I first saw the balanced scorecard in the mid-1980's and even used one for about a year. I did not find it a useful tool and eventually abandoned it. After hearing Deming I lost interest. It was too focused on targets and has a tendency to be used to punish or reward people for meeting them.
I have "known of" the balanced scorecard concept for maybe 10 years, but only through schoolwork and reading. I have never seen it implemented effectively, and the few times I have heard it discussed at various workplaces it seemed the implementation had little relationship to what I had learned earlier. One constant, though, is that information rarely, if ever, filtered down to the line worker level.
