The 3 AM Pager That Changed My Prioritization Framework
A critical surveillance model started flagging 400% more alerts at 3 AM — all false positives. Instead of patching the threshold, I led a post-mortem that revealed we had no cost-of-error framework. I introduced a precision-recall cost matrix tied to regulatory penalty data. False positives dropped 60% in two sprints, and the framework became the default for every new model launch.
Lesson
“When the system screams, don't silence it — decode what it's telling you about your process gaps.”
