The Turn You Do Not Make: Why Organizations Stopped Trusting Their Gut

Follow a delivery truck long enough and you will notice it avoids left turns — sometimes going three blocks out of its way to skip one. It looks like a driver who got lost. It is actually the visible surface of a ten-year, quarter-billion-dollar analytics project that saves three to four hundred million dollars a year. Everybody already knew left turns were slow and dangerous. That was never the missing piece. The missing piece was scale: one mile removed from every driver’s day is worth fifty million dollars, and no human standing on a sidewalk can see that. This episode builds the three-rung framework that organizes the entire field — descriptive, predictive, and prescriptive analytics — plus how to tell which decisions are worth analyzing, why "big data" is the wrong thing to be impressed by, and why some drivers still beat the algorithm.
