Technical Manual for the AIMs Survey
In spite of the need for high performance, research shows
that there are still major differences in productivity among employees. In
a recent book on selection, Adrian Furnham wrote that variance in
productivity across workers averages about two to one: that is, good
workers produce about twice the output of poor workers. In the weaving
industry, for example, good workers produce 130 picks per minute compared
to poor workers’ rate of 62 picks per minute (the same ratio was found
among hosiery workers, knitting machine operators and taxi drivers). As
the work becomes more complex, the productivity ratio becomes even higher,
so that a good physicist produces much more than twice the output of a
poor one (Furnham, 1992).
