Strategic management involves three main stages: strategy formulation, strategy implementation, and strategy evaluation. In strategy formulation, companies determine their vision, mission, external opportunities and threats, internal strengths and weaknesses, long-term objectives, and alternative strategies. In strategy implementation, companies develop annual objectives, policies, and allocate resources to achieve the strategic plan. In strategy evaluation, companies conduct internal and external reviews to measure performance and make corrective actions. Effective strategic management provides benefits such as enhanced awareness of threats and improved understanding of competitors' strategies.
