Business Strategy Tool

The tool was created by Harvard Business School professor Michael Porter, to analyze an industry's attractiveness and likely profitability.

Since its publication in 1979, it has become one of the most popular and highly regarded business strategy tools.

Porter recognized that organizations likely keep a close watch on their rivals, but he encouraged them to look beyond the actions of their competitors and examine what other factors could impact the business environment.

He identified five forces that make up the competitive environment, and which can erode your profitability.
