Effects of Planning Aids and Presentation Media on Performance and Affective Responses in Strategic Decision-Making
研究比较了辩证探究系统、魔鬼代言人和传统专家法三种决策辅助工具，以及书面和录像两种呈现媒介，对战略决策中方案生成、最终建议和满意度的影响。
The Dialectical Inquiry System (DIS) and the Devil's Advocate (DA) have been recommended as strategic decision-making aids and as improvements on the traditional expert (E) approach in which strategic decisions are based on preliminary analyses and proposals by staff experts. Previous research on the effects of the DIS and DA has produced conflicting results. In the present study, subjects produced alternative strategies and recommendations for a company described in a case. They were given the E, DA, or DIS treatment either in written form or via videotape. In addition, some were assigned to a control (C) group and received no planning assistance. The results showed that the written DA, the videotape DI, and the videotape E treatment caused subjects to generate fewer functional area alternatives than the C subjects. Further, the subjects receiving the written DA generated more strategic alternatives than those receiving the written DIS or E. The DA also reduced the effects of an “expert report” on subjects' final recommendations while the DIS did not. Subjects given the DA and DIS reported greater satisfaction with the process than those given the E.
