Failure modes
Three things stop a plant cold
None of them are a slow laptop. All of them are IT problems that show up as production, customer, or audit problems.
Mode 01 · Production
Ransomware on a flat network
Machine controllers on unsupported Windows sit on the same network as email. One click in the front office and the CNC cells, the ERP, and the shipping labels go down together. Recovery is measured in weeks, not hours, when the backup was never restore-tested.
Mode 02 · Drawings & IP
Drawings where they shouldn't be
Customer drawings, CAM programs, and process specs are often the most valuable thing in the building, and many come with strings attached: NDAs, export controls on defense work, or CMMC requirements in the contract. If they sit on an open share or a personal cloud account, you can't say who has them.
Mode 03 · Quality & contracts
Records you can't produce
Quality records, traceability, certs of conformance, and inspection data all have retention expectations, whether you answer to ISO 9001, AS9100, an FDA auditor, or a customer's supplier quality team. “We think it's on the server” is not an answer during an audit or a bid review.
