The DMS was designed to replace paper-based tracking systems. Data is entered by users or read directly from assay systems, with built-in validation to help reduce the possibility of data entry error. There is a fully integrated approval process including electronic signatures. The scope of this requirement is for the provision of support and maintenance for the NRS Dounreay DMS. This maintenance service must maintain the availability of DMS for the users and ensure that threats and events are proactively managed and mitigated appropriately so there is no detrimental impact to the system and its data. The support service will include: - Availability of a help desk, to log and deal with support calls, with an appropriate Information Technology Service Management (ITSM solution for tracking tickets against agreed Service Level Agreements (SLAs). - Backups of the database. - Repair of defects and issues. - Planned quarterly updates to the servers with the latest stable version of Debian Linux, including security patching. - Un-planned updates as required if critical vulnerabilities have been identified. - Maintenance of all DMS specific related software. - Change management approval and audit trail. - System Upgrades. - Mobilisation and demobilisation for any transition periods required between contracts. Additional to the maintenance of DMS is the requirement for the Consultant to demonstrate the capability to develop and implement new functionality and propose enhanced capabilities to streamline activities which will be scoped and agreed separately under a contract change notice. The DMS is a ‘live’ system and is reactive to changes that will be carried out throughout the decommissioning life cycle of the Dounreay Site. As operational and compliance processes change the DMS will be required to be modified.
