Three Components of Perceived Environmental Uncertainty: An Exploratory Analysis of the Effects of Aggregation
118名项目经理填写了Duncan的问卷，因子分析发现感知环境不确定性包含状态、影响和反应三个维度，且这些维度与绩效的关系不同。
Duncan's 1972 instrument was completed by 118 Project Managers to investigate perceived environmental uncertainty (PEU). Factor analysis indicates significant loadings on three factors corresponding to Milliken 's (1987) state, effect, and response uncertainty. Measures of project manager performance were found to be differentially associ-ated with total PEU and its disaggregated components of state, effect, and response uncertainty.
