A team I worked with had a 30% drop in iOS reactions on social posts.
Product blamed iOS. "Must be an iOS bug, the new update probably broke something."
Engineering blamed analytics. "We didn't change the reaction code. Must be how the data is being collected or analyzed."
Two weeks of debate. Three teams pulled in. Real product decisions delayed because nobody could tell whether the data was real or the tracking was broken.
This is what happens when nobody owns analytics tracking end-to-end.
Product builds features. Engineering implements them. Tracking gets added as an afterthought, then drifts as the product evolves.
When something looks weird, no one can confidently say whether it's a real signal or measurement noise.
The cost isn't just debugging time. It's every business decision made in the meantime on data nobody fully trusts.
