Customer Story: How Innovation Norway Modelled its Integrations  

Innovation Norway (IN) is the Norwegian government's principal tool for encouraging innovation and the development of Norwegian enterprises, investing billions of Norwegian Kroner in businesses each year.

The IT team was using non-EA tools and manual processes to model its architecture, resulting in an opacity due to which leadership couldn’t understand the complexity of a project, the impact of change, and what was driving its costs, making it difficult for them to execute data-driven decisions. Additionally, no one in the organization knew what was in the integration layer nor who to ask if something broke down.

Innovation Norway developed a custom application called ‘Doc Master’ to automatically identify all its microservices access control permissions and the relationships between them. It then created a function to import these relationships into Ardoq as references using the Ardoq REST API. Automating the modeling of its integrations allows Innovation Norway to build a rich overview of its architecture quickly. The accessibility of the integration modeling allows the IT team to more effectively communicate with business leaders and guide decision-making.
