Change Management is a crucial process for gaining the competitive advantage that is the goal of many organisations. This 4th edition of Organisational Change: Development and Transformation has been comprehensively revised to fully explain change management from the perspectives of organisational development and organisational transformation. Restructured into 12 chapters under 6 parts, the text opens with an explanation of the environment of change faced by organisations today. It then deals with managing organisational development, being 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 organisation 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 4e provides 11 new local and international case studies and a suite of online cases supported by a case matrix.
