Daniela Dujmic-Erbe has developed a step-by-step guide and a unique all-in-one tool for efficient communication: the Communication Cube. The workbook reveals how to use this three-dimensional checklist to communicate in a way that achieves personal goals while also considering those of the other party. It describes the use of the Communication Cube in training, (self-)coaching, and conflict conversations. Detailed exercise descriptions, a seminar plan, and numerous illustrations complement the theoretical background knowledge. The Communication Cube is suitable for nearly every conversation situation in both professional and private settings and is a valuable companion for anyone looking to improve their communication skills or support communication processes.
