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?

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)
