Critical Questions in Enterprise Architecture Research

The current enterprise architecture (EA) theory originates from the Business Systems Planning (BSP) methodology initiated by IBM in the 1960s and describes EA as a comprehensive blueprint of an enterprise organized according to a certain framework and describing the current state, the desired future state and the roadmap for transition between them. However, in this paper I demonstrate that the current EA theory poses more questions than answers and is, arguably, in an unsatisfactory state. This paper highlights the critical questions in EA research and is intended to spark further conversation in the EA research community. All the formulated questions address the fundamental aspects of the current EA theory that are critically important for the whole EA discipline. Although this paper does not propose any answers to these questions, it makes a non-theoretical contribution to the EA discipline by critically evaluating the current EA theory, provoking new thoughts and stimulating further research that will substantially alter the EA discipline in the future.
