In order to survive every organization must learn to cope with change. When change is proactive and planned, the likelihood of successful change is much greater. The more complex the change is, the greater the difficulty of implementing the change, e.g. innovating for sustainability, implementing a new strategic direction, or addressing the risks and opportunities of climate change. Organizational Change Management is a field that was developed to lead organizations through the change process by providing a roadmap to plan, initiate and stabilize change. This book illustrates how to approach organizational change by providing a process for developing a change strategy, critical success factors and levers for successful change. Special considerations for implementing organizational change as it relates to sustainability are described.
