So for me, the QA team is the best source of product information in the entire engineering team. If they also do customer triage, then probably in the entire company. They should know the product inside out, moreover, they know all the annoying bits that are unsexy and not actively developed. yes, they find bugs and junk, but, they know how your product should be used, and the quickest/easiest way to use it. Which are often two different paths. Bring your QA in the product cycle, ask them what the stuff that pisses them off the most. They also should be the masters of writing clear and precise instructions, something devs and product owners could learn from.
