         Lean or Mean: The MIT Model

         and Lean Production at Mazda




                               Steve  Babson



            MIT's International Motor Vehicle Project has promoted the Japa-
        nese Model of lean production as a cure-all for American automakers.
        According to their best-selling book, The Machine That Changed the
        World, a key attribute of lean production that makes it more efficient than
        mass production is that it emancipates workers and gives full play to their
        creativity. Survey results drawn from 2,400 workers at the Mazda assem-
        bly plant in Flat Rock, Michigan, provide an opportunity to test these
        claims. The results suggest that the emancipative potential of lean pro-
        duction has been misstated in at least two respects. First, in the eyes of
        American workers, when the production system is lean, many see it as
        mean. Second, union intervention can redefine the meaning of lean
        production by challenging the system's potential for unilateral manage-
        ment control. Specifying the future of lean production requires a detailed
        indication of how power is distributed and conflict regulated, particularly
        as these relate to union and nonunion environments.





      Is Japan's  system  of  lean production   the cure-all for American
automakers?  James  Womack, Daniel Jones, and Daniel Roos, senior manag-
ers at MIT's International Motor Vehicle  Project, say yes. According to their
best-selling book, The Machine   That Changed   the World,  a key attribute of
lean production  that makes  it more efficient than mass production  is that it
emancipates  workers   and gives full play to their creativity.
      Womack et al.   say Japanese  auto  plants are lean because  manage-
ment  has slashed inventories, pared support staff, and replaced cumbersome
factory hierarchies with self-directed work teams. By  rotating jobs and shar-
