Input Uncertainty and Organizational Coordination in Hospital Emergency Units
基于美国六个州30个急诊单元的数据，研究了输入不确定性如何影响协调方式与组织有效性的关系，发现低不确定性下程序化协调更有效，高不确定性下非程序化协调更有效。
The relationships among input uncertainty, means of coordination, and criteria of the organizational effectiveness of hospital emergency units were explored using data from 30 emergency units in six midwestern states. Input uncertainty generally was not associated with the use of various means of coordination. However, input uncertainty affected relationships between the means of coordination and the effectiveness criteria. Specifically, programmed means of coordination made a greater contribution to organizational effectiveness under conditions of low uncertainty than under conditions of high uncertainty. Conversely, nonprogrammed means of coordination made a greater contribution to organizational effectiveness when uncertainty was high than when it was low. Findings were interpreted and suggestions were advanced as to how emergency units might best solve their coordination problems under varying conditions of uncertainty.
