"Must match SOPs" and "must match your SOPs" can be quite different. Coming from the BBJ side of the house, I can tell you that Boeing;s checklists tend to be airline driven with a minimalistic approach to how things may be done. Where as a corporate operator might inject any number of unique points into the list. Obviously you will want to cover the basic safety of flight points, but there may be other reasons to modify the Boeing boiler plate, one size fits all approach.
