The last twenty-five years of the twentieth century was a period of extraordinary change in organizations and the economies of the developed world. This continues today. Such has been the scale and momentum of events that, for some analysts, the only comparable periods are the early part of the twentieth century in which the shift to mass production and large-scale organization was accomplished, or the industrial revolution itself a hundred years earlier. Researchers in Europe and the USA, in particular, have been studying change in work and organizations, but there has been little attempt to systematize and draw together the results of their work. So far, the emphasis amongst writers on organizations considering the problem of contemporary change has been on ways of conceptualizing events, rather than also considering evidence. But, what has actually happened? How much of the flux of events is real change, and how much mere change in emphasis in which apparent change is overlaying organizational continuity? How far are changes in particular events and sectors connected, and is an overall understanding of complex processes possible?.
