"Complex systems fail where learning is suppressed.
The word suppressed is the hinge. In a reliability improvement that shifts risk elsewhere, it tells you which part of the situation is structural, not personal. That is the part you have to design around.
In a reliability improvement that shifts risk elsewhere, the failure mode is rarely ignorance. It is choosing as if the system were simpler than it is, then being surprised by the interaction effects. You see it in a retry policy change that turns one failure into a storm. If you do not name the cost now, it will return later as rework, pager load, or a standard nobody can enforce.
Chris Argyris is a reminder to keep it concrete. Put the assumption into words, then choose the signal that forces you to revisit it. Make the decision legible to the next person who inherits it.
