ESTRATÉGIAS GENÉRICAS: UM ESTUDO EVOLUTIVO E COMPARATIVO DE TRÊS VISÕES.

This study analyses visions of three of the most renowned authors regarding generic strategies, making a comparison among those visions along the time. To perform such comparison, two distinct works of each author were selected and then it is pointed out how changes showed up from one moment to another. The selected authors are Ansoff, Miles et al. and Porter, all responsible for three of the most spread typologies for generic strategies. From a chronological point of view, these typologies have been originally proposed between 1965 and 1980 and revisited between 1985 and 1988. Despite time passed from then until today, these typologies are still fully adequate and completely applicable to organizations' present reality. Contributions of this study reside on detailed presentation of each typology's major characteristics, due to detailed and judicious bibliography revision. [ABSTRACT FROM AUTHOR]
