Step-by-step explanation:
When change is introduced, there is typically a decrease in productivity followed by a gradual return to or surpassing previous levels. This pattern can be represented by the J curve, Delphi curve, or Change curve. For example, in the late 1990s, there was an unexpected rise in productivity in the mid-1990s, leading to a decrease in unemployment rates. However, productivity growth can vary over time, with some periods showing faster growth and others showing slower growth.
