I think there is a critical balance between education and experience where a person has both sufficient capability and (critically) interest in using it, that enables this sort of thing.

Of course it also requires the opportunity to improve something, which is not universally present. Often the opportunities to improve stem from a recent change in organizational priorities, or the prior party’s lack of interest (instrinsic motivation) or incentive (extrinsic motivation), not necessarily their specialization or lack of understanding.
