I really don&#x27;t like the last step of the post-mortem. &quot;Who is to blame?&quot; I much much prefer &quot;how did the system fail?&quot; We want engineers trying crazy things and hit bumpers when they, for example, autoplay sound. The alternative is being hesitant about trying crazy things.<p>I mean, yeah, personal responsibility, but google already has a preflight checklist with code reviews and tests and such. Treating it as a systemic feature protects a lot of stuff you want.
