Great comment. Specialization led to splitting teams in frontend and backend teams, thus these teams started develop different coding culture & solutions, like separate build steps and whatnots. No longer could one team finish a feature instead it had to be a cross team cooperation if they could sync their schedules that is. If one team was failing their part the other team either couldn't or wouldn't fix it and the delays increased even more.
