Nowadays, companies are immersed in disruptive environments. To thrive in the 'new normal', they drive strategic initiatives resulting in changes with unpredictable frequencies and extents. These changes impact different elements of the company, which makes them a crucial matter for enterprise architecture. However, the traditional management operating models have become overstrained, which leads to existential threats. Therefore, the adaptation of enterprise architecture has emerged. It is an agile approach that continuously senses and responds to change without compromising the alignment in the enterprise. The management of the impact of strategic initiatives is pivotal to the success of companies. Overall, in the context of adaptation, contributions to the proactive assessment and monitoring of the impact of strategic initiatives on enterprise architecture are lacking. Therefore, this study aims to model this impact and evaluate it while focusing on the enterprise architecture structural components and their relationships. It proposes tools to support the analysis. Thereafter, it indicates the applicability of the suggested approach via a case study in a state urban planning agency.
