Every part of the flight. Here's just one example. When I began to move the aircraft after pushback, my first command was: "Flaps 20", the F/O responded and moved the flap handle. If I taxiied the aircraft more than about 10 feet and I hadn't made the command, my F/O new instantly that I had forgotten. He didn't have to sit over there wondering when/if I would do it. Then after I got corrected, I could think about why I got distracted and say to myself "get back in the game numb nuts."

That was the basic philosophy behind every action being standardized.
