Using Single Respondents in Strategy Research
这篇短文指出，许多实证研究仅依赖CEO或高管团队中的单一受访者来推断企业战略维度，但基于对76家企业多位受访者的调查发现，同一高管团队内部回答差异较大（用Cronbach alpha衡量），因此这种方法可能不可靠。
A survey of empirical papers has revealed a number of studies that have used single respondents, usually the CEO or a top management team member, to make inferences about certain strategic dimensions of their business. In this note, we highlight some of the problems in using this approach. We base our comments on a study of 76 businesses where multiple respondents were accessed. We conclude that, because of often wide variations in responses between members of the same top team (measured by Cronbach alpha), the use of single respondents in this type of strategy research is probably unreliable.
