This research paper focused on the concept of change management from two perspectives. One, where Nokia failed to implement change effectively, and two where Samsung did everything right while implementing change. This research identified how failing to understand and implement just three steps of Kotter’s change management can cause catastrophic failure that happened with Nokia. Therefore, from this research paper, it can be conclude that if implemented properly change management can improve performance of an organization such as Samsung. On the other hand, if it is not implemented properly, it can hamper performance of an organization such as Nokia.
