Service Delivery Excellence Model enhances standardized citizen grievance handling and service timelines under Sevottam. Implementation of the Service Delivery Excellence Model establishes an integrated compliance system to operationalize the Citizens Charter and grievance redressal at the Puducherry Commissionerate. The Commissionerate commits to prescribed service timelines for acknowledgements, decisions, release of seized documents, and complaint handling. All HQ written communications must be submitted through a centralized Common Facility Centre or specified web portals, with dated acknowledgements at submission; henceforth the single-window system is the exclusive channel for trade and public communications.
