In every change process, constructive communication and psychological change intelligence play a crucial role. The success or failure of changes depends not so much on sophisticated business or technical tools, formats, and methodologies, but rather on the psychological competence of the individuals responsible for the process. Changes can create uncertainty and may provoke resistance. Therefore, those in charge must also possess courage and assertiveness. Time and again, practice shows that perceptual accuracy, an understanding of fundamental psychological mechanisms, constructive communication, and a touch of charisma create the greatest opportunities for influence and design. This book demonstrates how to acquire and effectively utilize such skills.
