"This book is a doorway into generative, strengths-inspired and solutions-focused change. It gives leaders the gift of new eyes and teaches how humility might just be a leader's greatest strength. It brings the joy of high quality connections back into the field of organization development. And it reminds us that we can create conditions - the evidence base is there — to confirm our deepest conviction: that human beings are good. Read this wonderful book carefully."—David Cooperrider, Weatherhead School of Management, Case Western Reserve University"We need to develop work organizations in which people thrive and find positive meaning in life rather than being impoverished and exhausted by organizational change. This book offers a profoundly important guide to how we can create such organizations, providing the theoretical rationale, evidence and practical steps necessary to achieve transformational change. Every manager and leader of every organization should not only read it but immediately put it into practice."—Michael West, Lancaster University Management School"Sarah Lewis is one of those rare management writers able to combine academic research with practical relevance. In Positive Psychology and Change she offers a fresh, evidence-based rethinking of how large group organizational change methods work and many practical suggestions for how to use them successfully."—Gervase R.
