Law sets a floor
Compliance helps identify necessary responsibilities, documentation and controls. It provides a common language for handling data, informing people and governing certain high-risk systems.
Yet a compliant project can still be poorly fitted to the task, damage work quality or quietly move responsibility onto the user.
Prevention examines the situation
Safety requires testing rules against work as actually performed: room for manoeuvre, exceptions, deadlines, control capacity, skills and effects on collectives.
Law addresses what is permitted and required. Prevention adds another question: under these precise conditions, does this deployment protect people over time?
