Michael Porter's (1980) strategic typology is presented. Some critical analyses, complements and refinements advanced by many authors, especially Mintzberg (1988), are discussed. Some extensions proposed by Miller and Dess (1993) and Chrisman, Hofer and Boulton (1988) are also shown. The Resource-Based View is put forward as a counterpoint. The evolution of Porter's (1980) line of thought through the years - since 1980 until 1996 - is also discussed, which makes it possible to understand the way Porter (1980) has been detailing and redefining his focus - from industry structure up to the system of activities.
