If you find the temporary fix in our example in place of hard pipe, consider implementing the following:
1. Update documents religiously - Treat your P&IDs as live documents, not archives. If the field doesn't match the drawing, you have an unmanaged change.
2. PSSR Required - Build field verification into MOC closeout even if you aren't regulatory. Don't accept "closed" on paper until someone has physically confirmed the field matches the redline.
3. Walk Down More Frequently - Walk down your high-consequence systems on a schedule, not just after an incident.
