Grand strategies involve long-term plans chosen from available alternatives to overcome weaknesses, build strengths, avoid threats, and seize opportunities. They are classified as stability strategies, which maintain the status quo; expansion/growth strategies, which achieve higher objectives; and retrenchment strategies, which improve performance through contraction. Combination strategies blend elements of stability, growth, and retrenchment. Grand strategies are selected by top managers and used in strategic business planning to analyze internal and external environments.
