Communication is repeatedly described in the literature as a success factor for the effectiveness of change management processes. However, the questions of when and how communication should be most effectively implemented and designed during the phases of change often remain unanswered. Xira Tröller presents a well-stocked toolkit of instruments and methods for managing change processes within an organization's internal communication, structured around the phases of 'unfreeze', 'move', and 'freeze' as described by Lewin. Her scientifically grounded yet practical insights are particularly beneficial for professionals and leaders in social work.
