Hi Praneet,
Maintenance Team need to do the Technical complete (TECO) which is the way saying to operation the work is completed and the system is ready to start.
Also Permit has a option to confirm whether at release or at Technically complete the order. In your case if you set the permit at Technically complete the status, then maintenance team / manager has to approve the permit and Technically complete the work order.
Regards
Terence
