Consensus that these processes are really the best way to do things is relatively recent, and I wouldn’t be surprised if there are a lot of shops that haven’t yet retooled to them. Continuous integration was only proposed as a concept 30 years ago, and was a relatively fringe theory for another decade at least. Automated deployment followed a similar path, but about a decade later. Manual acceptance tests, in particular, remained quite common a decade ago even at the big tech giants.
