What is it?
(OP)
Recently I've been hearing a term very often "Normalization of Deviations". Please shed some light on it.
Thanks

I think your 2nd post hit it. That same term was used in regards to NASA and the loss of the 2nd shuttle. Foam was observed before coming off the tanks, no reason to think it damaged the shuttle...
IMO, it means people get used to deviations (they become 'normal' events) and thus potential safety issues crop up.
For instance, say your car develops a slight shudder one spring day, but it only happens at highway speeds and when you are turning left on curves. No big deal you think, car is driving fine, it becomes just an annoyance. Then the weather warms up, spring turns to the heat of summer. You're driving home, here comes that left turn and the expected 'normal' shudder, but that shudder gets suddenly worse and your tire tread totally delaminates, you lose control, go into oncoming traffic and head on into a semi, and BOOM, your DOA.
Should have looked into that shudder a while ago, eh?

A pattern so grand / And complex
Time after time / We lose sight of the way
Our causes can't see / Their effects.
