This is an aspect of Product Management that I don’t see mentioned very often. What negative side-effects of launching this new feature could there be?
… One regular feature request that we discussed was being able to automatically post your trips on Facebook. It sounds like a simple feature – “I’m taking a trip to Paris! Let me share that with my friends!” But as our team discussed it, we realized how easily this could go wrong. We could see a very short leap to a scenario where our app posted that someone was going to be out of town for the next week, and gave potential thieves the exact dates during which their house would be empty. Or a user forgot to turn off this automated feature before flying to another city to interview with their company’s biggest competitor…and their boss was a Facebook friend. We decided the risk wasn’t worth the “fun”.
