This Sporting Life
The radical American opera, 1935's Porgy and Bess, by George Gershwin, features an unsavory character, Sportin' Life, who was dealing drugs long before anyone could even spell 'cartel."
Sportin' Life's signature song is it Ain't Necessarily So, addressing such unlikely conditions as the Biblical Methuselah attaining the age of 900.
We face a number of "facts" in supply chain management that ain't necessarily so, either. For example, supply chain is not just another word for logistics. And, what we do in logistics execution is not the same as what common practices were twenty-five years ago. Further, managerial tactics applied to diverse and multi-generational workforces aren't going to work in this century, and employee behavior that doesn't match 1980's expectations is a sign of neither decay or rebellion.
Get over it. What ain't necessarily so is today's reality.
