Job Change: A Naturally Occurring Field Experiment
在三家研发机构开展为期一年的自然现场实验，发现工作变动（晋升或调岗）的员工在绩效、创新、满意度上提升更大，角色模糊减少更多，且工作特征（多样性、自主性）和角色要求（整合、跨界活动）增加更显著。
A naturally occurring field experiment of job change was conducted over a one-year period in three applied research and development organizations. The experimental group (n = 42) were those employees who had been promoted or assigned to a different job. Employees who had maintained the same job made up the nonequivalent control group (n = 166). Standardized change score analysis showed the job change group to have greater increases in performance, innovativeness, and job satisfaction, as well as a greater reduction in role ambiguity when compared to the nonequivalent control group. In addition, the job change group reported greater increases in the job characteristics of variety and task autonomy, as well as in the role requirements of integration and boundary-spanning activities. The importance of the results and the role of field experimentation are discussed.
