CMMS / EAM
Installed base and preventive work imported
Locations, assets and the preventive plan come in from an export of your CMMS or ERP — SAP PM, Maximo, Fiix, Limble, MEX or whatever you run —, keyed by asset code, so a re-import never duplicates. The tree you already have is the tree Norlan uses.
Write-back
An incident closed in Norlan can create or update the work order, and the order's status comes back to the thread. It is the pattern that repeats most in the market — issue, order, status back — and the one that stops a memory from looking like a silo.
