Yes, QA is important. My code will always "work" in that everything I tested is bug free. But having someone other test, especially someone who knows the service is gold.

But there is also bad QA: The most worthless QA I was forced to work with, was an external company, where I, as developer, had to write the test sheet and they just tested that. Obviously they could not find bugs as I tested everything on the sheet.

My most impressive QA experience where when I helped out a famous Japanese gaming company. They tested things like press multiple buttons in the same frame and see my code crash.

I do think the type of testing where QA just follows pre-generated script has place. But it is about long term regression. The first round absolutely should not find anything. But with complex system it also should find nothing in a year or three or five years... Offloading this to dedicate resource could be useful in certain industries.

		I did not think of that. Maybe for some industries, it might make sense. But if I want a regression test, I would probably set it up as automated test. In the case I mentioned above it was the only test beside my own for a new service.
