Caterpillar’s dual sourcing strategy
Caterpillar’s Dual Sourcing Strategy was born from hard lessons. In 2011, the Tōhoku earthquake halted the supply of a vital part needed during production. The result was a disrupted production process that had ripple effects across the entire supply chain.
In 2022, a supplier fire could have had the same effect. However, this time, Caterpillar’s supply chain maintained a steady production. The difference was preparation.
Key Nuggets:
- The 2011 earthquake exposed Caterpillar’s heavy reliance on a single Japanese supplier for hydraulic hoses.
- Losses hit $300 million in sales and $100 million in profit that year.
- Caterpillar responded by creating a dual sourcing strategy and stocking more inventory near plants.
- In 2022, when a U.S. supplier fire struck, Caterpillar switched to a European partner with no disruption.
- The lessons are clear: diversify suppliers, accept redundancy costs, and plan ahead.
Background Story Behind Caterpillar’s Dual Sourcing Strategy
In March 2011, the earthquake in Japan exposed a blind spot in Caterpillar’s supply chain.
Many of the company’s suppliers, which were situated in Japan, had gone offline due to the earthquake. Among these was the supplier of hydraulic hoses, a critical component required in Caterpillar excavators. With no backup source, the production of the excavator slowed.
Following the disruption, Caterpillar expected to lose approximately $300 million in sales and $100 million in profit in 2011. Although the company was eventually able to curtail the losses, it still incurred $200 million in sales and $60 million in operating profit.
Nevertheless, the financial impact was the direct cost of leaning too heavily on one supplier and holding little stock.
Before 2011, Caterpillar’s supply chain, like that of many other companies in the industry, had focused on supplier consolidation and lean inventory management to control costs.
But the Tōhoku earthquake demonstrated that depending on a single source for vital parts is a single point of failure. As risk experts noted at the time, “the reliance on just-in-time inventory and the lack of alternative suppliers” were root causes of widespread disruptions.
Following this, Caterpillar realized that its existing supply chain structure at the time was efficient in normal times but fragile in times of crisis.

Caterpillar’s Supply Chain Response: From Reactive to Proactive
Like many businesses and supply chains affected by the 2011 Japan earthquake, Caterpillar was caught with limited buffer inventory and no readily available alternative suppliers for certain critical parts.
However, Caterpillar’s supply chain adjusted its approach by making two key moves that would transform the entire operation.
1. Dual Sourcing for Critical Components
The company approved and invested in backup suppliers for key components, like the hydraulic hoses that were affected during the earthquake. Orders were split, sometimes by region. If one region failed, the other could still supply.
2. Inventory Closer to Plants
Following the incident, Caterpillar maintained a higher level of safety stock near its assembly sites, particularly for critical parts, as part of its supply chain. This raised carrying costs, but ensured that plants could continue to operate even if shipments stalled.
Making that shift showed Caterpillar’s willingness to trade a measure of cost savings for resilience. It was a clear step from a reactive to a proactive supply chain model.

The Impact Of Caterpillar’s Dual Sourcing Strategy
The payoff came in 2022 when a fire at a rubber plant in Ohio, one of Caterpillar’s hose suppliers, could have crippled production again. But instead of a repeat of the 2011 incident, Caterpillar simply switched to its European supplier and avoided interruptions.
As a result, not one of Caterpillar’s plants went idle, proving the value of supplier diversification. Experts refer to this type of planning as “redundancy in the supply chain.” What was once a weakness became Caterpillar’s strength.

Lessons From Caterpillar’s Dual Sourcing Strategy
Caterpillar’s story holds lessons for all supply chain leaders.
1. Don’t Rely on One Source.
Single-source dependency may work in good times, but it is a recipe for disruption in times of crisis. A second supplier, even if more expensive, can act as insurance. In 2011, Caterpillar paid the price of not having this. By 2022, that insurance policy paid off in a big way.
2. Balance Cost Against Resilience.
Redundancy does cost money. More suppliers and extra stock mean higher spend. But in this case, if you compare the potential loss with Caterpillar’s $200 million sales loss in 2011. Redundancy can save far more than it costs.
3. Stock Buffers Where They Matter.
Automotive supply chains tend to lean towards lean supply chains because they reduce a significant portion of storage costs. But lean can also mean brittle. Caterpillar’s post-2011 move to place extra stock near plants created a cushion.
When disruption struck, that cushion bought the company some time.
4. Culture Matters.
The most significant change was a shift in mindset. In 2011, Caterpillar had no choice but to react to disaster. By 2022, it had already planned for the worst. And a proactive culture turns crises into routine adjustments.

How African Supply Chains Can Apply These Lessons
African supply chains face frequent shocks, whether it is from the infrastructural gaps on the continent to flooding disasters and political changes; there is a constant presence of risk on the continent. Caterpillar’s strategy shows how resilience can be built.
- Diversify Suppliers: Relying on a single port, plant, or vendor is risky. Companies on the continent can source from both domestic and offshore partners. A Kenyan food processor, for example, could buy packaging both locally and from other parts of the continent.
- Invest in Safety Stock: Even modest reserves can protect against delayed imports or road closures. A Nigerian auto-parts assembler could maintain two weeks of stock instead of just a few days.
- Develop Regional Partners: Local suppliers may not match global firms at first. However, qualifying them as backup sources helps build resilience. Over time, those partners grow stronger.
- Adopt Proactive Risk Planning: Waiting for a shock is expensive. Scenario planning, such as “what happens if this port shuts?” or “what if this supplier burns down?” helps teams act quickly.

These are not theories; they are proven in practice. Caterpillar’s supply chain turned lessons from a devastating earthquake into a working strategy. The same approach can help African supply chains maintain steady production when unexpected events occur.
