There are some other takes on the remarks. We don't do it that way may be a way of saying "we can't afford to make any changes because with sequestration we are totally broke". Or, We don't do it that way means our current workforce just couldn't make/handle the change, either because of skill level, or just the climate of the organization. Or, we don't do it that way...that was my pet project in the past and what I designed was good, so don't mess with it. We don't do it that way, because it is the only way I know and if we do it your way, well that would level the playing field and I would lose control of the information hoarding. And, there are rare instances where it could be that they tried it and it bombed out.
