The shift was around 2018 or so. It was talked about on qa forums and conferences. It likely was talked about at conferences that management go to, but I can’t confirm that. It seems like you must work in a specialized industry. 1 QA to 4 devs is about the standard. And they keep up by cutting corners. The effort required to creat test automation to test a feature is on par with the effort to create the feature. And then you have to add in old tests that need to be maintained. No way one person can cover 4 and not cut corners.
The company that takes the risks gets the product out before those that don’t. And the ones who get lucky not to have a major thing tank them win in the end. That is just how the system works.
I am starting to doubt your credentials. When a salaried employee works 44 hours, it costs the same as when they work 40. And the tougher the economy, the more work you can squeeze out of each person. And no, even in this economy people will leave, not everyone will hang onto thier jobs. And it will be the ones who refuse free overtime that go. This is even amazons well known work model. Only they enforce required firings to take it a step further.
