Chesterton's Fence, even if there is actual inefficiency there might be a reason for that. It might not be a good reason mind you, but even a bad reason is still a reason. You cannot cut inefficiency without understanding the reason first. It would take multiple years of research to understand and uncover all the inefficiency that has built up over the years. Otherwise you just end up throwing out the baby with the bathwater.
