There are multiple levels of strategy needed for companies. Corporate strategy covers objectives and coordination across business units (SBUs). SBU strategies provide objectives and coordination for each business unit to contribute to corporate goals. Functional strategies deal with objectives and coordination within specific functions like marketing, sales, and distribution to support SBUs and corporate strategy. Strategists at different levels are involved in strategic management, including the board of directors, CEO, senior management, SBU executives, corporate planning staff, consultants, and entrepreneurs.
