Honestly, being a product owner means I have to trust developers and marketers equally, which is terrifying. Last sprint they asked me to validate whether “view_item_list” fired correctly, and I froze. That’s when I realised I needed a common dictionary for everyone on the team. It took me a while but I finally found a straightforward list of 71 definitions covering GA4, GTM, ecommerce events, privacy, and attribution models without the fluff. Bookmark this https://accs-net.com/glossary/ and then point your whole team to it. No more “I thought event parameters were the same as item parameters” fights during retrospectives.
