There is no need to run out of moronic ideas, also known as "business strategy." It has been shown statsistically that the half-life of a strategy (or moronic idea, if you prefer) is 1.5 years: 1.5 years to become established, 1.5 years to a mature to a peak, 1.5 years to deteriorate, and 1.5 years to be discarded. Thus, an organization needs a change in strategy every 4.5 to 6 years.
However, the ideas need NOT be new and original. Few employees, managers and officers stay beyond 10 to 15 years, which means there is no corporate memory of the moronic, eehhh.. strategic ideas that were utilized before then. The result is that most large organizations are in a loop consisting of the same three or four ideas, each in fashion for 4.5 to 6 years.
They never run out of moronic ideas. They just hit "replay."
