Having worn hats in both PM and QA roles I do agree that a PM should know their product well. However, as a user, I see way too many bugs damage the UX as a result of not having dedicated QA resources. A solid QA team or person can make the difference between a product simply being released on time and saving the life of a product long term by knowing when not to sign off on it due to critical user facing issues. I've seen orgs reduce the QA team first with the idea that it's a bearable cost reduction and have to eat the costs later while the brand's image gets slapped in the process. If an org walks the UX talk, it needs dedicated QA resources - often folks likely to catch issues that others too close to the P&L or design/dev process miss. Been there, done it, don't skip on QA or try to diminish its role. Everyone is responsible for QA just as much as everyone is responsible for UX, but that doesn't mean skipping the QA role. Everyone contributes to the P&L and delivery timetable - should we eliminate the PM role too?
