Conducted by the Society for Human Resource Management, the 2007 Change Management Survey asked upper-level human resource (HR) professionals in the United States about their experiences with major organizational changes. With HR professionals reporting the types of major changes their organizations planned or implemented, the ways that HR had been involved in the transition, how employees received communications and training, and the outcomes achieved as a result of HR involvement, this report presents a thorough analysis of the survey results and examines the differences between organizations' change management practices according to staff size and employment sector.
