A rapidly changing business environment, regulatory development, and technological advancements constantly impose changes on the modern enterprise. Thus, the ability to perform EA transformations in a timely manner has attracted growing attention recently within the eld of EA planning. Based on the di erent EA planning perspectives, numerous models and modeling techniques have been developed and examined over the last few years.
