The Porter’s Five Forces Model is a strategic framework developed by Michael E. Porter to analyze the competitive structure of an industry. It helps businesses understand the level of competition, profitability, and attractiveness of an industry.
The model identifies five key forces that influence industry competition and determine long-term profitability.
1. Threat of New Entrants
This force examines how easy or difficult it is for new firms to enter an industry.
When entry barriers are low, new competitors can enter easily, increasing competition and reducing profits.
When entry barriers are high, existing firms are protected.
Common entry barriers include:
Example:
Telecom and airline industries have high entry barriers.
2. Bargaining Power of Buyers
This force refers to the ability of customers to influence prices and quality.
Buyers have high bargaining power when:
-
Many alternatives are available
-
Products are standardized
-
Buyers purchase in large volumes
Buyer power is low when products are unique or switching costs are high.
Example:
Online consumers have high bargaining power due to multiple choices.
3. Bargaining Power of Suppliers
This force analyzes how much control suppliers have over prices, quality, and availability of inputs.
Suppliers have high power when:
-
Few suppliers exist
-
Inputs are unique
-
Switching suppliers is costly
Supplier power is low when many suppliers are available.
Example:
Chip manufacturers have high power in the electronics industry.
4. Threat of Substitute Products
Substitutes are alternative products that satisfy the same customer need.
The threat is high when:
-
Substitutes are easily available
-
Prices are lower
-
Switching costs are minimal
Example:
Tea and coffee are substitutes for each other.
High threat of substitutes limits pricing power and profitability.
5. Competitive Rivalry
This force represents the intensity of competition among existing firms.
Rivalry is high when:
-
Many competitors exist
-
Industry growth is slow
-
Products are similar
-
Price wars are common
Example:
Fast-moving consumer goods and smartphone industries.
Conclusion
Porter’s Five Forces Model helps firms:
-
Understand industry competition
-
Identify profit potential
-
Develop effective competitive strategies
Although the model is simple, it remains highly relevant when combined with modern tools and market analysis.
