Having been an engineer in control room environments for both rocket launches and fighter jet flight operations -- it's not really "officialese bullshit". Aerospace has a definite jargon and there are preferred ways of saying things on comms to reduce ambiguities. "Triage the data" is actually a good way of describing what you do in an anomaly investigation. You figure out what the most likely thing that went wrong is, then the next most likely thing, etc. and look at data regarding those things in order.
