BRIAN is a business-critical system that will support the end-to-end management of Transport for Wales' in-house Rail Replacement Services (RRS) operation, which is due to commence from 1 November 2026. The system will manage the complete RRS process, including the capture of requirements, planning and allocation of services, operational management activities, and integration with Microsoft Dynamics 365 (D365) via API for supplier payment processing. The system is a key component of the wider RRS mobilisation programme and will support the management of all RRS requirements from initial request through planning, allocation, delivery and payment. As such, it is critical that the solution is fully tested prior to acceptance and deployment into live operation. A comprehensive end-to-end testing programme is required to validate system functionality, integrations, business processes and user workflows. This includes validation of the end-to-end process from creation of an RRS requirement through planning, allocation, operational management and payment processing.
