Enterprises are facing rapid and radical changes in a turbulent environment. This turbulence requires companies to be agile, i.e. to keep an overview of their environment and to be ready to react. Alignment Businesses IT is constantly being affected if levels of abstraction are affected by the change. The changes in companies must necessarily be accompanied by a (re)alignment of Business IT. In order to measure the impact of change on Business-IT alignment, this paper reviews the literature on agility metrics in different domains, by filtering them to focus on the context of Business-IT alignment, and then matching the metrics to the model that defines the impact of change on Business-IT alignment.

Strategic alignment must touch the long-term evolution. For this, the agility remains the optimal solution for this alignment to remain scalable and dynamic despite the events not scheduled that triggers over time. Making these two keywords work, associating them, makes them speak, combining progressively and meet regularly allows optimizing the work of each other. It is important to find a fair balance between the agile part, which is necessary to the rapid transformation and adapted of the information system and the strategic alignment part, which ensures the coherence, sustainability and the relevance of an information system of a limited duration. Following an enhanced state of the art, our article proposes an approach that will be a good balance for an aligned system which is sufficiently agile to be able to preserve a strategic alignment in the face of frequent developments.
