Technical Progress and Performance

  • Louis A. Girifalco


There is no doubt that the long-range trend of technological change has been toward ever-increasing complexity, sophistication, and greater technical performance. The analysis of technological change requires that some carefully defined measures be constructed that will permit the comparison of the state of technology at different times. Here, two different kinds of such measures will be considered. The first refers to the actual performance capabilities of a device, process, or system, while the second refers to the efficiency with which a technological system is utilized in practice.
