It's easy to say that organizations should do it right the first time, in terms of applying proper engineering practices. But they often didn't have the time, capital, and skillset to do that. Not ideal, but that's often how things work in the real world and it will never change.

Organizations should do it not catastrophically wrongly, especially once a core design / concept is mostly solidified. Putting a little time into reliability and guardrails prevents a huge amount of downside.

I've been at organizations that don't think engineers should write tests because it takes too much time and slows them down...
