Five Forces Analysis

Porter's Five Forces, developed by Michael Porter, is a framework for analyzing the competitive intensity and attractiveness of an industry — assessing five forces that together determine how much profit potential an industry structurally allows, independent of any single company's own strategy.

The five forces

• Competitive rivalry — the intensity of competition among existing players (number of competitors, industry growth rate, differentiation level).
• Threat of new entrants — how easily new competitors can enter the market (barriers to entry: capital requirements, regulation, brand loyalty, Strategic Scale Effects).
• Bargaining power of suppliers — how much leverage suppliers have to raise prices or reduce quality/availability.
• Bargaining power of buyers — how much leverage customers have to demand lower prices or better terms.
• Threat of substitutes — how easily customers can switch to a different product or service that meets the same underlying need.

Why analyze the industry, not just the company

Unlike SWOT Analysis (which examines a specific organization) or PESTLE Analysis (which examines the broad macro-environment), Five Forces specifically examines the structure of the industry itself — a useful complement, since even an excellent company can struggle in a structurally unattractive industry (high rivalry, strong buyer power, low barriers to entry), while a mediocre company can thrive in a structurally favorable one.

Using the analysis

A high-scoring force (strong pressure) generally signals lower achievable industry profitability; the analysis helps identify which specific force is the biggest constraint on an industry's attractiveness, and can inform strategic moves that specifically weaken that force (e.g. building Strategic Moat Effects against new entrants, or diversifying suppliers to reduce their bargaining power).

Common pitfalls

• Analyzing the company instead of the industry — Five Forces is explicitly about industry structure; conflating it with a company-specific analysis (better suited to SWOT Analysis) misses its actual purpose.
• Treating the five forces as equally important in every industry — their relative weight varies significantly by industry; a strategic response should target whichever force is actually the binding constraint.
• Doing a one-time analysis in a fast-changing industry — industry structure can shift meaningfully (regulatory change, new technology enabling new entrants); the analysis benefits from periodic review, not a single static assessment.
