Identify two primary sources of competitive advantage and give an example of each.

• A. Cost leadership (Walmart); Differentiation (Apple).
• B. Random branding and price skimming.
• C. Global expansion and outsourcing.
• D. Customer service only.

Answer: (A)

Competitive advantage comes from either delivering products or services at a lower cost than rivals or offering something distinct that customers value and are willing to pay a premium for. Walmart exemplifies cost leadership by optimizing the supply chain, achieving economies of scale, and maintaining tight cost control to offer low prices. Apple exemplifies differentiation through distinctive product design, strong brand, seamless ecosystem, and innovative features that justify premium pricing.

The other options don’t capture two enduring sources of advantage. Random branding and price skimming aren’t systematic sources of sustained advantage—branding alone is insufficient without a unique, valued offering, and price skimming is a pricing tactic rather than a fundamental position. Global expansion and outsourcing are strategic moves that can support either approach but don’t themselves define the two primary sources. Customer service alone provides only one dimension of advantage.

So, the two primary sources are cost leadership and differentiation, with Walmart showing cost leadership and Apple illustrating differentiation.
