Sometimes you get newer management with NIH syndrome. So existing "legacy" project teams (the ones that are actually in production) can get squeezed on both ends. First they get a lot of BAU pressure to not have outages / ship features faster / etc. Second they also get Change pressure to completely re-architect while doing the BAU and not increasing staffing. For some who play chess in the department head seat, it is win win. If the legacy team has more outages / doesn't speed up on features, he has his remit to build his new pet project replacement and 2-3 years before theres any accountability for the outcome. If the legacy team succeeds in re-architecting then he also gets a win.
