When I worked in AAA development, I created tools specifically for QA to use, because our AI system was new and complicated, and I needed them to find the places where it broke down.

Because of my partnership with QA, my bug list was almost always zero or low single digits. https://twitter.com/MushrooQueendom/status/1381689816107024385">https://twitter.com/MushrooQu...

Being a good QA (someone who will find and help to root cause issues so that other developers can fix them) is a skill that needs to be honed over months and years of experience.

When studios treat QA as fungible, disposable, unskilled workers; when they impose bug quotas decreasing the signal-to-noise ratio to the rest of dev - this only serves to harm the end product.

Treating QA as valued team members lets you do more and better with fewer people.
