Checks First
Diagnose, approve, verify
HJ separates diagnosis from the final repair or upgrade so the customer can approve the documented action.
Confirm ownership & boundary
We identify administrator access, warranty, third parties, regulated scope and customer responsibilities.
Inspect & diagnose
A technician checks the agreed system path and records findings before replacement or reconfiguration.
Approve the action
Repair, replacement, configuration, testing or upgrade proceeds only against the confirmed scope and quotation.
Verify & document
HJ tests the agreed outcome, records remaining limitations and recommends the next maintenance action.

System ownership and serviceability boundary
Emergency voice, evacuation and fire interfaces require separate confirmation with responsible consultants and appointed specialists. Component-level repair depends on serviceability and parts.
General boundary: an assessment does not guarantee spare-part availability, data recovery, uninterrupted service or compatibility with unsupported equipment. Work proceeds against the confirmed quotation and customer authorisation.
