OT governance and RACI
OT governance works when each plant knows who approves a change, an exception, or a vendor session, and who answers for it afterward. A RACI earns its place when it names those decision rights for people, so site work does not wait on a committee.
These posts show how security, engineering, operations, and safety share that ownership across a fleet of plants.
