Recovering From A Stalled Change Initiative: A Case Of Correcting Implementation Mistakes, Ellen L. Dorey
Theses and Dissertations
Amid an age of increasing technology, innovation, and global business competition, there is no question that the pace organizational changes are introduced will increase, as well. With this pace of change, organizational leaders might find themselves short on the time and resources necessary to properly create readiness by utilizing implementation strategies. Frequently, a change initiative that is not introduced properly will meet resistance within the organization. When strong resistance is encountered, the initiative is often abandoned and replaced with some other effort. However, in some situations, the initiative can not be abandoned and implementation must continue. This research effort sought …
