Defining an architecture for evolving environments.

The architecture of a system specifies how the system should be designed and built. However, shortcomings are identified in current architecture process frameworks concerning evolving domains like healthcare. We claim that an iterative architecture process is required, where the technical concerns are separated from the non-technical ones. Furthermore, a strong guiding vision is required. Based on our experiences from a biobank IT infrastructure process, we present an architecture process that is modular, interoperable, controlled and abstracted, thus being capable of handling complex systems with large uncertainties.
