Strategy involves responding to environmental challenges to compete successfully in the market. It includes a plan and long-term vision. An effective mission statement includes the permanent benefit to stakeholders, the means to achieve it, target audiences, and core values. It should define the company's expertise, promise, and competitive position. Building a strategy requires considering both the external environment including markets, competition, and technology, as well as internal strengths, weaknesses, and structure.
