This circle-spoke diagram sample shows the Porter five forces model. It was designed on the base of the Wikimedia Commons file: Modelo Porter.png. [commons.wikimedia.org/ wiki/ File:Modelo_ Porter.png]
"Porter's five forces analysis is a framework that attempts to analyze the level of competition within an industry and business strategy development. It draws upon industrial organization (IO) economics to derive five forces that determine the competitive intensity and therefore attractiveness of an Industry. Attractiveness in this context refers to the overall industry profitability. An "unattractive" industry is one in which the combination of these five forces acts to drive down overall profitability. A very unattractive industry would be one approaching "pure competition", in which available profits for all firms are driven to normal profit. This analysis is associated with its principal innovator Michael E. Porter of Harvard University. ...
Porter's five forces include – three forces from 'horizontal' competition: the threat of substitute products or services, the threat of established rivals, and the threat of new entrants; and two forces from 'vertical' competition: the bargaining power of suppliers and the bargaining power of customers."
