The IT Service Creation teams needs to able to deliver digital services at pace and using the Command-Query Responsibility Segregation pattern with Event Sourced systems of record. The DVLA has little native experience of this pattern and requires a specialist to provide industry best practice experience and patterns for the implementation of CQRS/ES in concrete applications. The IT Service Creation team needs to be able to deliver digital services at a much greater pace than they currently do. The services they develop must have a much lower cost of operation than they currently do. The basic operating model for IT Service Creation has been asserted and we are now beginning to prove that it will work. This has exposed a substantial gap in experience and knowledge. We intend to have around 3-4 squads of mix-capability engineers working on the Vehicles Transformation programme. Who Speclialist Work With They will work with (by providing expert advice) the IT Service Creation delivery squads in DVLA which includes software engineers, test engineers, business analysts and also the Senior Management Team. What Specialists Work On The DVLA requires a specialist to provide industry best practice experience and patterns for the implementation of CQRS/ES in concrete applications. The patterns the specialist will provide will be used by the DVLA’s implementation teams and so we also require that the specialist will review the actual implementations of these patterns. The specialist will work to a pipeline of work that has been prioritised by the DVLA. We anticipate this may take up to twelve months but acknowledge that this could take longer.
