The whole concept of areas of responsibility has developed into a "this is my job - not yours so lay off the landing light switches they are MY responsibility - not bloody yours". And while you are up to it keep your hands off the APU fire switch I will pull it - not you. We now see the ultimate in pedantic stupidity when operators lay down in an Ops Manual exactly what page each pilot must have in front of him on the CDU on take off and during the climb and approach to landing. - conveniently forgetting that both pilots have the ability to select any page they like in less than five seconds on their CDU.
Yep, maddening, ain't it.
However, in my view this is a direct response to the presence of very junior First Officers new to the aeroplane, and the end result is procedures reduced to the lowest common denominator...IE: 'don't think, just do it, you don't need to understand the reason'.
Understanding and reason...out the window.
