Core: A framework for understanding the competitive environment and determining strategic positioning by analyzing the structure of an entire industry.

Characteristics:
(Profitability and competitive intensity) Analyzes an industry’s profitability and competitive intensity.
(Five competitive forces) Systematically analyzes five forces: barriers to entry, supplier/buyer bargaining power, threat of substitutes, and existing rivalry.
