I work in HE so there's obviously much more turnover in senior management than the rest of the hierarchy but that's individual turnover, there's no need for Jim†, who arrived last week, to task HPC with gathering a quote that six of his subordinates and colleagues already know from last time shows this is a waste of time.
† Name changed to protect individuals but also because frankly I don't care very much who is currently doing these roles, there'll be others.
Higher Education. A University. So, senior management are much the same as anywhere (although maybe with at least enough sense to realise that the mission is now different) but many other people are there because of the mission. Researchers, teachers, even if what you actually do is marketing, there's a very different sense of purpose behind that than if you were selling garden furniture.
