That does raise the question of what those tech companies' motivation really are though.

The processes you described would work really well if the goal is to meet a hiring target and ship just enough product that marketing and sales can run with it.

If they don't necessarily care about quality of end product or quality of the engineering that went into, throwing heavy process at the team may get them there just fine. That heavy process may even work better for them if the goal is more managerial control to meet sales and marketing deadlines.

Agile Manifesto was invented by consultants / contractors to make better products for their customers at a good price, not by ivory tower engineers building Platonically ideal software.

Sure, I don't disagree there. In context I was replying to a comment about how big tech companies use agile and similar though.

I do agree though, when used in the specific context of consulting it may be a better fit than in a big tech corporation.
