Following the brief diversion around my ankle, now the third and last in this little series. A very simple summary.
Based not only on the personal experience of many years of management, but also the evidence of independent controlled studies:
Statistical Fact 1: After positive rewards for good results, subsequent performance tends to deteriorate.
Statistical Fact 2: After admonishment for poor results, subsequent performance tends to improve.
Statistical Fact 3: Positive rewards tend to work better than admonishment to improve performance.
I imagine that two days ago, for some people, those three may have seemed contradictory. Perhaps now, for some people, they may be common sense.
