SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Product managers and strategists often lack a structured way to evaluate whether an industry or market is worth entering, and which competitive forces will determine profitability. This Skill applies Porter's Five Forces framework to systematically assess rivalry, supplier power, buyer power, substitutes, and new entrants. ## Core Features & Use Cases - Five Forces Assessment: Evaluates competitive rivalry, supplier bargaining power, buyer bargaining power, threat of substitutes, and threat of new entrants with detailed strong/weak indicators for each force. - Industry Attractiveness Rating: Rates each force as high, medium, or low and derives an overall industry attractiveness judgment. - Strategic Recommendations: Identifies the 2-3 most critical forces and produces strategic responses, positioning opportunities, and matching initiatives. - Use Case: Before entering the electric vehicle charging market, run this analysis to determine that buyer power is high and entry barriers are low, then design a differentiation strategy around network lock-in. ## Quick Start Ask the AI to run a Porter's Five Forces analysis on your target industry, providing the market definition, key competitors, suppliers, and customers.

FAQPage Schema
How do I run a Porter's Five Forces analysis on an industry?

Provide the industry definition, existing competitors, supplier and customer landscape, and potential substitutes or entrants. The analysis evaluates each of the five forces as high, medium, or low, then derives an overall industry attractiveness rating and strategic responses.

What inputs are needed for a Five Forces analysis?

You need the industry or market definition, existing competitors and their positioning, the supplier and customer landscape, potential substitutes and new entrants, and specifics about the product or service being analyzed.

Can Porter's Five Forces be combined with SWOT or PESTLE analysis?

Yes, the Skill explicitly recommends combining Five Forces with SWOT and PESTLE for a complete strategic picture. Five Forces covers industry structure while SWOT and PESTLE address internal capabilities and macro-environmental factors.

When should I not use Porter's Five Forces analysis?

Avoid relying on it alone for fast-changing markets where industry boundaries blur, since the framework assumes a defined industry structure. It also does not account for regulation shifts or platform ecosystem dynamics without supplementary frameworks.

How does the analysis determine if an industry is attractive?

An industry is attractive when rivalry is mild, suppliers and buyers are weak, substitutes are few, and entry barriers are high. It is unattractive when the opposite conditions hold, and mixed forces require strategic differentiation.
