What problem does it solve? Evaluating whether an industry or market is structurally attractive requires more than gut feeling. This Skill applies Porter's Five Forces framework to systematically assess competitive rivalry, supplier power, buyer power, threat of substitutes, and threat of new entrants, so strategic decisions rest on a named method rather than intuition. ## Core Features & Use Cases - Five-Force Assessment: Rates each force (High, Medium, Low) with detailed criteria for when each force is strong or weak. - Strategic Implications: Provides concrete strategic responses for each force, such as building switching costs, diversifying suppliers, or raising entry barriers. - Attractiveness Rating: Synthesizes the five forces into an overall industry attractiveness judgment and prioritizes the 2-3 most critical forces. - Use Case: A product manager evaluating entry into a new market segment runs the analysis to discover that buyer power is high due to concentrated enterprise customers, then designs lock-in and differentiation initiatives before committing resources. ## Quick Start Run a Porter's Five Forces analysis on the B2B SaaS project management software market and tell me which forces matter most.
