Eengr - as I mentioned in a previous post, some large aerospace companies have replaced expertise with process, so the grey-beard who ran the department, was fanatical about every detail of "his" electrical systems, and had enough clout to insist to Project that they consider the AC aspects is long gone.
And (sadly imo) "his" has become "the team's". Back in the day, we emphasized individual responsibility, tossing "a camel is a horse designed by a committee" at those who needed a poke.
I have no idea if Boeing Commercial is particularly far along that path.
