I don't really agree ... doing thing A well usually means understanding B, C and D which underpin A. It's actually quite useful to ask people about B, C and D because if you only ask them to do A you don't know if they are doing A the right way because they really know what they are talking about or if they are just cargo culting something they pretend to understand but have no deep knowledge of.
