Adam Satariano and Peter Burrows on Apple’s supply chain mastery:

Apple’s retail stores give it a final operational advantage. Once a product goes on sale, the company can track demand by the store and by the hour, and adjust production forecasts daily.

There were a lot of little nuggets in this story that made me stop and chuckle, such as buying all the available air freight prior to the holiday season.
