This document provides an overview of strategic management concepts including defining strategy, classifying strategy, and tests of a winning strategy. It discusses Mintzberg's five-fold definition of strategy as a plan, pattern, position, ploy, and perspective. Strategy can be classified based on its generic basis, levels in an organization, corporate direction, product/market focus, intensity of competition, and intention versus realization. Tests of a winning strategy ensure good fit with the external environment and internal resources, provide competitive advantage, improve performance, have coherence between values and actions, are distinctive from competitors, and are sustainable long-term.
