The emergence of the Internet of Things (IoT), coupled with other capabilities such as Cloud Computing and many others, creates opportunities for the development of Cyber-Physical Systems (CPS) at the scale of a digital business ecosystem. It will impact the way engineers work when designing, developing, deploying, operating, or maintaining complex systems-of-systems, with increasing needs concerning security, agility, and interoperability. The Federated Interoperability Framework (FIF) has been developed for Aeronautic Space and Defence over the last years to prepare and build continuous operational Product Lifecycle Management (PLM) interoperability. This paper aims at illustrating, defining, and demonstrating the required evolutionary nature of the FIF from its genesis, by describing past, last, and future evolutions, in particular for the PLM Standards testbed, Virtual manufacturing and CPS. Then Evolvability is defined and discussed, and the provided presentation of the FIF evolutions used to demonstrate its evolutionary nature, making the FIF contributing to the State of the Art and the State of the Practice.
