Abstract: | Several approaches have been used to explore environmental dynamism as a contingent predictor of the relationship between rational‐comprehensive strategic decision‐making and firm‐level performance. At the decision level of analysis, however, small sample sizes, low statistical power, and statistical dependence have plagued the research. Through the use of a simulated decision‐making environment and multilevel analysis, this study examined 400 decisions from 54 executive teams. Consistent with much of the existing firm‐level research, the results indicated that environmental dynamism may moderate the relationship between rational‐comprehensive decision making and decision quality. Surprisingly, the form of the relationship differed from much of the firm‐level research. Copyright © 2003 John Wiley & Sons, Ltd. |
