Hello from Porterfan1.
Porterfan1 is an expert in strategic planning methodologies, industry classification schemes, global market research, and research conducted by eCompetitors Inc. Porterfan1 has been using Michael E. Porter's methodologies for the last 23 years.
ECOMPETITORS has just spent seven years building the world's first global industry classification system at the line-of-business level, the level where Michael E. Porter defines the term industry. ECOMPETITORS covers the top 10,000 global industries.
NAICS, the North American Industry Classification System, likely has the closest taxonomy; but the ECOMPETITORS' classification system is about 7 times longer in terms of "industries" - plus ECOMPETITORS is global, and the amount and type of information covered is much richer and deeper because it leverages the ideas of Michael E. Porter. NAICS is a derivative work product of SIC codes which were developed in the U.S. in the 1930's. The United Nations effort in this area is global, but its classification system is more at the industry sector and industry group level - not at the Michael Porter level for a five forces analysis.
Porterfan1 believes the ECOMPETITORS article should be a "Featured article in Wikipedia" because it is relevant to anyone interested in the global economy or any industry which define the global economy
