use each. 

Because when one market becomes many, the smartest supply chain may need  to become many supply chains too.
