The execution gap framing is accurate, and I'd argue the 24-hour early-warning duty is the single most diagnostic requirement in NIS 2, because it converts "do you have security?" into "can you see an incident, classify it, and decide who signs the notification within one day?" Paperwork passes that test only if the monitoring behind it actually works. Two practical consequences worth naming: management-body liability means the person signing needs evidence they asked the right questions, so board-level reporting shifts from posture summaries to detection coverage and mean time to triage; and the supply-chain scope quietly pulls in small vendors who never budgeted for any of this, so their first NIS 2 expense is usually not a tool but discovering which of their customers' contracts now make them an essential or important entity by proxy.
