Abstract. Enterprise Architecture (EA) becomes a strategy plan for enterprises to align their business and Information Technology (IT). EA is developed, managed, and maintained through EA implementation methodology (EAIM) processes. There are some problems in current EAIMs that lead to ineffectiveness implementation of EA. This paper represents current issues on EAIM. In this regard, we set the framework in order to represent EAIM's issues based on the processes of EAIM including: modeling, developing, and maintaining. The results of this research not only increase the knowledge of EAIM, but also could be useful for both scientific and practitioner in order to realize the current situation of EAIMs.
