Porter's Five Forces Framework
1. Competitive Rivalry (How intense is competition?)
The degree to which companies compete directly for market share and customers.
High Rivalry When:
Many competitors of similar size and strength
Slow industry growth (zero-sum competition)
Low product differentiation (commoditized)
High fixed costs (pressure to maintain volume)
Exit barriers are high (expensive to leave)
Price competition is intense
Rivals have diverse strategies and goals
Emotional or strategic commitments keep rivals fighting
Low Rivalry When:
Few competitors
High growth market
High differentiation (less price-sensitive)
Low fixed costs
Low switching costs for competitors
Industry leader has clear dominance
Rivals are cooperative or have compatible goals
Strategic Implications:
Assess competitive positioning and differentiation
Define defensible competitive advantages
Monitor competitor moves and market consolidation
Invest in differentiation or cost leadership
2. Supplier Power (How much power do suppliers have?)
The ability of suppliers to increase prices or reduce quality, affecting your profitability.
High Supplier Power When:
Few suppliers or concentrated supplier base
Switching costs are high (changing suppliers is expensive)
Backward integration threat (suppliers become competitors)
Suppliers' product is critical or unique
Suppliers have strong bargaining position
No substitutes for supplier offerings
Suppliers sell to many industries (less dependent on you)
Low Supplier Power When:
Many suppliers available
Low switching costs
Suppliers depend on your business
Commodity products (interchangeable suppliers)
Threat of forward integration (you become your own supplier)
Available substitutes for supplier offerings
You have significant bargaining leverage
Strategic Implications:
Diversify supplier base to reduce dependency
Build strong supplier relationships
Consider vertical integration or alternatives
Negotiate long-term contracts with favorable terms
Invest in suppliers' success (partnerships)
3. Buyer Power (How much power do customers have?)
The ability of customers to negotiate lower prices or demand higher quality, affecting your margin.
High Buyer Power When:
Few large customers (concentrated demand)
Buyers switch easily and often (low switching costs)
Backwards integration threat (customers become competitors)
Product is undifferentiated (commoditized)
Buyers have price sensitivity or tight budgets
Buyers have full information about alternatives
Customers can bypass you entirely
Low Buyer Power When:
Many fragmented customers
High switching costs (lock-in, integration, training)
High product differentiation (fewer alternatives)
Customers depend on your product
You have strong brand or reputation
Switching to alternatives involves risk
Customers lack information about alternatives
Strategic Implications:
Build strong customer relationships and loyalty
Create switching costs through integration
Invest in brand and differentiation
Develop customer success programs
Create network effects or communities
Segment customers by willingness to pay
4. Threat of Substitutes (Are there alternative solutions?)
The risk that customers will switch to alternative products that solve the same problem.
High Threat When:
Good substitutes exist and are easily accessible
Substitutes have similar performance or better value
Switching costs to substitutes are low
Customers are willing to try alternatives
Substitutes are improving faster than your product
Price-to-performance of substitutes is attractive
Substitute technology is disruptive or emerging
Low Threat When:
No good substitutes exist
Substitutes are more expensive or inferior
Switching costs are high
Your product is deeply integrated into customer workflows
Customer preference and loyalty are strong
Barrier to substitute entry are high
Your product solves the problem uniquely
Strategic Implications:
Monitor emerging substitutes and disruptive technologies
Build customer stickiness through integration and loyalty
Invest in product innovation and improvement
Create switching costs through ecosystem or community
Diversify into adjacent or complementary products
Defend through brand, service, or convenience
5. Threat of New Entrants (Can new competitors easily enter?)
The risk that new competitors will enter the market and capture share.
High Threat When:
Low barriers to entry (capital, expertise, licensing)
Attractive industry margins and growth
Incumbents are vulnerable or complacent
Distribution or channel access is available
Economies of scale are limited
Network effects are weak or absent
Regulation is permissive
New technologies enable disruption
Low Threat When:
High barriers to entry (capital, IP, expertise, relationships)
