Summary

In the face of global disruptions, rising tariffs, and an evolving economic landscape, American manufacturers and small businesses are rethinking their supply chain strategies. At the center of this transformation are two critical concepts: Total Cost of Ownership and the Theory of Constraints. While these acronyms may sound similar, their integration provides a robust framework for onshoring initiatives and gives small businesses a competitive edge.

The Two TOCs You Need to Understand

Understanding and applying these TOCs can help your business make strategic decisions that reduce risk, improve profitability, and capitalize on the resurgence of domestic manufacturing.

What Is Total Ownership Cost?

Total Ownership Cost goes beyond the sticker price. It accounts for all direct and indirect costs associated with acquiring, owning, and disposing of a product or asset. TOC includes:

Acquisition costs (purchase price, shipping, tariffs)
Operating costs (maintenance, labor, utilities)
Risk-related costs (delays, geopolitical risks, quality issues)
End-of-life costs (disposal, decommissioning)

For companies sourcing from overseas, the Total Ownership Cost often exceeds expectations due to hidden costs like delays in shipping, compliance expenses, and quality control failures. Tariffs introduced in recent years have increased the landed cost of imported goods, making domestic production more attractive.

Real-World Example: Many years ago, I worked for Ford Motor Company. It was 3rd on the Fortune 500 and Global 500 at the time. One of my first total ownership costs moment came when the company offshored the production of a rack and pinion gear component. The reason for offshoring was to save money and reduce material costs. Well, that worked. Unfortunately, the total ownership cost went up by 5X for labor costs. Why? Because the offshore company did not produce a quality component. Each component was inspected 5 times before entering into production.

Unfortunately, costs also increased for rejections because, despite the multiple inspections, numerous defective components still entered production. Often, those defective components made it into production, and they went through until the end product was tested just before it was shipped. Rejecting the final product meant more material and labor costs related to all the other components in the assembly, plus all the labor, and you get the point.

The material “cost savings” was realized. Unfortunately, the total cost to the company created thousands of dollars of cost overruns.

Total ownership costs require the company to look at all costs in the business context, potential unintended consequences, and other factors.

What Is the Theory of Constraints?

Developed by Dr. Eliyahu Goldratt, the Theory of Constraints focuses on identifying and managing the single most limiting factor, the constraint, that prevents a system from achieving its goals.

In a manufacturing or operations context, the Theory of Constraints involves:

Identifying the constraint
Exploiting the constraint (maximizing its output without significant investment)
Subordinating everything else to support the constraint
Elevating the constraint (investing to remove or expand it)
Repeating the process to address the following constraint

When applied effectively, the Theory of Constraints enhances throughput, reduces inventory, and increases operational efficiency.

Why Small Businesses Need Both TOCs for Onshoring Success

The shift toward onshoring isn’t just a political or economic response; it’s imperative for business. Small and mid-sized enterprises (SMEs) can leverage TCO and TOC to optimize this transition.

Lowering Total Ownership Costs Through Onshoring

Onshoring enables businesses to control quality, reduce transportation costs, and eliminate tariff expenses. But, without analyzing Total Ownership Costs, companies might overlook operational inefficiencies or underestimate capital requirements.

Small businesses that calculate true Total Ownership Costs discover that producing domestically, while possibly more expensive per unit, yields lower total costs over time through:

Faster lead times
Fewer supply chain disruptions
Lower risk of regulatory non-compliance
Greater agility in responding to market demand

Improving Throughput with the Theory of Constraints

While bringing operations stateside, many SMEs encounter capacity constraints: labor shortages, outdated equipment, or inefficient workflows. This situation is where the Theory of Constraints becomes a game-changer.

By identifying and managing their most critical bottleneck, small businesses can:

Maximize existing resources before investing in expansion
Improve delivery reliability and customer satisfaction
Increase profitability without increasing inventory

When used in tandem, Total Ownership Costs help prioritize what to bring onshore, and the Theory of Constraints informs how to do it efficiently.

Case in Point: A Furniture Manufacturer’s Turnaround

Consider a North Carolina-based furniture maker that relied on offshore suppliers for components. Rising costs and lengthy delays forced them to reconsider their sourcing model.

Using Total Ownership Costs analysis, they discovered that offshoring saved $5 per unit on paper but cost $12 per unit in delays, rework, and lost orders. They cut their actual cost by nearly 20% by onshoring key components.

They then applied the Theory of Constraints principles to address their production bottleneck, an outdated CNC machine. Rather than buying a new one, they reallocated skilled labor and improved maintenance schedules. Throughput increased by 30% within months, and lead times dropped by half.

Positioning Your Business for the Onshoring Opportunity

The ongoing global realignment offers a golden opportunity for SMEs to reclaim market share and grow resilient operations. Here’s how to start:

Conduct a Total Ownership Cost Audit

Evaluate the real costs of your supply chain, including tariffs, risks, and time delays. Factor in both tangible and intangible expenses.

Identify Your Constraint

Map your operations. What limits your ability to scale or deliver? It could be a machine, a process, or even a policy.

Align Operations with Strategy

Use the Theory of Constraints to streamline your operations before investing in new capacity. A lean, agile domestic operation often outperforms an outsourced one bloated by delays and uncertainty.

Leverage Local Incentives

Many states and municipalities now offer grants, tax incentives, and workforce development programs for onshoring manufacturers.

Final Thoughts

The future of American manufacturing depends not just on policy shifts but on smart, strategic decisions by entrepreneurs and small business leaders. By understanding the Total Cost of Ownership and embracing the Theory of Constraints, you can unlock new efficiencies, reduce risk, and position your business to thrive in a reshoring economy.

Now is the time to build smarter, leaner, and closer to home.
