Porter's Five Forces: Industry Analysis Framework
Porter's Five Forces is an industry analysis framework that examines five competitive forces to determine industry attractiveness and profitability potential.
What Is It?
Porter's Five Forces, introduced by Harvard Business School professor Michael Porter in 1979, is one of the most influential frameworks in strategic management. It analyzes the competitive dynamics that shape every industry.
The five forces are: Threat of New Entrants (how easily can competitors enter?), Bargaining Power of Suppliers (can suppliers dictate terms?), Bargaining Power of Buyers (can customers demand lower prices?), Threat of Substitutes (what alternatives exist?), and Competitive Rivalry (how intense is current competition?).
Strong forces reduce industry profitability; weak forces increase it. The framework helps identify attractive industries and informs positioning strategy. It complements broader tools like SWOT Analysis and PEST Analysis.

Comparison with Related Frameworks
Five Forces vs SWOT
SWOT is broader and quicker. Five Forces provides deeper competitive insight. Use SWOT first, then Five Forces for rigorous industry analysis.
Five Forces vs Blue Ocean
Blue Ocean Strategy seeks to escape competitive forces entirely. Five Forces analyzes existing competition. Complementary perspectives.
