Checklists

Here's something I occasionally wonder about:

How much can automation do for you, if you have to have a person in the loop?

For example:

In one of the Star Trek movies, the automated system reads off items, and the crewman responds - "Main stage flux chiller" "ON" "Auxiliary thrusters" "OFF"...and so on. I'd think that it wouldn't take too much before the crewman learns that when you hear the sounds 'Main stage flux chiller', the response is 'ON' -- to the point where the crewman could do it in his sleep. He's not really checking it any more.

How do you keep that interactive alive, so that the person really is validating the environment?
