Researchers have advocated various perspectives on the relationship between strategic consistency and organizational performance. This inconclusive debate has created an inadequate theoretical foundation in strategic consistency literature. Therefore, the present study uses strategic planning, strategic change, upper echelons theory, and other literature as the theoretical foundation to empirically examine the moderating roles of organizational slack, environmental dynamism, and top management team attributes in the relationship between strategic consistency and organizational performance. Using 439 electronics companies in the Taiwanese stock market as sample data, the empirical results show that organizational slack, environmental dynamism, top management team tenure, and top management team tenure heterogeneity moderate the relationship between strategic consistency and organizational performance.
