The first signal may be organisational: a product line is led from another site, chief engineering moves, configuration authority changes location or a bid is coordinated elsewhere. R&D budgets, common software, customer ownership and make-or-buy decisions tend to follow. New work packages then concentrate where technical authority sits.
Legacy backlog can mask the shift for months or years. The plant continues to operate, headcount may look stable and committed investment is completed. But if new bids are no longer led locally, the site enters the next cycle with less margin, less intellectual property and less capacity to generate its own future workload.
Only later do social indicators emerge: hiring freezes, fewer external contractors, unfilled turnover, mobility, lower supplier orders and, if the gap cannot be absorbed, potential involuntary exits. That is why the dossier places industrial authority ahead of redundancy numbers in its early-warning system.
Employment is protected when product authority is allocated, not when redundancies have already been announced.
