“…Sloan would later summarize: "We knew nothing about the most recent five or six weeks of our car sales, and this gap therefore was filled with the speculations of the protagonists -the statisticians with their trend lines on the one hand, and the salesmen with their optimistic intuitions on the other" (Sloan, 1964, p. 135). Consequently, in 1924 and 1925 GM implemented a more sophisticated forecasting approach that involved each car division receiving a report from its dealers every ten days summarizing the number of new orders taken, total orders on hand, and the number of new and use cars on hand (Norton, 2004;O'Brien, 1997;Sloan, 1964). "With this information in hand each ten days, the divisions thereafter had an up-to-date, comprehensive picture of the situation in the field," Sloan explained, "The divisions and headquarter staff were then able to take corrective action and make new forecasts with greater accuracy" (Sloan, 1964, p. 136).…”
