The New economy has brought great business opportunities besides great challenges. Not since the Industrial Revolution has managing with change been so urgent a matter. Indeed, the Information Age has accelerated the pace of market and business changes to the point where some firms have set up "change departments" whose job is to constantly look for opportunities to change the firm and make it more productive.

Most firms have accepted the fact that they must make major changes. To remain competitive, companies recognize that they need to be in a constant process of changing themselves. This change is accompanied by the need to be willing to take risks in management style. Managers with such spirit have called themselves "change agents".

Despite some remarkable successes, however, introducing managing change has not been a simple matter. Firms have tried to introduce change to achieve its attendant efficiencies (节省幵支）through new technologies, restructuring, or outsourcing. Yet, this has cost a great deal of time and money, but often led to at best mixed results: approximately 75% of all change activities failed.    、

The reason for most of these failures is that change often lacks a central focus. Managers become confused by all different and sometimes conflicting advice they receive about change management. The result is a loss of central focus and disorganized policies. To improve their chances of success, it is extremely important that managers should understand the nature and process of the whole company's change and its challenges much better.
