Enterprise architecture management (EAM) is expected to pro-vide business value by guiding the continuous development and transformation of an enterprise. Based on the approach we strive for constructing useful artifacts that guide the successful and situational design of EAM. In order to do so we argue for a tho-rough analysis of the design problem in advance. This is realized by a two-step survey conducted on EAM practices. The empirical analysis reveals eight determining design factors of EAM, a de-lineation of three different types of EAM design in the form of clusters as well as insight about the successfulness of the different types.
