The modern world is VUCA. It is unpredictable, uncertain, complex, and ambiguous. The improvisational talent of everyone is required. Leaders and employees must learn in real-time from processes of change, manage crises, and be prepared for the unknown at all times. For employees who are used to working in a stable, secure, simple, and clear SSEE world, this is an unfamiliar challenge. The book illustrates how the both-and principle helps restore the daily balance between the demands of the new VUCA world and the good old SSEE world, thereby preventing stress, overwhelm, conflicts, and psychological burdens. Promoting resilience is primarily about fostering culture. Resilience expert Ella Gabriele Amann and long-time pharmaceutical manager Frank Alkenbrecher advocate for a paradigm shift in leadership style.
