Under The Scope: The Difference Between Enterprise Architecture and Solution Architecture
In the last couple of years, there has been a considerable number of debates about Enterprise Architecture. What Enterprise Architects do, why it is necessary and how it is different from Solution Architecture (SA) are only a small portion of the questions EA community has to answer day after day.
