The Norwegian Defence Estates Agency has established integrations between different internal and external data sources. We see a need for consultancy services for the maintenance of these integrations at the same time as there can be new needs for integration between different data sources in the future. The Norwegian Defence Estates Agency is looking for a service provider who can provide resources that cover the necessary disciplines and work assignments within the development, maintenance and operation of the integration systems, and who at the same time can contribute as a consultant and sparring partner in the selection of integration patterns, technologies and architecture - both for the continuation of the current systems and for the goal picture in the longer term.
