Ch2. Business Strategy — SWOT, Porter's Five Forces, and Competitive Advantage
What Is Strategy?
Strategy is a long-term plan for positioning an organization in a competitive environment to achieve sustainable advantage.
The difference between a plan and a strategy is competition. A plan is about what you will do; a strategy is about how you will differentiate yourself relative to rivals.
Core strategic questions:
- What business(es) should we be in?
- How will we compete?
- What resources and capabilities will we focus on?
Three Levels of Strategy
Corporate Strategy
The domain of top executives. Decides which businesses to be in and how to structure the portfolio.
Key decisions:
- Diversification: entering new business areas (related vs. unrelated)
- M&A: growth through mergers and acquisitions
- Divestiture: exiting low-profit businesses
Business Strategy
The level of the individual business unit. Decides how to compete in a specific market. Porter’s generic strategies (cost leadership, differentiation, focus) operate here.
Functional Strategy
Strategy at the level of individual functions — marketing, HR, operations, finance. The concrete methods for implementing business strategy.
SWOT Analysis
SWOT analysis is the most fundamental tool for strategy formulation.
| Positive Factors | Negative Factors | |
|---|---|---|
| Internal | S: Strengths | W: Weaknesses |
| External | O: Opportunities | T: Threats |
Strengths:
- What the organization does better than competitors
- Examples: powerful brand, cost advantage, proprietary technology, loyal customer base
Weaknesses:
- What the organization does worse or lacks compared to competitors
- Examples: limited distribution, aging facilities, low brand awareness
Opportunities:
- Favorable external conditions that can be exploited
- Examples: market growth, deregulation, weakening competitors, emerging technology
Threats:
- External forces that can hurt performance
- Examples: new entrants, increased regulation, substitutes, economic downturn
From SWOT to strategy: SO (use strengths to capture opportunities), ST (use strengths to counter threats), WO (address weaknesses to seize opportunities), WT (minimize weaknesses and avoid threats).
Porter’s Five Forces
Michael Porter’s Five Forces model is a framework for analyzing the competitive intensity and profitability of an industry.
1. Rivalry Among Existing Competitors
The more intense the rivalry within an industry, the lower the profitability.
Factors that intensify rivalry:
- Many competitors of roughly equal size
- Slow industry growth rate
- Difficulty differentiating products
- High exit barriers
2. Threat of New Entrants
If new competitors can easily enter, existing firms’ profits are threatened.
Factors that raise entry barriers:
- Large up-front capital requirements (economies of scale)
- Strong brand recognition
- Patents and intellectual property
- Difficult access to distribution channels
- High switching costs
3. Threat of Substitute Products
If another product meets the same need in a different way, pricing power is limited.
Example: coffee shops → energy drinks, capsule coffee machines, cold-brew subscriptions
4. Bargaining Power of Suppliers
When suppliers are few or alternatives are scarce, suppliers can dictate price and terms.
Example: commercial aviation — aircraft supply is concentrated in Boeing and Airbus
5. Bargaining Power of Buyers
When customers are few and purchase in large volumes, or switching costs are low, customers can drive prices down.
Example: large grocery chains → leverage over small food manufacturers
Porter’s Generic Competitive Strategies
Porter identifies three business strategies.
1. Cost Leadership
Producing at lower cost than competitors to maintain average margins or capture market share with lower prices.
Success conditions:
- Achieving economies of scale through high-volume production
- Efficient processes and a cost-reduction culture
- Targeting a broad, price-sensitive market
Representative examples: IKEA, Walmart, Southwest Airlines, Costco
Risk: margin erosion from price wars; if the cost advantage erodes, the strategy collapses
2. Differentiation
Providing unique value that customers will pay a premium for.
Success conditions:
- Uniquely superior value in brand, technology, design, or service
- Customer loyalty and switching costs
- Sustained innovation capability
Representative examples: Apple, Starbucks, BMW, Ritz-Carlton
Risk: differentiation costs exceed the premium; easy imitation erodes uniqueness
3. Focus
Concentrating on a specific segment (customer group, geography, product line) and pursuing either cost leadership or differentiation within that segment.
Success conditions:
- A niche market that larger competitors overlook
- Deep understanding of the chosen segment’s specific needs
Representative examples: Porsche (sports cars), specialty medical device manufacturers, USAA (military families)
Resource-Based View (RBV)
Where Porter’s Five Forces focuses on the external environment, the Resource-Based View locates competitive advantage in internal resources and capabilities.
VRIN Framework — conditions for sustainable competitive advantage:
| Condition | Meaning |
|---|---|
| Valuable | Exploits opportunities or neutralizes threats |
| Rare | Not possessed by many competitors |
| Inimitable | Difficult or costly to replicate |
| Non-substitutable | Cannot be replaced by a different resource |
Resources meeting all four VRIN criteria constitute the firm’s Core Competence.
Learning Checklist
- Can distinguish the three strategy levels (corporate, business, functional)
- Can apply SWOT analysis to a specific company and derive strategies
- Can explain each of Porter’s Five Forces and what drives each
- Can differentiate cost leadership, differentiation, and focus strategies
- Can evaluate a resource’s competitive sustainability using the VRIN framework
Key Concept Cards
SWOT Analysis ★★★★★ : Internal: Strengths · Weaknesses. External: Opportunities · Threats. SO strategy (attack): use strengths to capture opportunities. ST strategy (diversify): use strengths to counter threats. WO strategy (fix): address weaknesses to seize opportunities. WT strategy (defend): minimize weaknesses and avoid threats.
Porter’s Generic Strategies ★★★★★ : Cost Leadership: lowest-cost producer in the industry. Differentiation: unique product/service that commands a premium price. Focus: target a specific segment with either cost or differentiation. Attempting both broad strategies simultaneously = “stuck in the middle” → no competitive advantage. Memory tip: Cheaper · Different · Narrower
Porter’s Five Forces ★★★★★ : ① Existing rivalry ② Threat of new entrants ③ Threat of substitutes ④ Buyer bargaining power ⑤ Supplier bargaining power. The stronger these forces, the lower industry profitability.
BCG Matrix ★★★★★ : Market growth rate (vertical) × relative market share (horizontal). Star: high growth / high share → invest. Question Mark: high growth / low share → selective invest or exit. Cash Cow: low growth / high share → harvest cash. Dog: low growth / low share → divest or exit. Memory tip: Star = both high; Cash Cow = growth↓ share↑; Question Mark = growth↑ share↓; Dog = both low
Practice Quiz
Q. What is the strategic meaning of a “Cash Cow” in the BCG Matrix?
Low growth / high market share. No need for heavy growth investment → generates large cash flows. Used to fund other business units (Stars and Question Marks).
