Supply Chain News: Time for Regional Sourcing Models?
Supply Chain Woes from Japan Earthquake were Predictable, Given the Misapplication of Lean; Rational, Regional, Practical Supply Chains

Henry Ford could get the customer any type of Model T as long as it was black. But the Ford Motor Company now finds itself in the strange position of being able to supply vehicles in any color except (metallic) black as a result of the catastrophe in Japan.
The earthquake-tsunami that hit northeast Japan has rocked global supply chains that will be changed forever. Who knew (I didn't) that so much of the world’s production could be so devastated by disruption from a single region? Instead of simple knee-jerk responses, let us commit to leverage these events to initiate a new and total revolution in sourcing strategy. First, a quick look at how we got here.

The solution isn't just a matter of exiting northeast Japan, another knee-jerk reaction of some companies. Rather, the solution lies in totally rethinking supply chains.

What Happened?
A trend that started in the auto industry in the 1990s and became a tsunami that has now hit the whole industrial world: a radical supply model that outsourced, offshored, and "single sourced" from a single suppler often at a single plant thought to be the cheapest location in the world. Twenty years ago, Inaki Lopez at GM and then VW kicked off this revolution in automotive supply chains that quickly expanded to the whole industrial world. To be sure, a revolution was needed at that time. OEM-supplier relations in the auto industry were often too cozy and OEMs had so many suppliers they could barely identify them all. Lopez made the First Commandment of Sourcing: Lowest Global Piece Price. (And tooling costs were saved too by installing capacity at only one supplier location.)
All previous considerations of how parts related to operations went out the window.
Cozy buyer-seller relationships vanished - that's good - but sensible considerations such as total cost, quality, logistics, and partnering for mutual prosperity also disappeared.
Before long, even internal operations were held to the same pricing standards.
"Outsourcing" grew along with "offshoring," under the edict, "Match the price I can get in China or your contract goes up for bid." And up for bid they did go, and out of business they went. First, smaller suppliers closed their doors, at huge cost to OEMs to replace the lost supply of parts and materials. They were followed by larger ones. Eventually all major automotive-dedicated suppliers based in the USA filed for bankruptcy.
As a result, supply chain logistics became increasingly complex. Other trends contributed: more sophisticated software and transportation systems, for example, led to the rise of "3PL" or third-party logistics specialists. Logistics and even supply chain strategy became outsourced. Outsourcing begat outsourcing. Not unlike the specter of machines designing machines (as in the Terminator), a monster was created. In the end, yet another key competence of manufacturers was lost to specialists whose interests were their own, not the OEM's. Certainly not the customer's.
There is nothing inherently wrong with sourcing globally. But a single-minded focus on lowest piece-price with no regard to broader regional strategies leads to unneeded complexities. And, as we see from the catastrophe in northeast Japan, unneeded risk. Who knew (I didn't) that 40% of the auto industry's microchips were being produced in one relatively small region, most of them in one factory.
The simplistic and predictable reactions of some critics to question just-in-time (JIT) are, of course, not the real issues here - supply chain strategy and configuration are. In fact, semiconductors weren't being produced via JIT anyway - producing in large batches still holds sway in the electronic components industry (in fact, the electronics industry didn't need to be Lopez-ized - it was already there. Sourcing from far-flung global locations high-cost, modular componentry that quickly loses value every day it sits in the distribution system was the industry norm - mastery of which became a core competence of companies like Dell in the 1990s - even before Lopez). And yet as usual, the catastrophe in Japan has given rise to cries for the end of JIT. Minimal buffer stocks caused immediate production losses so surely the answer, according to critics, is more production and more stock. Increasing buffer stocks or finished goods inventory to buffer against a 100 year interruption is absurd.
A car has thousands of discrete parts and doesn't become a car until it has each and every one of them. "Tuxedo Black" is Ford's name for a color dependent on a unique pigment from a Merck plant close to the Fukushima Daiichi nuclear plant. It isn't produced anywhere else. Merck says the plant wasn't damaged but, due to radiation, engineers won't be able to even reenter the plant for weeks and once they do it will take six to eight weeks to set things back to order and begin producing Zirallic, Merck's name for the pigment. In the meantime, Ford can still build a truck for you, just not one in Tuxedo Black.
The deeper problem is that most companies didn't know the full extent of their exposure to risk. Buyers know their suppliers, but usually not their suppliers' suppliers, or the suppliers of those suppliers. Toyota has demonstrated remarkable ability to recover from supply disruptions in the past. Honda too: when US tariffs disrupted their steel supply ten years ago, Honda airlifted carbon sheet steel from Japan to the U.S.
A New Model for Sourcing and Logistics – Regional and Rational
Similarly, the solution isn't just a matter of exiting northeast Japan, another knee-jerk reaction of some companies. Rather, the solution lies in totally rethinking supply chains.
In general, it makes most sense to produce close to where you sell. And in general it makes most sense to engineer close to where you produce. And it certainly makes most sense to procure as close as possible to where you produce for your customers. For most large firms, that means we need regional supply strategies.
So let's use the current crisis to signal an end to 20 years of madness in sourcing strategies. Single sourcing is dangerous. That much is obvious. And 100 sources all competing for the next contract based on piece price is also dangerous, in a different way. When that single source is continents away from production facilities, the danger is magnified.
A new sourcing model is needed. The wisdom of 'dual supplier' strategies of many lean thinking supply chain managers is clear - avoid both single source and "numerous source" situations. When Deming advocated what he called "single sourcing," he was promoting OEM-supplier relationships based on partnership, not zero-sum negotiation; and on cost of quality, not price of transaction. Toyota's traditional approach was to pursue dual sourcing for first and second tier suppliers (unfortunately this did not always extend to often small third and fourth tier suppliers - thus Toyota is especially suffering from the global supply crisis since 80% of its in-vehicle computer chips were being supplied by one facility in northeast Japan with no easy re-sourcing possible). With dual sourcing, risk is avoided, such as when one supplier facility goes down, and competition is encouraged, with two suppliers in the game.
Anyone anywhere who wants to make his or her country a competitive manufacturing location needs to practice lean math. That's total cost -- including the potential cost of disruption on long-distance supply chains -- rather than the piece price plus slow freight cost calculation done by most manufacturing firms today. The USA, specifically, is already a much more "competitive" manufacturing location than most senior managers seem to think, based on the continuing decisions to send manufacturing to locations far and wide.
