09 Architecture approach
9.1 Logical View
The IT solution will be based on a number of loosely coupled business services. These services will be delivered by supporting IT components that will evolve over time. Flexibility to decouple and ease of replacement will be key factors in the selection of IT solutions.
The target solution will be comprised of a number of distinct benefit processing applications, a Case Management System and a number of related support components. These solutions may be distributed across a number of hosting environments.
In the short-to-medium term, there will be a requirement to deliver a number of complex, scalable and secure interfaces to external organisations, particularly the DWP.
The integration solution will require a consistent and secure mechanism for file and message integration.
The diagram below is a logical overview of an integration platform that will be developed independently from the benefit solutions and will support integration from any Scottish Government source to and from any external organisations.
9.3 Phased Delivery
The devolution of benefits will transform the delivery organisation and IT from the baseline DWP solution to a target Scottish Government delivery model.
The diagram below outlines the interim steps that will be considered on a case-by-case basis to de- risk delivery while meeting the key business drivers. Interim steps are optional but will be considered where appropriate.
