We began with a three week inception phase to understand user personas, turn ideas into lo-fi designs and establish agile delivery ceremonies and ways of working. This was important as the civil service team needed to understand what reporting, governance and compliance processes were needed to run the new service along GDS guidelines.
Data needed to be clearly designed and accessible through APIs. These were built to integrate with six accredited schemes, with all services exposed through a documented REST API. Existing data was migrated slice by slice from the legacy system, so it could be used as required by the new service. This was achieved using AWS Snowball.
