The Enterprise Architecture Planning (EAP™) methodology and model are a seminal part of the common body of EA knowledge that remain relevant in their own right and which have influenced a number of other current frameworks, methodologies, and best practices in the public and private sector. However foundational, the EAP™ approach has become, according to some EA practitioners, somewhat dated in its content, presentation, technological examples utilized, and in its relationship to some aspects of how EA is being practiced today. The intent of this article is to refresh one part of the EAP™ approach, the famous EAP™ model (also known as the wedding cake™) and to provide explanations of each part of the updated model.
