This collection of case studies captures a range of issues faced by institutions in transformation in the social development sector, as they evolve and mature. Leadership transitions, gender issues at the workplace and the challenges of large systems owning up to their development agenda are some of the themes explored.The case studies included in the book comprise narrative reports on the change processes, reflective essays by the consultants and peer reviews. Practitioners have clearly identified the gaps between their initial assumptions and their actual experiences, providing interesting material for others to learn from. The voice and language of the narrator is retained, adding to the authenticity of the compilation. An overview of the tools used offers a ready guide to Organisation Development (OD) practitioners.This book is an invaluable addition to the available knowledge base both in terms of its content and the process that has been used to build the case studies. It will be of interest to consultants, students and teachers of OD and Organisational Behaviour. Human Resource Management Divisions in organisations will also find it useful.
