An Empirical Study of Flexibility in Manufacturing

1. We did not select these companies randomly; with one exception, all are large electronics manufacturers that are members of programs at the Massachusetts Institute of Technology (Leaders for Manufacturing Program, International Center for Research on the Management of Technology, and Industrial Liaison Program). We gathered data in questionnaires, plant visits, and in-person or telephone interviews. Overall, the authors visited sixteen plants and conducted phone interviews with all of them. For further information on the methodology, see:

10. Fiegenbaum and Karnani seem to use these concepts interchangeably. Stigler and Marschak and Nelson give theoretical support to our definition. See:

11. This is consistent with Jaikumar’s observations regarding American flexible manufacturing systems. See:

Jaikumar (1986).
