The Procurement Myth: Why Diversification Is Overrated—and Reputation Is Your Real Supply Chain Strategy

At first glance, the move looked reckless.

Within 18 months, it became a competitive advantage.

While others faced inconsistent quality, delayed shipments, and coordination breakdowns, the startup secured priority production slots, preferential pricing, and early access to next-generation components.

What looked like concentration risk turned into strategic leverage.

This paradox sits at the heart of new research from IIM Ahmedabad on supplier concentration and firm performance. And it challenges one of the most deeply held assumptions in modern business:

That diversification is always the safest strategy.

The Default Logic—and Its Limits

For decades, procurement strategy has been guided by a simple principle:

Don’t put all your eggs in one basket.

The reasoning is intuitive:

• Multiple suppliers reduce dependency
• Dependency creates vulnerability
• Vulnerability leads to hold-up risk

In this view, supplier concentration is inherently dangerous—especially for startups with limited bargaining power.

And for many firms, this is true.

But not for all.

The IIM Ahmedabad research introduces a critical nuance: the impact of supplier concentration depends on your position in the network.

The Missing Variable: Relative Reputation

The study identifies three key variables that shape procurement outcomes:

1. Relative size
2. Relative reputation
3. Network position

Most founders focus on size—and assume they are disadvantaged.

But reputation and network position can compensate for, and sometimes outweigh, size.

Here’s the counterintuitive finding:

Firms with high relative reputation can benefit from supplier concentration—while those with low reputation face significant risk.

In other words, the same strategy produces opposite outcomes depending on who you are.

Two Firms, Two Realities

To understand this, consider two startups:

Startup A: Low Reputation, Weak Network

• New entrant
• Limited track record
• Minimal industry relationships

For this firm:

• Supplier concentration increases exposure
• Suppliers may prioritize larger clients
• Terms are less favorable
• Hold-up risk is high

Optimal strategy: Diversify to survive.

Startup B: High Reputation, Strong Network

• Recognized brand
• Strong investor backing
• Established industry relationships

For this firm:

• Suppliers value the partnership
• Long-term collaboration becomes viable
• Volume commitments unlock efficiencies
• Integration improves performance

Optimal strategy: Concentrate to compete.

This is not a marginal difference.

It is a strategic inversion.

Procurement as a Strategic Choice, Not a Safeguard

This insight aligns with a broader principle in strategy.

As emphasized in Bringing Science to the Art of Strategy, organizations must move from analyzing issues to making explicit choices between competing possibilities  .

Procurement is often treated as an operational function—a matter of cost optimization and risk mitigation.

But in reality, it is a strategic decision about how you position your firm in a network.

The real question is not:

• “Should we diversify or concentrate?”

It is:

• “Given who we are, which strategy creates advantage?”

The Power of Network Position

What, then, determines whether a firm can successfully concentrate?

The answer lies in network position.

Firms embedded in strong networks benefit from:

• Information flow
• Trust-based relationships
• Access to scarce resources
• Preferential treatment

In such networks, transactions are not purely transactional—they are relational.

Suppliers are not just vendors. They are partners in value creation.

This changes the dynamics entirely.

Case in Point: Apple’s Supply Chain Mastery

Consider Apple.

Despite its massive scale, Apple’s procurement strategy is highly concentrated in critical areas:

• Key component suppliers
• Manufacturing partners like Foxconn
• Long-term contractual relationships

Why does this work?

Because Apple’s reputation and network position give it unparalleled leverage:

• Suppliers compete to work with Apple
• Collaboration leads to innovation
• Integration enhances efficiency

Apple does not diversify to reduce risk.

It concentrates to maximize control and performance.

The Startup Dilemma: You’re Not Apple

Of course, most startups are not Apple.

And this is where many founders go wrong.

They imitate the visible strategies of successful firms—without replicating the underlying conditions.

Supplier concentration works for Apple because of its:

• Brand power
• Volume
• Ecosystem influence

Without these, concentration can be dangerous.

But here’s the overlooked opportunity:

Reputation is not fixed. It can be built.

Reputational Capital as a Procurement Strategy

Founders often think of reputation as a marketing asset:

• Brand awareness
• Customer trust
• Investor perception

But the IIM Ahmedabad research reframes it as something more fundamental:

Reputation is a form of bargaining power in supply chains.

A strong reputation signals:

• Reliability
• Growth potential
• Strategic importance

Suppliers respond accordingly:

• Better terms
• Priority access
• Willingness to invest in the relationship

In effect, reputation reduces the risk of concentration.

Building Reputation Where It Matters

Not all reputation is created equal.

For procurement, what matters is reputation within your industrial network.

This includes:

• Payment reliability
• Operational discipline
• Long-term orientation
• Professional relationships

A startup that pays on time, communicates clearly, and honors commitments can build disproportionate influence—even without scale.

The Hidden Cost of Diversification

Diversification feels safe—but it carries its own risks:

1. Coordination Complexity

Managing multiple suppliers increases:

• Communication overhead
• Quality variability
• Operational friction

2. Loss of Leverage

Smaller order volumes reduce:

• Negotiating power
• Pricing advantages
• Supplier commitment

3. Shallow Relationships

Transactional interactions limit:

• Innovation
• Customization
• Strategic alignment

In many cases, diversification trades visible risk for hidden inefficiency.

Integration as Competitive Advantage

When concentration works, it enables something far more powerful than cost savings: integration.

Deep supplier relationships allow firms to:

• Co-develop products
• Optimize processes
• Share information
• Align incentives

This creates a level of coordination that competitors cannot easily replicate.

It transforms procurement from a cost center into a source of competitive advantage.

Communication and Trust in Supplier Relationships

There is also a human dimension to this.

Research on effective communication shows that clarity, specificity, and trust-building language significantly influence how relationships develop  .

In supplier relationships, this translates into:

• Transparent expectations
• Consistent communication
• Clear commitments

Trust is not built through contracts alone. It is built through interaction quality.

And trust, in turn, enables concentration to function.

A New Procurement Playbook

For founders, the implications are clear:

1. Diagnose Your Position

• Do you have the reputation and network strength to support concentration?
• Or do you need diversification as a defensive strategy?

2. Invest in Reputational Capital

• Pay suppliers reliably
• Communicate proactively
• Build long-term relationships

3. Choose Strategy, Don’t Default

• Diversification is not inherently superior
• Concentration is not inherently risky
• Both are tools—use them deliberately

4. Think Beyond Cost

• Procurement is not just about price
• It is about access, reliability, and integration

5. Build Toward Concentration

• Even if you start diversified, aim to develop the conditions that allow strategic concentration over time

The Deeper Shift: From Transactions to Networks

At its core, this research reflects a broader shift in how business operates.

Firms no longer compete as isolated entities.

They compete as networks of relationships.

Your suppliers are part of your strategy.

Your reputation is part of your infrastructure.

Your network position is part of your competitive advantage.

A Final Thought

Back in that electronics startup, the decision to concentrate suppliers was not just about procurement.

It was about identity.

The founders believed they could become the kind of company suppliers would prioritize—even before they had the scale to demand it.

They invested in relationships, honored commitments, and built trust.

And in doing so, they transformed a perceived weakness into a strategic asset.

Because in the end, the strongest supply chains are not the most diversified.

They are the most trusted.
