A few months ago, one of our teams celebrated a milestone in their quarterly review. AI adoption was up. The productivity dashboard showed that developers were generating, on average, 40% more code per sprint. The tech lead showed this as a major win.Three weeks later, I was on a call for a production issue. The challenge was that errors were coming in three different formats depending on which endpoint you hit. The alerting was blind to a category of failure it had always caught before.
