Change is a powerful force, but one that must be directed if it is to have a positive and calculated outcome. It can be shaped according to the needs of an organisation to grow or contract, respond to competition or threat, or simply to keep pace with the world around it. It is widely understood by leaders and managers that only effective project management has the potential to deliver the transformation they seek. However, many projects have failed to deliver the outcomes that their sponsors anticipated. Too many have produced apps, buildings, processes, products and services that remain on the shelf, unadopted, and a costly reminder that projects are vehicles that can just as easily deliver failure as success. The revised and expanded third edition of this much-admired guide explains the principles and techniques of change and project management. With its clear, structured approach it is an invaluable handbook for helping leaders and managers to be sufficiently informed, equipped and confident to use projects to deliver change, and to realise its benefits.
