Product quality is a CX failure (not a qa footnote)
The two worst quality killers: not testing with users, and not testing on the devices customers actually use.
Product quality is a CX responsibility, not a QA footnote. The worst quality failures come from not testing with users and not testing on real customer devices and setups. The result: broken search, navigation, checkout, and forms — and revenue loss blamed on the wrong things.
Two things damage product quality more than anything else: not testing with users, and not testing on the devices and setups customers actually use. The failures this produces are not exotic. Broken search. Broken navigation. Broken checkout. Broken contact forms. A product that works in theory but fails in real conditions is broken.
Most companies have no data-informed testing matrix. They test on one browser, one device, one viewport — usually the team's own. Assuming your personal device is a proxy for all users is false equivalence, and it is everywhere.
The cost compounds quietly: lost revenue, lost engagement, silent churn, and marketing failures misattributed to campaigns when the real culprit is a broken experience nobody tested.

Reading about product quality is a cx failure (not a qa footnote) is one thing. Seeing where it applies in your journey is the useful part.
