Yes, and issues will always occur. What I was trying to point out that it's never an individual's fault alone. Sure someone might have tripped the final domino but they might not have had anything to do with everything else that happened. That's why blameless postmortems are a thing. Blameless (to me) doesn't mean that you don't name any person but rather that there's no blame assigned to anyone. I want to know what Person A did to cause the incident but there shouldn't be any retribution against Person A.
