The Dounreay Data Management System (DMS) is an existing bespoke developed integrated data management system which records the consignment, movement, processing and disposal of all solid waste on the Dounreay site ensuring that there is an audit trail of the verification of waste packages from cradle to grave. The Contract is required to ensure the availability of the Data Management System (DMS) for the users and ensure threats and events are managed appropriately so there is no detrimental impact to the system and its data. Additional to the maintenance of DMS is the requirement to develop and implement new functionality and propose enhanced capabilities to streamline activities.
