Yeah product manager says ‘run this on 5% of traffic for 2 weeks and then we’ll see what the next iteration should be’.
In my opinion this all gets back to the way we build product and the expectations we have for our product managers. I have no doubt that their jobs are difficult in many ways, but the lack of actual focus on product specifically as it relates to customer sentiment always strikes me as lazy especially when that data collection is basically passed off to the engineers.
