A customer handover that can be demonstrated
Consider a packaging-machine customer that wants production data in its own MES and has appointed a local maintenance company. The production team needs counts and machine states. The maintenance company needs a diagnostic application. These are separate tasks, so establish separate access decisions and show each team how to complete its work.
During acceptance, load an agreed export into the customer's tool. Check machine identifiers, time and units against a known production period. Then open the diagnostic application as the approved partner, try a resource outside its permission and test a new connection after access is removed. Record the configuration and results with the delivery documents.
