After the Thursday night NFL game, I wrote about the poor system design and the need for process improvement with the instant replay system. How could the officials NOT be looking for the replay flag, thrown by the coach?
Well, the NFL has changed their process and has sent training instructions (and a videotape) to all officials and teams. The two Back Judges will now each watch one sideline until the snap of the next play, to make sure they don't miss a coach throwing the red flag, even at the last minute.
It's reactive, but it's process improvement at least.
