--- name: porters-five-forces description: "Analyze industry competitive dynamics using Porter's Five Forces framework. Use when entering a new market, assessing industry attractiveness, or understanding competitive positioning." --- # Porter's Five Forces Analysis ## Metadata - **Name**: porters-five-forces - **Description**: Industry competitive analysis framework - **Triggers**: five forces, competitive analysis, industry analysis, porter, market structure ## Instructions You are a strategic analyst conducting Porter's Five Forces analysis for $ARGUMENTS. Your task is to systematically analyze the five competitive forces that shape industry profitability. ## Framework ### Force 1: Rivalry Among Existing Competitors **Key questions:** - How many competitors? How balanced are they? - Industry growth rate (slow growth = more rivalry) - Fixed costs vs variable costs ratio - Product differentiation level - Exit barriers height **Assess:** Low / Medium / High ### Force 2: Threat of New Entrants **Barriers to entry:** - Economies of scale - Product differentiation / brand identity - Capital requirements - Switching costs for customers - Access to distribution channels - Government policy / regulation - Expected retaliation from incumbents **Assess:** Low / Medium / High ### Force 3: Bargaining Power of Suppliers **Supplier power increases when:** - Few suppliers, many buyers - No substitute inputs - Industry is not important customer - Supplier products are differentiated - Switching costs are high - Threat of forward integration **Assess:** Low / Medium / High ### Force 4: Bargaining Power of Buyers **Buyer power increases when:** - Few buyers, many sellers - Products are undifferentiated - Switching costs are low - Buyers pose credible backward integration threat - Product is important to buyer's costs - Buyers have full information **Assess:** Low / Medium / High ### Force 5: Threat of Substitutes **Substitute threat increases when:** - Price-performance of substitutes is attractive - Switching costs to substitutes are low - Buyer propensity to substitute is high **Assess:** Low / Medium / High ## Output Process 1. **Define the industry precisely** - boundaries matter 2. **List key players** in each category (competitors, suppliers, buyers, potential entrants, substitutes) 3. **Analyze each force** with supporting evidence 4. **Rate force intensity** (Low/Medium/High) 5. **Summarize industry attractiveness** - Overall profitability potential 6. **Identify strategic implications** - How should we position? ## Output Format ``` ## Porter's Five Forces: [Industry] ### Industry Definition [Clear boundary statement] ### 1. Rivalry: [Low/Medium/High] - Evidence point 1 - Evidence point 2 - Key driver: [main factor] ### 2. New Entrants: [Low/Medium/High] - Evidence point 1 - Evidence point 2 - Key barrier: [main factor] ### 3. Supplier Power: [Low/Medium/High] - Evidence point 1 - Evidence point 2 - Key driver: [main factor] ### 4. Buyer Power: [Low/Medium/High] - Evidence point 1 - Evidence point 2 - Key driver: [main factor] ### 5. Substitutes: [Low/Medium/High] - Evidence point 1 - Evidence point 2 - Key threat: [main factor] ### Summary | Force | Intensity | Trend | |-------|-----------|-------| | Rivalry | X | ↑/→/↓ | | New Entrants | X | ↑/→/↓ | | Supplier Power | X | ↑/→/↓ | | Buyer Power | X | ↑/→/↓ | | Substitutes | X | ↑/→/↓ | ### Industry Attractiveness: [Low/Medium/High] ### Strategic Implications 1. [Implication 1] 2. [Implication 2] 3. [Implication 3] ``` ## Tips - Regulation can be a "sixth force" - mention if relevant - Model is static - note dynamic trends - Use quantitative evidence where possible (CAGR, HHI, margin benchmarks) - Consider geographic scope (local vs global forces differ)
