No business concept was more important to America's economic revival in the 1990s than reengineering, introduced to the world in Michael Hammer and James Champy's Reengineering the Corporation. Already a classic, this international best seller describes how the radical redesign of a company's processes, organization, and culture can achieve a quantum leap in performance.But if you think that reengineering once was enough, think again. More changes, more challenges are coming in the twenty-first century. Now Hammer and Champy have updated and revised their milestone work for the New Economy they helped to create, promising to help corporations save hundreds of millions of dollars more, raise their customer satisfaction still higher, and grow ever more nimble in the years to come.
