On the subject of checklists,procedures,and taxi clearance....
We are so very procedurally oriented that breaking the chain can often have undesirable results..."Flap 5,taxi clearance "... can go out of the window,if the taxi clearance is given,(and received) during pushback..
This caught me,one night,out of Dubai...made me very grumpy with ATC,until i analysed the real cause of taxi without Flap....Me!...
The correct measure of discipline will help to avoid these issues.
