The strongest objection to measurement of knowledge worker productivity is inaccuracy of the results. This productivity measurement is very valuable as a dynamic gauge, not a static measure. What this means is that since these inaccuracies are consistent, the dynamic measure will be an accurate indicator of the relative change. However, he adhered to hours worked (or man-hours as it was termed in the 70s) as a measure of labor input. Kuznets showed that the contribution of the factor inputs per capita was a minor fraction of the growth rate of per capita product . According to his estimates, the contribution of increases in capital input per capita over this extensive period was negative. You could be hardworking enough but at the end of the day, productivity is counted on how many completed tasks are of good quality. If you do your job right, your overall productivity and reliability is virtually increased. Your boss would surely take notice and so there would be better opportunities coming your way. Somebody finally suggested reversing everything: bring the materials to the top floor, do the sub-assembly at the second floor and the final assembly in the first floor. It had a big positive effect on productivity. They were able to produce more with the same number of workers. Mr. Triplett did not comment much on the change of multifactor productivity because of KLEMS. Time diaries, estimates, work samplings and direct observations are some of the tools employed by Anthony (1984). The gathered data are analyzed by a computer, and reviewed to eliminate insignificant items. All in all, each of these other techniques of productivity measurements has their good points worth taking a look. Writers have related the preoccupation with efficiency to the development of a measurement cult that precludes many of the less quantifiable but essential ingredient of a successful enterprise. Consider the value of a highly efficient production of un-salable goods or perhaps a person pursuing his own target and refusing to cooperate with colleagues who are falling behind.
