Porter's Five Forces Analyzer

Porter's Five Forces is a framework developed by Michael Porter to analyze the competitive intensity and attractiveness of an industry. The five forces are: Competitive Rivalry (existing competitors), Supplier Power (bargaining power of suppliers), Buyer Power (bargaining power of customers), Threat of Substitution (availability of alternative products), and Threat of New Entry (ease of entering the market). Together, these forces determine the profit potential of an industry.

Rate each force from 1 (very low/weak) to 5 (very high/strong). A rating of 1 means the force has minimal impact on your industry profitability, while 5 means it significantly threatens profits. For example, if buyers have many alternatives and can easily switch, Buyer Power would rate 4-5. If barriers to entry are high (capital, regulations, patents), Threat of New Entry might rate 1-2. Be honest in your assessment for accurate strategic insights.

High scores (4-5) on any force indicate significant competitive pressure that can erode industry profitability. A high overall score suggests a challenging competitive environment where maintaining margins is difficult. Low scores (1-2) suggest favorable conditions. The most profitable industries typically have low scores across all five forces. Your strategy should focus on mitigating the strongest forces while leveraging areas where forces are weak.

Conduct a Five Forces analysis annually as part of strategic planning, and additionally whenever significant industry changes occur such as new regulations, major competitor moves, technological disruptions, or market shifts. Industries with rapid change (tech, digital) should be analyzed more frequently. The framework helps you stay proactive rather than reactive to competitive dynamics.
