Resilience Engineering scope includes a better understanding of the functioning of organizations to improve their ability to anticipate adverse and beneficial conditions and to act effectively. Indicators related to resilience provide important information showing how the ATM system adapts and works to decide where and how act. The SCALES project addresses the research question: What added value can the combination of Enterprise Architecture with Resilience Engineering bring to measure the resilience potential of the ATM system? This paper outlines the SCALES framework, its application to a concrete case and discusses preliminary findings regarding indicators and patterns. The discussion reflects on added value to solve the research question, including theoretical and practical implications. From the current work we can conclude that the complementary strengths of Enterprise Architect and Resilience Engineering enable improved capability to identify resilience indicators and patterns for ATM complex socio-technical system. Further validation in the projects case studies will be performed to further develop the framework and strengthen this conclusion.
