Book excerpt: Change Management is a crucial process for gaining the competitive advantage that is the goal of many organisations. Leaders and change agents are often faced with conflicting challenges of motivating and understanding increasingly diverse workforces, accounting to stakeholders and planning for the future in a chaotic environment. Comprising 12 chapters in 6 parts, the text opens with an explanation of the environment of change faced by organisations today. It then deals with managing organisational development, which is a planned process of change which is often subject to the incursions of organisational transformation, a more dramatic and unpredictable type of change. With the field of organisational change continuing to evolve, especially in an international context, future directions of change management are also discussed. Finally, to emphasise the relationship between theory to practice, Organisational Change: Development and Transformation 6e provides 10 local and international case studies and a suite of online cases supported by a case matrix. Case studies, exercises and support material present the challenges of change management in a real-life manner - examining issues from a variety of viewpoints.
