Understanding Change: theory, implementation and success argues that strategic change in the new millennium will be geared increasingly to achieving sustainable high performance, rather than just short-term gains. Most theorists now agree that the real challenge of change lies in gaining employees" willingness to commit to the change effort. Change leaders at every level need to be able to understand the elements at work in any change process, and to use judgement about the style of leadership required to give the change effort the best chance of success. The book provides an overview of change and organizational theory, leading in particular to the author"s definition of the "input" elements of the high performance organisation, based on extensive research into UK and international organisations. It also contains a section looking at the management of change, with case studies illustrating approaches to managing change which are conducive to achieving sustainable high performance.
